Thankful for this! The storage on my ps5, headache

It does great, but two4 TB ones for my pc build they were great even have a game mode

Perfect for ps5 nvme upgrade store all the games I play often on loads super fast

I have looked into compatible m.2 and i looked at this WD as a end all solution. First day in the thing says overheating. I am testing it out with data backup and heavy play. Wish to edit until further notice. Shoudl this be paired with a heat sink?

I bought this in late December 2024 and it died in just 5 months. I've dealt with warranties before with other companies but nothing like this... WD requires warranties to be processed by Sandisk. 1. They require you pay for shipment. 2. Their website gives you a case where you can track the status of your warranty. In 29 days I received 0 updates other than that they received it on 5/9/2025. After asking for the 3rd time.... 30 days later they tell me that the warranty was denied since it's damaged?? okay... in what way damaged? No details just that it's damaged and it wasn't damaged physically at all. It just stopped working.... So they tell me that if I want this back I need to pay the shipping or they will destroy it in 13 days. This is beyond unacceptable... I've deal with Asus, MSI, Gigabyte and even Samsung and NONE come close to how awful this experience was. I feel like I was robbed.... SCAMMED.

Speed & Efficiency: Delivering unparalleled read and write speeds, this SSD significantly reduces load times, making it a boon for gaming enthusiasts and professionals handling large files and applications. Reliability & Durability: WD continues its tradition of reliability with the BLACK SN850X, ensuring stable performance and longevity, giving users peace of mind for their valuable data. Compatibility & Installation: The SSD offers wide-ranging compatibility with most systems supporting PCIe NVMe, and the installation process is straightforward, even for those less tech-savvy. I would also recommend the SK hynix Platinum P41 as a amazing alternative with the speed and reliability to back it up.

Had no problem reserving the item for pickup at in-store location. SSD works great and fit in perfectly with my PC build. Primarily using it for gaming with a ROG Z-890E motherboard. I've had it for about two months and I haven't had any problems with it so far. I recommend this model if you are building a PC that already has a heat sink as part of the motherboard. The model with the attached heat sink will not fit in certain motherboards, so it's less of a hassle to just get one like this with no attached heat sink and use the motherboard's heat sink, especially if it's a higher end motherboard. If you're upgrading a gaming console or you don't have a heat sink built in to your motherboard, you should consider getting one with a heat sink. 4TB drive provides plenty of space for what I need. Seems to work fine in a mid-high tier gaming PC. No complaints!

Fast and sleek 4TB internal SSD! Fairly priced too! Every PS5 owner must own one of these guys! Recommend getting it from Best Buy because of the warranty they offer. It’s a super easy install, keeps the system running smooth and it is great for storing all those DIGITAL GAMES!!! Don’t forget to get the cooling cover, it can also be purchased along with the ssd for a low price through BB! It’s just as described and shown!

so far it has been excellent. REALLY fast, doesn't run hot in my PC, and all the storage I could want. It's has twice the storage capacity and 90% of the advertised speed of the Samsung 990 (actually a bit faster than the 990 on mixed read/ write), and no widespread failure issues.

The speed difference with the WD_BLACK SN850X was noticeable right off the bat! It’s been a night-and-day difference in performance and thermal control. Even while running heavy programs like Revit and Rhino, the temperature stays around 45°C. It’s worth noting that my laptop only supports PCIe Gen 3, so that might be why it stays so cool, but it's still incredibly fast. I also really like the SanDisk Dashboard monitoring software which gives you the temperature of the drive in real time. I definitely recommend the 4TB version for architecture students who need the extra breathing room and reliability.

It’s fast. It’s a lot of storage. What more can I say? Installation is simple (just as all the others). Western Digital has software with firmware updates when needed. Free (defeatured) Acronis software is helpful for moving old data to the new drive if upgrading. It runs kinda toward the hot side, but is stable. Did I mention it’s fast? If you have read this far, just buy it already. You know you want to.

I’ve been using this drive as my main gaming laptop SSD drive for the windows operating system and storage for 9 months now, and it has held up extremely well. It always runs fast and doesn’t overheat. I do recommend using a heat sink when installing in a laptop because this thing does generate some heat under heavy use.

WD SN850X drives are excellent performers. Sure, they won't get you the impressive speeds of NVME 5.0 drives. However, NVME 4.0 is still plenty fast. Based on real-world. Game load speeds are almost entirely unaffected by NVME 5.0 speeds over 4.0. Even file transfer, when the cache runs out, the speed plummets. This is my 5th WD SN drive after switching from Samsung 970 Pro and 970 EVO drives. This is my 2nd 4 TB drive, purchased to upgrade my 2nd PC 1 TB SN7100 drive. 4 TBs for under $270 was the sweet spot. CyberPunk 2077 now loads in 7.6 second oppose to 9 seconds on my old drive. So yeah, slightly noticeable speed improvement. With that said, this drive is worth the money. When installed, you will get about 3.64 GBs instead of 4 TBs of usable space.

Man 4tb in the ps5 was a life saver as the games got more sophisticated the space to install got higher and lets not forget the mandatory online update with this drive its reads and writes fast enough for zero slow down on the ps5 i tried external drives just never worked that great best bang for your buck

This is a fast drive with plenty of storage and built by a company you can trust. Great for gaming systems.

Used it to expand my storage even further. Price was great. It performs as expected. It is best to purchase a heatsink for it. Highly recommend it.

This is an absolute beast! Its PCIe Gen 4 x4 interface delivers blistering speeds, making load times practically nonexistent. The 4TB capacity provides ample storage for games, media, and work files, eliminating the need for constant data management. Installation was a breeze, and the drive's sleek design adds a touch of style to my build. With top-notch reliability and performance, it's a must-have for anyone seeking the ultimate storage solution for their high-demand applications.

Yo, this WD Black SN850X 4TB is a straight-up beast! Installed it, and man, this thing flies. If you’re still running Gen 3 NVMe drives, you’re playing yourself—this Gen 4 monster is stupid fast. Load times? What load times?! Everything’s instant. I use this for audio and video production/editing, and it handles huge files like a champ. No lag, no stutters—just smooth playback and lightning-fast exports. 4TB of space means I’m not constantly shuffling files around, which is a lifesaver when working on big projects. Temps stay cool even under heavy loads, and I’m not seeing any throttling. Read/write speeds are exactly what they promise—blazing fast. If you need a high-performance SSD with massive storage, this is it. Just make sure you got a Gen 4-compatible motherboard to unleash the beast. Final verdict? No-brainer upgrade.
