Sustained sequential write (first ~11 min, Iometer): 1750-1780 MB/s · Sustained write after cache saturation (Iometer): ~1400 MB/s

Crucial's X10 Pro is the fastest 20Gb/s SSD we've tested.

It hovered mostly between 1750 and 1780 MB/s for just over 11 minutes, before dropping down to the 1400 MB/s range, which is still faster than the vast majority of competing drives at their fastest write speed.

20Gb/s USB (3.2 Gen 2 2x2) ports are pretty rare

Blackmagic Disk Speed Test (write / read): 1,564.0 MB/s / 1,723.1 MB/s · IOMeter 4-thread Seq 2MB read: 1,966.9 MB/s · IOMeter 4-thread Seq 2MB write: 1,736.2 MB/s · IOMeter 4-thread Random 4K write: 67,206 IOPS

The Crucial X10 Pro Portable SSD (2TB) recorded 1564MB/s read and 1723MB/s write. This is under what crucial quoted, which was up to 2100 MB/s read and 2000MB/s write.

the X10 Pro loses against the other Gen2x2 SSDs in both the read and write metrics. It doesn't lose by a lot, but it's still a difference worth mentioning.

we're big fans of what Crucial has done with the X10 Pro and give it our recommendation.

Sustained write after native TLC (~900GB written twice): 50 MBps

While the X10 Pro didn't blow our socks off in the synthetic benchmarks, it was truly excellent in our real-world testing–beating two Thunderbolt 3 competitors in the 48GB transfers.

the results were rather dismal once it went south–50MBps.

Random ops are not the X10 Pro's forte
