Love this SanDisk - Extreme Portable 1TB External USB-C NVMe SSD - Black! It is small and lightweight. Easy to fit in a backpack or hand bag. I appreciate the cut out to clip the SSD in my back clip. Performance has been excellent. Using bitlocker on it to protect my information.

I bought this when I started a business in Oklahoma last year after retiring my trusty external Western Digital SATA hard drive. I needed something that was reliable, could take a beating, and was fast. After doing research and asking some of my friends in the digital design industry I went with this SanDisk. Although it's more expensive than the Crucial equivalent and the price hasn't dropped much at all, I'm glad I made this purchase. It's a perfect size, has a good feel to it, and I still use it regularly.

Small, fast, ample storage. What more could you want from a portable SSD? This SanDisk Extreme ticked all the boxes for what I was looking for. It has a read/write speed that covers almost any task you'd throw at it and it's nearly microscopic size means you can truly take it anywhere. My only gripe, while very small, is that SanDisk did not include a longer cable. The cable is 6 inches at best and makes using it on certain computers more difficult. Luckily, it's USB-C and cables are cheap and readily available. It would only affect those who don't have extra cables on hand.

⭐️⭐️⭐️⭐️⭐️ I don’t usually write reviews, but the SanDisk Portable SSD truly deserves recognition. From the moment I unboxed it, I could tell this wasn’t just another storage device—it’s a game changer. The design is sleek, compact, and built to withstand real-world use. I can slip it into my pocket without even noticing it’s there, yet it feels durable enough to handle everyday travel and work demands. What impressed me most is the speed. Transferring large files feels almost instant—whether I’m moving high-resolution videos, massive project files, or backups, it handles everything effortlessly. It has completely changed the way I work on the go. Reliability is another highlight. Unlike bulky hard drives I’ve owned before, this SSD is whisper-quiet, shock-resistant, and gives me confidence that my data is safe wherever I take it. In short, the SanDisk Portable SSD is more than just storage—it’s peace of mind, speed, and style combined. If there were awards for portable drives, this one would take the crown. Highly recommended for professionals, creatives, and anyone who values their time and data. F H Foyez New York

Nice reliable SSD that'll fit in your pocket, great for laptops or tablets without much space, especially if you're a creative type who wants to work with a set of files across multiple systems. This is actually my second one! One for steam games, one for storing my music and production samples. Only issues I've had so far is that if you have a drive password enabled, it may re-lock seemingly at random and need to be unlocked again, which can cause issues with large downloads. As such, I tend to keep it unlocked at home. Another small issue is the included cable is quite short, so it's not great for desktop towers unless you make some sort of caddy for it. Overall, I'm very pleased with it, and will probably end up buying again.

Excellent product, super fast, easy to use. Very good price.

I am very impressed with this external SSD. When I read that it was NVMe (Non-Volatile Memory Express), I knew transfer speeds would be very good, but how? NVMe drives are usually reserved for PCs with an M.2 slot on a motherboard, and that translates to extreme speeds. Turns out that when you pair an NMVe with the latest USB3.2 gen 2 standard, it's not a bad combination! Just to get the nerdy stuff out of the way, USB3.2 gen 2 is rated for 10Gbps, which translates to around 1000MB/s. That has got to be the fastest thing I’ve ever had the pleasure of using out of an external drive. To give you context, you can move a 20 gigabyte file to and fro in 20 seconds!! There are some caveats… The host that you’re connecting to must support USB3.2 gen 2 as well. Typically USB Type-C is associated with these speeds, but some hosts will only support USB3.1, which will not get you those top speeds. Perfect examples of this are my test cases: a Samsung Galaxy Chromebook, a Samsung Galaxy Note 20 Ultra, and a custom PC. Each device was able to easily detect and use the Sandisk Extreme. The Chromebook supports USB3.2 with a USB-C port, and I was able to see file transfers go balls to the walls. The Samsung Galaxy Note 20 Ultra, although a USB-C port, only supported USB3.1 and I was getting half the speeds. Finally, my custom PC did not have a USB-C port, so I had to use the included adapter to USB-A in order to connect. Moving to USB-A obviously brought the speeds down to USB3.1 specs. I know SanDisk makes a non-NVMe variant of the Extreme and pricing could possibly be lower, so it’s really up to you to either figure out what devices you currently have and if they support the latest USB3.2 gen 2 standard and go from there. You can also approach this from a future-proofing standpoint in the event that you end up buying new hardware that can achieve those transfer speeds. The drive itself is on the compact side with a rubbery back and a textured front, and the unit feels very solid to me. It has a loop to allow you to hook to carabiner or a safety tether, but you can get creative with it. SanDisk claims some level of water and dust resistance, and that’s actually a very great feature to have if you’re out and about. I think SanDisk hit it out of the park with this all-in-wonder of an external drive for the speeds and the tech that we can attain today.

