Customer Ratings & Reviews

Works great! Small; little. Huge storage. It’s the size of a credit card!

This is slightly thicker than the 2TB External version that I also own and not notably heavier. It allows me to carry my files all in one place. Being able to carry 4TB around in my pocket is great. And I was able to use my accumulated Best Buy VISA reward points to significantly reduce the price.

After using smaller Extreme portable SSDs as MacBook Time Machine drives (one at home, and one in the office, hanging off a USB-C port on my Thunderbolt dock) for some time, I upgraded to a larger MacBook and needed more space. I looked at a larger Extreme briefly, but decided to go for the Pro instead to get the 2 GB/second speed and wow, was it ever worth it. Backing up and restoring large files are now lightning-quick. I get full speed when I connect it directly to the USB-C port on my MacBook. My dock will only do 1 GB/sec, but because it's in the background, for convenience, it works out rather well. I can always move the drive back to a direct connect port to get full speed again. The bottom line is this: I trust SanDisk to do solid-state storage. I've had problems with every other big brand. SanDisk has never let me down.

I am always a fan of SanDisk, they are reliable, fast and powerful. This drive has read/writes speeds of 2000 and that is amazing.

The speed and capacity is perfect to supplement my Mac Mini.

Rugged design .. fast accessible storage .. I even edit from these units .. superb performance

This is a big upgraded from my old external hard drive. Having the USB-C really makes a difference when it comes to loading any kind of files and I do use it for DJing so it’s also super fast on that end.

Fast and so small! Honestly i want to commend the person who helped me find it though. He was fast, his computer work was great and it was a very easy transaction.

Absolutely the perfect drive, portable and fast. I now own 5 of them.

The SanDisk Extreme Portable 4TB External USB-C NVMe SSD is an awesome. Good price, good product, well packaged. I already had 4TB external drives from Best Buy. This is the third one.

Excellent external drive! The 4TB drive is large enough to back up all my data and it is much faster than the mechanical hard drive I had been using.

I got these to go with my playstation 5, as well as my xbox series x and these things fit in half of the palm of my hand and are as thin as a kitkat! Yet sure as can be they hold 4tb! Man how technology sure has advanced! Lol

Has been in use about a month. No troubles whatsoever. Superfast for accepting large files and folders, as well as spitting them back out again/

Very fast ssd and it’s very portable fits in your pocket. Make sure you have a usb-c plug on your PC to take advantage of the faster speeds usb 3.0 is not as fast as usb-c.

Fast and simple, perfectly designed, it is even so nice just to hold it in you hands. I use it for streaming videos, no difference with real live TV. Keep in mind its 4 Gb capacity.

This hard drive is very useful. I bought it for use in an Apple computer. Its speed is very fast, which is beyond my expectation. If its price is better, I will consider buying another one. However, it also has a disadvantage, that is, it does not provide you with a box to protect it, which makes you have to buy a box separately for it.

I’ve been using this Samsung 4 TB SSD as a backup drive and to transfer large files, and have been very impressed with its speed and small, durable form factor. There are certainly less expensive alternatives; however, I bought it for around $300 which still feels expensive, but I have been very happy with this purchase so far.

Expensive but works. Using for backup drive for another SanDisk 2TB and my computer. Easy to format for my needs.

This works as well as the other SanDisk that I own. The only problem or issue that I have is that the disk gets extremely warm or hot if a lot of data is being transferred.

Love it, really fast, light and does the job. Wish it was a bit more budget friendly.
