The box is small and clean. It's matte black with red circuit graphics running across the box. It has a diagram showing the lineup and it sits right below the top tier Optimus GX Pro. Inside you get a clear plastic clamshell tray and nothing else. It doesn't come with a screw but every laptop I've had has a screw in the additional SSD slot. The drive comes out easily, there's no frustrating blister pack to tear apart. - Design & Build - The Optimus GX7100 is a single-sided M.2 2280 board which means it houses all the chips, controller, and NAND on one side. The back is basically blank. This is a big deal in a laptop because we usually have a thermal pad on one side and a hard floor of the motherboard on the other side. This ensures everything sits flush. The drive looks minimal which I prefer, no heat spreader, and no RGB. - Performance - Installing it in my gaming laptop was about as easy as it gets. Open the back panel, unscrew the additional drive bay screw, snap in the Optimus GX, screw it down, close it up. Because it's single-sided the laptop's thermal pad pressed against the drive exactly the way it's supposed to. I set it as my D Drive with a GPT simple volume which gave me 931 GB of usable space to work with. I ran CrystalDiskMark like I usually do with new drives to see its performance. The numbers represent how it actually feels when I'm gaming. Sequential reads were 6,876 MB/s and writes at 6,617 MB/s on the big 1MB test, with the 128 K sequential run sitting right there at 6,820 read and 6,428 write. Those reads are a touch under the rated figure on the box, but that's what I expect from a real run inside a laptop rather than a lab benchmark. Any way you look at it, it performs very close to the theoretical max, impressive! Random performance gets more interesting. At high queue depth the drive scored 989MB/s random read, which is genuinely quick and explains why games load so fast and launching apps feels so responsive. For gaming and everyday laptop use this SSD gets it done. In actual daily use, this drive does what a good Gen 4 NVME should do, it's so smooth you don't notice it, and that's a good thing. Boot times are quick, Windows is responsive and gaming storage feels fast. After a long gaming session when the laptop starts heating up and the fans are ramping up, this drive holds steady. There's no stutter, or spike in load times. Power wise, it's not pulling power like the higher watt SSDs either. - Pros / Cons - * Pros * Single-Sided board does well with thermal pads and tight spaces * Strong Real-World Gen 4 speeds (nearly 6,900 MB/s sequential read in my testing) * Quick high-queue random read for fast games/apps * Runs cool * Power efficient * Suggestions/Needs Improvement * A mounting screw would be nice in case it's needed For a gaming laptop upgrade or additional storage the SanDisk Optimus GX 7100 1TB is a great choice. It's single-sided design and easy install gets you up and running quickly. Most importantly, it performs well on a high-performance gaming laptop, running cool even in those longer gaming sessions. I highly recommend it.

Who doesn’t always need more, faster storage? I have large HHD storage capacities for archive and file storage, but I was seriously lacking in fast, SSD storage space in my editing PC. Plus there’s been this m.2 space just sitting there empty (next to the vacant RAM slot too) that I really wanted to fill. Now, this has NOTHING to do with the quality of this drive, but I swear, I’m never buying a prefab PC again. Times were tough, there was only one way to get a decent graphics card; buy it with the whole PC wrapped around it. But I won’t do it again! Every time I have to open this case up, nothing is as easy to get to as it should be. In this case, removing the aforementioned graphics card that I love was not as easy as most. Sure, just two screws and a PCI slot release…and 5 other tiny screws I definitely dropped into the abyss too many times, the front cover, 3 cable connectors and plastic tabs that are definitely broken now. The point is, if I’m diving into this case to add parts, I hope they’re worth it. And this drive was worth it. Thankfully M.2 installs are crazy easy but it was at that point that I put together that there is no heatsync or anything on this drive. I guess it’s not needed? My case, for all it’s annoyances, does have decent air flow though and I’m not that concerned with temps. Formatting was as easy and straightforward as any new drive install and I was up and running right away. I did a benchmark test for fun to see how much better this is than my smaller, older 500GB SSD to see just how much I may notice in speed differences. Apparently a lot. Faster read speeds and write speeds almost doubled. It’s just a better drive on all accounts. Now, that said, my older SSD is just that, older. I attached the screenshots of both drives, the more full/smaller capacity drive is obviously my older drive and the sandisk is the “S” drive that is empty. So far I haven’t had too much time to get a lot of real world use on the drive, but after I ran the tests, I started moving files from my old to my new and it seems to be working just fine and writing along. Having more space and faster speeds means my editing software can work faster, my gaming should run better, there’s no downside here. I think for the average, to slightly above average user who is doing a lot of gaming or creative work that requires above average drives, they won’t be disappointed with this drive. I just wish I went for 2TB or more. There’s never enough storage.

