Samsung 9100 Pro review: a fantastic option for professional use, but not for gamers

Samsung 9100 Pro: Two-minute review

It’s very hard to say that a drive that sequentially reads nearly 12,500MB a second doesn’t live up to expectations, especially not when its performance everywhere else is better than anything else I’ve tested, but that sticker on the box of the Samsung 9100 Pro that promises up to 14,800MB/s sticks in the craw of an otherwise perfect M.2 PCIe 5.0 SSD.

Starting at $199.99 for a 1TB capacity drive (about £155/AU$315), the 9100 Pro is Samsung’s first ‘true’ PCIe 5.0 SSD after the Samsung 990 EVO and Samsung 990 EVO Plus. Both those drives are PCIe 5.0, but they only use two PCIe 5.0 lanes, which limits their practical speeds to PCIe 4.0 standards.

The 9100 Pro, meanwhile, is a full-fat PCIe 5.0 x4 M.2 drive, meaning its theoretical max speed for sequential reads is upwards of roughly 15,000MB/s and 14,000MB/s for sequential writes (this number has been edging up over the past 3-5 years, so take that theoretical maximum with a grain of salt at this point).

Samsung promises that its latest drive can hit up to 14,800MB/s sequential read and 13,400MB/s sequential write, and the Samsung 9100 Pro gets there somewhat. It clocks in a max sequential write rate of 13,066MB/s in my testing, but the 9100 Pro’s maximum sequential read speed only hit 12,427MB/s. This is still incredibly fast—but, it’s not what’s promised on the box.