It holds my high end games that require an SSD. The only problem is the USB cable happens to be too short for my desktop and the converter to 3.0 is proprietary so I had to order a full USB 3.0 cable.

Excellent little SSD. Compact, light, durable and premium feeling! ⚡️fast, highly recommended!

Small with great capacity. All computers recognize this external hard drive. I received many compliments from my friends. No many people knows that this technology is ease available. Great speed of transfer. No moving parts. Very nice price at BestBuy. I bought it as gift for my friend and girlfriend as at gift. They love it. I have 2TB at home for my use. Unbelievable product to use and even to touch the very smooth surface.

I don't know why I didn't look into these before. It's pocket size and carries a lot of data. I've been able to move all my videos from my phone to save storage.

Fast and lightweight. Very small. Little bit hot while writing on it. Works great

I utikize this drive for everything its a quick transfer for my Mac and widnows machines alike. Would highly recommend this product as its dirable (dropped multiple times and still runs) light weight and does the job it was made to do.

Works as expected- very fast, small, light weight, easy to use. My only concern is it gets very warm. Apparently this is a common issue with portable ssd’s. Overall, im very happy and impressed with how fast it moves files. Wish I would’ve bought this years ago.

I already love the SanDisk Extreme's small form factor and water resistant shell. I've had the smaller 500 GB version for a while now. The 1 TB is barely any bigger than the 500 GB with twice as much storage. It has a ring in the corner where you can connect keys or a backpack clip if you wish, and because it's SSD, it's very fast and has no moving parts. It really is perfect for traveling. Stuck at the airport?- Hundreds of songs on my SanDisk Extreme. Long flight? - Movies on my SanDisk Extreme. TV at the hotel is in a language you don't speak? - TV Show seasons on my SanDisk Extreme. Going overboard taking photos on your trip? - Push all the photos over to your SanDisk Extreme and free up room on your camera cards or phone. Waiting forever for the next, bus, tram, train or taxi when you travel? Waiting to check-in, check-out, board, disembark, pass through customs? - Audiobooks on the SanDisk Extreme I can do all of this, PLUS download the contact directory for a 1500-person agency and keep copies of important memos and documents from work, and be able to handle an emergency from the other side of the world. With 1 TB of storage you can do all of that with room to spare. At home, I use 14 TB and 10 TB external drives for storing a complete library of music, movies and audiobooks. When I want to move content from one drive to the other, I use the SanDisk Extreme to move the content. The SSD makes the transfer MUCH faster than transferring directly between two platter drives. I really can't recommend this drive enough. The only way to improve it is to keep going bigger (on storage-not size).

Fast, reliable, and compact! Ideal for on-the-go data storage and transfers. All my photos go there. Keeps my phone and laptop light

Good fast and reliable external ssd harddrive, plenty of space for what i needed and runs very smooth

Slim and compact. A whole lot of storage! This is an excellent little external hard drive. And the best part it is a solid state hard drive so no jarring will mess it up. It is even fall resistant. Nice!

compact but still has plenty of space, fast uploading and downloading

I'm happy with the SanDisk - Extreme Portable 1TB External USB-C NVMe SSD - Black. I needed to transfer many videos from my laptop to this because I only had 3 gigs left in my laptop's memory because I saved too many videos. I didn't know they were such memory hogs! This SSD's transfer is faster than an external hard drive, will last longer and it's small.