I have a Gigabyte Aorus Master x570 motherboard paired with AMD Ryzen 5900X. I already have two NVME drives installed in slot A and B. Checking online, slot C would only be PCIE 4.0 x2 at up to 3500 MB/s. Which is half of what this drive can do. So I had to decide on which slot to install it on. If I chose slot A, I would have to reinstall Windows 11 and all the apps and games. Or move my current data drive from slot B to slot C and install the Sandisk to slot B. I chose to do the latter. Windows picked up the drive no problem. It won’t show up in “This PC” or “My Computer” until you initialize it. You can do so in System > Storage > Disk & volumes, or search for “Initialize disk”. Make sure you select the correct one and format it. 1GB sequential making sure no cache I get 3769 MB/s write and 4023 MB/s. I used Powershell command with System.IO.FileStream class to run this test. I ran it a few more times. 3966/3667 MB/s and 4163/4055 MB/s. I Googled to see if copy files from one drive to this drive would be a good test. It says that Windows will heavily cache the file and will inflate results. The numbers are a bit on the lower side then I remembered that slot B is on the chipset and not directly connected to the CPU PCIE lanes. The bandwidth maybe sharing with other peripherals such as network connectivity, other SATA devices such as hard drives (which I have a SATA HDD), the other NVMe on slot C and USB devices. Although, I’ve unplugged all USB devices. But at 4000 MB/s read and write are great speeds in my opinion. Doing some research, application launches you won’t see a difference. Game assets load in small random reads around 4K-128K blocks and not sequential. I’ve reinstalled Officew 365 off my C: drive and installed it F: drive. I could not tell the difference. Most of the apps I use now are cloud apps also which definitely will not be impacted. However, transferring large files like 4K video if you’re editing can be a difference. But are you transferring over network? To another internal drive that’s on the chipset? USB or thunderbolt device? The speeds I’m getting are more than enough. This is a really fast drive. The numbers I shared are for comparison. For me, I cannot tell you any difference with opening apps on my C: drive (PCIE on CPU) vs F: drive (PCIE on chipset). I like this NVME drive.

The Sandisk Optimus GX is the fastest rated PCIe 4.0x4 SSD that I’ve owned to date, and it meets that expectation with super fast transfer speeds, consistency, and reliability. I’m using it as secondary storage for games and backup purposes in a PCIe 4.0 slot, and the fact that it’s single-sided makes it slim enough to fit in my gaming laptop and still have enough room to add a passive heat sink sticker. Setup was quick and straightforward with a quick format and partitioning after installation. The drive advertises max read/write speeds of up to 7250/6900 MB/s and during testing, the benchmarking software results came pretty close to those figures. This drive does not have a DRAM chip and uses HMB to cache the mapping in your system’s RAM, however, the added latency is generally imperceptible during real-word use unless the drive is nearly filled to max capacity. The drive also employs SanDisk’s nCache which uses some of the NAND flash as an SLC cache for fast initial transfer speeds, however, write performance will slow to a crawl off once the cache is exhausted, for example, if I try to move hundreds of GBs of 4K video files to it, and the cache size dynamically scales with the drive’s free capacity, so it shrinks as the drive fills up. To avoid these slowdowns I generally try to limit the size of data transfers to the drive by performing more frequent file backups, rather than copying over huge blocks of data all at once. For gaming use, it has more than enough storage space for numerous installs and load times on the games I played loaded from the drive were quick and seamless. It also has excellent power efficiency and runs cooler than my older gen SSDs, with idle temps measured around 30-40°C and 50-65°C during sustained peak writing and gaming, so I get more game time on battery power and less heat output. With a 5-year warranty and 600TB write endurance, I expect this drive to last a long while.

