Customer Ratings & Reviews

I have bought several of these. They are so reliable and comfortable to use.

This little unit serves my needs perfectly. I require a lot of external storage and a secondary drive from which I can run apps on my 256 GB Mac Mini M1. This and a couple others I now utilize have completely replaced external hard disk drives in my system. And, if needed to access files on these drives away from home on my 11" iPad Pro M1, a quick eject and I'm on my way. A perfect solution for me!

Fast drive, great performance, I have purchased several for use in recording studios!

I use this mostly to hold imagery from Summit and Stark counties (Ohio) which are large files to use for ArcGis Pro. Every time I move the map it has to regenerate. This can take a few seconds in some circumstances. But the SanDisk SSD is lightning fast! I am amazed how quickly the regeneration takes place. I use it for work and home. I don't see me ever buying an old style back up ever again!

Super-fast, loads of space, and the price was unbeatable (it was on sale for under $200)

Awesome portable memory. Crazy how you can fit 4th in such a tiny device

“After using the SanDisk SSD 4TB drive for a year, I can confidently say it’s been incredibly reliable. I’ve had no issues or crashes, making it perfect for storing large files and video editing. It’s definitely a solid investment.”

Great drive, holds all our files, easy to tote around in my backpack.

It can get hot during transfers and uploads but aside from that, its fast

A very solid drive that's easy to use and store. Great size!

very fast portable SSD. Use it for store photos and edit photos

I purchased this on sale, and it was a great price for a 4Tb SSD. For the full asking price, it is only a so-so bargain, but at almost 50%, you can't go wrong. I've used these extreme drives for a few years and find them to be very reliable and excellent compliments for a laptop when doing field phtogtraphy and image processing on locations.

Excellent drive, very fast, and reliable. This is my second one.

great drive super fast and easy and lightweight. essential!

Love the portability and size! All of this storage jampacked in such a small device. Love it.

This is what I have been looking for, a 4TB storage but in a very compacted, EZ to carry in my work bag.

fast and reliable and well compatible with my mac.

Very compact with excellent performance over usb-c, this drive has performed flawlessly for me.

Great compact hd that is super fast and durable! After using some previous models I will only use the san-disk!!

This is great!!! I am glad to have the high speed SSD to use for holding my Final Cut Pro video projects. I've been using a MacBook Pro M1 Max and moved all my video projects to this external. I haven't really had any latency. Full disclosure, I immediately reformatted the drive to APFS with no loss of space.
