    Ok - so I needed a backup for my laptop. I wanted to go with an SSD external drive and did some research and found the Crucial X9 Pro! It is super fast - I was able to transfer all of my really big video files very quickly. The coolest thing about this drive is how small it is! I ordered the drive online and when it arrived I thought I had ordered the wrong drive. It is so so small - perfect to throw into my laptop bag and take up almost no space. Vet cool. Would totally recommend this amazing drive!

    Saw this one day and it was something I didnt know I needed. This offers good read write speeds and I got the 4TB version so it offers plenty of storage in such a small package. I recommend this for anyone who takes a lot of videos or photos and prefers not to fill up their phone or laptop while on the go.

    So i bought this to back up a bunch of stuff and i love it. Its small enough to fit in that little pocket in guy jeans that nobody seems to know what its for. Speed and size are awesome for the price. Pove how its rugged and not looking stupid in doing so.

    Quick and very compact yet has a very large capacity drive. Purchased at a very good price. To get the most value from the software must be obtained by registering online and going to different sections in order to obtain and use the software. It would be easier for it to already be in the drive although I understand they are offered by different companies.

    The Crucial X9 4 Tb portable drive is so small physically yet so big in terms of the data it holds. I am a photographer who goes on the road for extended periods, so I need a reliable ssd drive to hold my photos. This drive is fantastic and it is the size of a book of matches.

    Great little (and I do mean little) device. It shocked me how small it was. Which is great but just a heads up don’t expect it to sit on your desktop, if the cable you’re connecting it with is stiff, it will flop around.

    Great external SSD. I was able to transfer videos and pictured at the top speed from my laptop. I moved over 5 GB of date in like 5 seconds. Pretty awesome. I probably didn't need 4 TB, but i won't run out of space for years.

    Great product overall, and speeds are as advertised. However if using an adapter make sure it is a usb 3.2 adapter or you will not achieve the speeds as advertised