So hard to believe how tiny these drives are now, let alone how fast they can be too. This one is pretty much on par with another one of my “Pro” drives with my only limiting factor being my motherboard. For my system, it is a pretty easy snap in place and then snapping of the heatsink over it. It is highly suggested to have some sort of heatsink system for these types of drives as they get hot quick. Most modern motherboards have snap in systems, laptops even have smaller thermal pad type systems. But, if yours does not, look into getting something to help distribute the heat better as that can ruin your performance and lifespan of the drive. Once installed and powered back on I just needed to do a quick format through Disk Management on Windows and everything just works as expected. Having the extra space is pretty essential these days, but still surprising how quick you can fill up 1TB. There is a SANDISK Dashboard you can install from their site to provide more information about the drive, check firmware and enable game mode. Although, I personally did not see any real difference with that mode enabled as it was all just fast. A Crystal Disk Benchmark did give slightly higher random 4KiB Q1T1 read/write speeds than before enabling it, but slower Q32T1. But, only by about 10-25MB/s. Overall, this drive is everything it claims to be with speeds and performance with a 5 year warranty.

I have been using a 2TB Samsung Pro 980 for a few years now. It has been a reliable workhorse, but when it comes to flash storage, really anything flash, memory etc... it is always evolving into something better than the previous iteration. So I was excited to see if the new SANDISK Optimus GX 71000 was going to outshine ole reliable. TLDR, it did. One thing off the bat that I find interesting about the marketing for this SSD is that it seems to be targeted for mobile/laptop devices. However, I am running this in my custom PC build, and I could not tell a difference in performance. In fact, speaking of performance, that is where I was quite surprised with the benchmarking results compared to my Samsung. Here are the results using crystaldiskmark Sequential read: +15.2% faster 5,304 MB/s vs 6,099 MB/s Sequential write: +50.0% faster 4,325 MB/s vs 6,443 MB/s Random 4K read: +24.2% faster 372 MB/s vs 489 MB/s Random 4K write: +33.6% faster 404 MB/s vs 557 MB/s The sequential write was where I was quite impressed. I am going to chalk it up to their advanced NAND architecture and cache technology they have on this drive. Loading up games that are over 50GB takes seconds such as Fallout 4, Warzone, Oblivion etc... Overall this is a great drive with excellent performance in gaming. Boot times, loading screens, write performance, all excellent.

One of the easiest ways to upgrade the storage on your gaming computer is to install a new NVMe SSD. Whether you are replacing the OEM drive or adding a new drive to an open M2 slot in your gaming system the Sandisk Optimus GX is one to consider. The Optimus GX is designed for gaming and it balances high speed performance with reliability. Note that this drive is thin and does not have external heat sinks which makes it more compatible with various thin laptops and gaming systems but it also could be an issue if its located near a high heat source. In my testing this Sandisk Optimus GX did outperform my OEM WD Gen 4x4 drive by as much as 25% on the CrystalDiskMark benchmarking app. However due to the high cost of storage these days it’s tough to decide if the improvement was cost justifiable over a slightly slower NVMe SSD. My gaming computer’s OEM drive was nearly full and it had a second M2 slot so I added the Sandisk drive to give me more storage. Installation: Installing an NVMe drive is simple if you have an open slot. You physically mount the drive and then use Windows Disk Management to get it recognized and formatted. Once it was formatted I used Steam’s settings to move my games onto the new Sandisk drive. Sandisk has a Sandisk Dashboard software app that monitors the health of the SSD. There is also the Acronis image software app that allows you to copy over an entire drive. This is useful if you are replacing an existing drive.

