Customer Ratings & Reviews

Massive external storage that's not much larger than a deck of cards. Super easy to use, just plug and play via USB. Use it to offload storage from your phone, GoPro, whatever you can connect to. Really reasonable price per TB and SanDisk quality and reputation, so you can't go wrong.

Solid and BIG i transfer files to this constantly and its build has withstood alot of travel.

It's easy to connect to your laptop, but my only complaint is that it's not actually 4tb. It's actually 3.6 tb. I got this on black Friday for $229, so I can't complain too much.

I am currently using this as an external drive on my Lenovo laptop. It has a copy of the backups from my husband's 3 computers, as well as the files from my file scanning program (liken it to having my file cabinet contained in that little drive), as well as files from my genealogy programs. What is very nice is that it doesn't matter which computer I am on, I can still access the files that I need.

I love this hard disk and it's fast and it's good price.

These things are great. I have 4 of them already. I often run editing projects off of these SSD's.

Great portable SSD. I have been using it with a PlayStation 5 to play PS4 games. No problems whatsoever. I have not tested the read/write speeds on PC but if you want a fast solution for your PlayStation 4 games, one of the best options.

Truly a plug and play product for me. I'm using this drive as a backup and found that the files I was backing up daily were large and the regular HDD was too slow. I thought I'd give this SDD a try and it makes it possible to duplicate the files on another PC without using the cloud.

I recently purchased the SanDisk Extreme Portable 4TB External USB-C NVMe SSD, and I am absolutely thrilled with its performance and reliability. This external drive has exceeded my expectations in every way, and I can confidently say that it outperforms most other options in its class.

Easy to use, quick transfer speeds, very light, convenient size

I have been using this for about a month or two, and it has been working as advertise. Using it to store games has saved a ton of space on my laptop and the loading times are fast, which is an important factor when storing games off an external storage. Overall, very solid product!

bought this for my large files including photos fom my computer

Smaller than I expected for 4TB! It's slower than I thought on my desktop with USB 2.0. I thought I'd get better speeds. Faster on my laptop with USB 3.0. Kind of feels like cheap plastic so I'm extra careful with it. What I noticed is that when I first boot up, it's slow to be recognized by the PC. I have experienced some lag.

Compact size with 4 TB maximum capasity, but data transfer is slower then normal. It fits mach easier in any pocket because it's much smaller then other 4TB drives, but it took about twice as long to load 3TB of data then other external drives I have. Good for daily use, but there cheaper and faster options for backups.

great hard drive. quick transfers and uploads. saves time.

I was able to catch it on sale for 200 dollars off which made it very worth it I’m a photographer so I store all my images else where the regular price of this is pretty pricey but if you’re able to catch this on sale I suggest you get it if you need more storage

Great product and the speed in which it down loads be files is amazing...

This is a fast little device. Just keep in mind that you have to unsave your password to save the annoyance of signing in every time you power up your computer. Otherwise, the device will be locked until you enter the password.

Can't beat the size with so much memory. Very portable!

Small and functions well. Nice to have the extra space and easy to carry around.
