Customer Ratings & Reviews

Speedy, solid and amazingly tiny. I can carry this in my pocket to my presentations, with all my documents, videos, clips, and presentations easily at hand...with room to spare (both on the disk and in my pocket :))

Definitely good transfer speed. Even smaller and lighter than I expected. Easy to throw in my bag everyday.

This external SSD is a fantastic combination of size, ample storage space, and transfer speed! I did several speed tests and large media file transfers and I will definitely use this for image and video asset management. Buy it!

Absolutely works perfectly for my laptop games it downloaded them at lightning speed and helps them run quite smoothly!

I use it for DJing to store music. I got 300,000 songs on it loads pretty fast and very compact lightweight and very durable.

The Crucial-X9 is the smallest and most compact 4tb solution I have found (be careful not to lose it in the bottom of your bag). Performance is excellent, and it is extremely fast Time Machine backup for your MacBook or large file storage needs.

It is smaller than I expected. I have a 4TB HDD, that is 64 times bigger in physical size, than this 4TB SSD. It is fast and comes with a USB cable.

This is my first SSD external that I’ve purchased. My external hardrive was starting to slow down so I bought this one to transfer everything to. Once transferred, wow! It is so fast! I won’t be going back to hard drives.

I use mine for maintaining Timemachine backups for my MacBook Pro. The drive is blazing fast compared to a traditional external HDD. Seems reliable. Very portable.

Fast read and write speed. I have 2 of the same ones and this is my THIRD one! Very reliable and compact! Great product!

I was suprised by the size. It’s small. I’m using it for a song backup for a karaoke system.

Works as expected. Tiny in size but great in capacity. Has been rock solid so far.

It's very stable, no issues. Even the speed is pretty good. A perfect go to SSD for the storage

Fast, compact & economically priced. Prefect for handling large amounts of data such as professional video footage.

Very nice little external drive! But don’t let its diminutive size fool you. This 4 TB drive is fast and so far reliable. I am running this on my Mac Mini so it’s already formatted for XFat which is great because I am backing up stuff from old PC internal and external drives. The Crucial mighty small drive will R/W Mac and PC. Got this on a sale day that makes this an even greater value. I very much like and recommend this little external SSD drive to anyone needing a fast drive with massive storage 4TB.

Love the size and speed of this ssd. Can't beat the 4 TB of space as well. Part of my EDC kit. USB-C cable provided.

This thing is amazing. I kept running out of space and this one is quiet and I can keep adding to it. Great for a graphics and video editor.

I take this with me everywhere I go and dump tons of pictures and videos onto it. The transfer speeds are nice, it took only a couple of hours to transfer over 1.5 TBs of data from this to my PC.

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!

The X9 Pro External drive enabled me to backup my entire hard drive.