The SANDISK Optimus GX 7100 NVMe SSDs with PCle Gen 4.0 is the SSD that you need when upgrading or expanding your storage. Not only are you expanding your storage but you are also getting increased read and write speeds. SANDISK claims the Optimus GX 7100 NVMe SSDs can get up speeds of 7,250/6,900MB/s (1 TB and 2TB models) and they are pretty accurate with that claim. I installed the Optimus GX 7100 into my free M.2 slot, which was easy to do as these types of SSDs are plug and play. The only thing you will actually need (in my case) was a screw for the SSD. After installing the Optimus GX 71001 updated and formatted it using SANDISK's included software SANDISK Dashboard which also allows you to enable Game Mode. Game Mode enhances drive performance for gaming workloads. After installing the Optimus G 7100 I transferred my entire gaming library to the SSD and I was off and gaming in no time. My games boot up fast and l am happy with my choice of SSD. I would recommend this product for anyone looking to upgrade their storage.

I’ve had an empty NVMe slot in my gaming desktop staring at me for months, and eventually I caved. More room for Steam games isn’t a bad thing, right? So I picked up the Sandisk 1TB Optimus GX 7100 NVMe, hoping it would give me some additional, fast storage for my games. Installation couldn’t be easier if you already have a free NVMe slot. It’s plug‑and‑play. The only hiccup, and honestly a bit surprising, is that it doesn’t come with a heatsink. For a drive that’s clearly meant to handle fast transfers and gaming loads, that feels like a big miss. If your motherboard doesn’t have built‑in NVMe cooling, you might want to pick up a heatsink separately to avoid any possible thermal throttling. That said, once it’s in, the drive performs really well. It’s not Sandisk’s flagship gaming model, but it’s still pretty fast, and in my basic Windows 11 tests it hit the advertised speeds without much trouble. For gaming, storage and video editing, this drive is more than adequate. Pros: -Easy installation -Fast drive that reaches advertised speeds in real world use -5 year limited warranty Cons: -No heatsink on a gaming focused NVMe is a shame Overall Thoughts: If you’re looking for a NVMe from a reliable company that stands behind their product with a 5 year warranty and that keeps up with all but the fastest NVMe drives on the market, then this Sandisk Optimus GX 7100 might be a good fit, just bring your own heatsink.

I grabbed the SANDISK Optimus GX 7100 1TB to replace an older, aging drive, and the performance jump has been immediately noticeable. If you are looking to eliminate loading screens and make your system feel incredibly responsive, this Gen 4 drive absolutely delivers. The Good: Incredible Speeds: The advertised read speeds of up to 7,250 MB/s are no joke. Booting into Windows takes mere seconds, and large file transfers happen almost instantly. If you work with large creative files or heavy applications, the responsiveness is night and day. Flawless Loading Times: Loading into heavy, modern asset-heavy programs or games is practically instantaneous. It supports Microsoft DirectStorage, which makes a massive difference if you're running software optimized for it. Great Efficiency: The architecture is surprisingly power-efficient. I threw this into a laptop setup, and it doesn't drain the battery or turn the machine into a space heater under a heavy workflow, which is a massive plus for an M.2 2280 drive. Solid Peace of Mind: It comes with a 5-year limited warranty and uses SanDisk's nCache technology. Knowing it’s built on reliable TLC 3D NAND means I don’t have to worry about drive degradation from heavy daily use. The Bad: Premium Price: At $299.99, it is definitely a premium investment compared to budget Gen 4 drives on the market. You're paying for top-tier read/write limits and a highly efficient architecture, but it might be overkill if you just need basic extra storage. No Included Heatsink: It doesn't come with a built-in heatsink. If you are installing this into a tight desktop layout or pushing it hard with sustained write cycles, you’ll want to make sure your motherboard has a good integrated heat shield to keep it running cool. The Verdict If you want to maximize the potential of your PCIe 4.0 setup, the Optimus GX 7100 is an absolute powerhouse. It's fast, power-efficient, and rock-solid. It’s a bit of an investment, but for a primary drive where speed actually matters, it’s worth every penny.

