So say its makers, anyway.
That maximum read speed?
7450MB/s for Samsung, 7300MB/s for WD.
Write speeds also appear to favour the 990 Pro, with a claimed 6900MB/s to the Black SN850Xs 6300MB/s.
And why not PCIe 5.0SSDs are still a ways off.
The latter won out on sequential write speeds too, with the 990 Pro producing 5349MB/s.
Thats otherwise excellent, but not as high as the SN850Xs 5701MB/s.
All that hype for nowt, then?
In CrystalDiskMarks random 4K benchmark, the Black SN850X recorded a 3187MB/s read speed.
Games are almost all about reads, and the 990 Pro is successfully superlative for them.
A2TB Black SN850Xcosts, in the UK, the same as a 1TB 990 Pro.
In the future, mind you, Id expect the decision to get much tougher.
