Customer Ratings & Reviews

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

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.

Its crazy how much the Form Factor has shrunk in the matter of a few years. This is the size of an AirTag almost! No issue with Transfer Speeds either

This drive was a pleasant surprise. I have been using another popular brand, but some certificates and sale pricing made this a no-brainer. The size is very compact, and the handy cut-out/access light on the corner could make for a spot to put a strap or tether to keep it attached. The speeds are right where they're advertised to be, but that is all dependent on your device's USB port speed, as well as the proper cable being used. All in all, a great value for a 4TB ultra portable SSD.

A lot of storage in a all space, i have it connected as a supplemental drive every day for a year with my usb hub with all my other external drives. Havent lost any data yet so i cinsider it a reliable devoce tgat i am able to trust more over m external hdd's.

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.

Great and super fast SSD. Super compact, great for traveling and on the go storage

Super small but super fast and reliable for the price

It loads quickly, transfers files fast between the computer hard drive and external SSD, and opens/loads individual files quickly too. I do have an issue often when I want to eject the SSD before unplugging it where it will say it's in use, but all files and apps are closed, but I can't figure out what is running and preventing it from ejecting properly.

Bought for being able to record a solid amount of ProRes content, 4 TB more than enough, easy to use and very compact.

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!

Works great. Fast. Small enough to travel with. It replaced my last non-SSD. Great sale price.

Fast, durable, reliable and all in one small package!! I love it!

I’ve use just about every major brand of portable SSD USB drives and this one rocks!!! Small, has a hook hole, rugged and fast! Bought two since they were on sale.

I purchaced this to assist in reimaging some mini-PC's. Very fast, and convenient USB-C SSD.

I have used external SSDs for years now. The X9 Pro is an excellent choice that writes and reads fast while offering reliable storage at a great price. I have now bought this drive multiple times!

Nice and fast, great little drive very portable. I highly recommend it.

I can't believe how small a 4TB drive can be nowadays. Great for transferring large files and taking them on the go.

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.
