Where reviewers disagree No direct contradiction. Emphasis differs: StorageReview frames performance as roughly on par with the Samsung T7 Shield and SanDisk Extreme V2 (pick on other factors like size), while PCWorld stresses the X9 Pro clearly led its 10Gbps peers in real-world file copies.

Blackmagic sequential read (2TB): 957.9 MB/s · Blackmagic sequential write (2TB): 901.7 MB/s · IOMeter 1-thread 2MB sequential read: 873.5 MB/s · IOMeter 1-thread 2MB sequential write: 803.3 MB/s · IOMeter 4-thread 2MB sequential read: 1,039.2 MB/s · IOMeter 4-thread 2MB sequential write: 975.5 MB/s · IOMeter 4-thread random 4K write: 65,700 IOPS · IOMeter 4-thread random 4K read: 15,278 IOPS
The Crucial X9 Pro Portable SSD (2TB) recorded 957.9MB/s read and 901.7MB/s write, which is a bit under what Crucial quoted, but this is a single-threaded test that won't push the drive to its full capabilities.
The Crucial X9 Pro is by far the smallest and lightest drive.
When it comes to the Crucial X9 Pro specifically, it's a strong contender and should be a popular companion for enthusiasts who appreciate the tiny size and lightweight profile.
Marrying good looks, great performance, and affordability, the X9 Pro is one of the top 10Gbps USB SSDs on the market.
Where the X9 Pro really shone was in the 48GB transfers, easily outpacing both 10Gbps competitors.
The X9 Pro didn't place first in the synthetic benchmarks (CrystalDiskMark 8/AS SSD), but it wasn't far off, and led the 10Gbps pack in our real-world 48GB and 450GB transfers.