I was looking to upgrade one of my laptops from the 512 GB that it came with to at least 1 TB. Of course, it is a bad time to be buying storage with AI sucking up storage and driving up prices for everyone. For a good amount of time, I could buy 2 TB NVMe for about $100, these days the prices are floating in the $400-$1000 range. Over many years, I've owned several Sandisk storage devices. Several SSDs (internal and external), a handful of SD Cards, a cup full of USB Flash drives and memory card adapters. I may have had one SSD fail out of all these products. In other words, I have found Sandisk products to be very reliable and consistent in performance. When I'm looking for NVMe drives, I'm drawn towards PCIe Gen 4 or higher. In the case of the laptop I was targeting, it's an older laptop, but it supports PCIe Gen 4, so I expected at least 6,000 MB/s speeds. Which is much better than the original 2000 MB/s I was getting with the original. The Sandisk Optimus brand is the new identity of the WD_BLACK series of storage. I've been running Western Digital Blacks as early as the 1 TB mechanical hard drive models. The Optimus GX 7100 is aimed at gaming and delivers up to 7,250 MB/s read and 6,900 MB/s write speeds. To facilitate my storage transfer, I have an inexpensive NVMe to USB adapter and ran the transfer operation via Clonezilla. Clonezilla is a live Linux image. It ran for a few hours and then I was able to swap the drives. While still on the first boot of this Sandisk Optimus drive, I ran a speed test and was very pleased to find that the Optimus was about 3x the read and write speed of the original NVMe drive. I'm feeling a lot more comfortable with the 1 TB of storage space. The original 512 GB felt a little claustrophobic these days. Overall system performance seemed to improve slightly. I then started to play some of my usual games and felt a noticeable improvement to my game loading experience. I'm very glad that I could swap into this 1 TB Optimus GX drive.

After whipping this drive as well as I know how, I have nothing but good news to report! One very interesting little thing I noticed on here is there is 1 storage chip, just 1. All of my other drives have always had 4 or 8, but there is just 1 here. It looks like those of us with “just” PCIe 4.0 will get a taste of what it’s like using the new standard, as it is able to stay completely out of the way of everything else the machine is doing. My gaming machine currently is sporting an X570 chipset. I have been using what I thought were fast drives. This one promised to saturate the PCIe 4.0 bus on my machine, which is such a satisfying and rare treat. I did not wipe my machined set this one up as a boot drive. Instead, to make sure my games were going to get to use as much as possible, I set this one up for just running games. I put Forza and Battlefield 6 on here to get a feeling of if the upgrade is worth it. The good news is under normal operation, there is no difference at all. No slowdown or mysterious behavior. BF 6 loads incredibly fast, but it did before. When I first ran it, it had to do it’s shader business, I didn’t notice a difference there. I did notice a very important difference while playing, though. I have always experienced hiccups while in-game where I will get graphical or audio stuttering, I figured this was just my computer. All of that behavior is gone now. It’s so buttery smooth. I still get the same framerate, but the experience is waaaay better. The new Forza is AMAZING, I absolutely adore the ability to be able to not every give my storage a second thought. It’s quite satisfying to experience the true performance capability of my computer after all these years as the “future proof” tech is now mature. Recommended!

If you are looking to upgrade your gaming and productivity experience, I would highly recommend getting this SSD from Sandisk. I decided on 1TB Optimus GX 7100 PCIe 4.0 x4 M.2 module and updated my current gaming PC with it. As you probably know the upgrade and installation is pretty straightforward and easy. There are a number of great benefits and improvements with this drive. I think compared to cheaper QLC‑based SSDs, this Optimus GX 7100 uses TLC NAND, which means: 1. You get better sustained write speeds 2. This drive has definitely better endurance 3. I find it also has more consistent performance under load compared to my older SSD from another brand. This is why it’s marketed as a gaming and enthusiast SSD and you will find it costs a lot more. In my gaming experience (mostly AAA titles and open‑world games), the advertised up to 7250 MB/s read and 6900 MB/s write speeds support fast game loading (you will definitely see the difference in load times); smooth texture streaming and quick level transitions. This drive is also excellent for content creation and productivity, so if you deal with anything related to 4K/6K video editing or large RAW photo libraries go for this drive (2TB would be the ideal size of course). I did a few heavy file transfers and it was significantly faster. The TLC NAND and high endurance (up to 600 TBW) make it reliable for sustained workloads so if you are looking for this type of upgrade, I would not hesitate and get Sandisk. As I mentioned this SSD is not the cheapest option out there, however weighing all the positives and benefits, it is definitely worth your money.

SSDs are becoming rarer and rarer. Yet, for the Gaming Enthusiast or Content Creator. Having a fast, reliable one matters. Not that I'm making professional content. The SSD came in a box with no heatsink or pads. I'm fine with this because I can add my own. Being a Gen 4 SSD it will fit in most recent PCIe 4.0 slots. Having the extra storage goes a long way even if it's only 1TB. Having that extra space helps with Gaming. Having that SSD strictly dedicated to gaming and nothing else. For my Content Creation route. I like to keep a separate SSD for Davinci Resolve Cache. This is just Cached files and Images that make the Rendering much easier. These files can get massive for a 4K project. So having a separate fast SSD like this helps when deleting all of that cache. Also, for projects having this as a non-boot drive and just as a "Project" Drive. These are some of the usages I found for the Sandisk 1TB Optimus GX 7100. The main downside is the price. That's the downside of buying anything with RAM or any chip-related technology in this climate. Ideal for a gaming laptop that needs spare space. Slap on a thermal pad and you're all set.

The SanDisk Optimus is the new branding for the popular and highly regarded WD Black Western Digital drives. It has a PCIe 4.0 interface, so it is not as fast as the latest PCIe 5.0 generation, however, it is a very worthy performer at its price point. The max read rate of 7,250 MB/s and write of 6,900 MB/s put it near the top end of comparable 4.0 drives. I replaced a stock M.2 data drive with this one by putting the drive in a USB enclosure and cloning the drive on my Windows PC. I then swapped them out with no issues. I have several games installed on this drive and noticed faster startup time by several seconds when loading from the Optimus drive. I also downloaded the SanDisk Dashboard tool, with it you can check for firmware updates and report on operational information such as drive health, temperature along with other performance metrics. The firmware on my drive was current and did not require an update. With a 5 Year warranty and the reputation and reliability of WD drives you absolutely can’t go wrong with this drive.

I installed this to my Xbox Ally X and tried a few of my games and it loaded up all of my games super fast. The only negative thing I will say though is I wish it came with the heatsink. I could always by a 3rd party one but I like having the one that actually comes from the manufacturer. It does get quite hot but not to the point where it would damage anything but it’s always good to have a ssd with a heatsink. I installed a couple of new games and it installed them very quickly with the read/write speeds. I usually wind up buying Samsung or Western Digital ssd’s but this one is right up there with those 2 brands. I only heard that SanDisk makes great products but never actually tried them until now. I would definitely recommend this to any consumer if you’re looking to upgrade your storage. It’s even better if you’re a gamer. The price is on point for how durable and fast it is. It’s not super expensive. You definitely won’t be disappointed if you’re looking to purchase this ssd. Totally worth it!
