Samsung's sn850x vs 990 pro is one of the most powerful mvme 4.0 drives you can buy today. This drive aims to combine performance with power efficiency and thermal management so that it can be used in laptops, PS5, as well as high-end desktops. It also offers some of the fastest random read and write speeds on the market.
It has some serious competition on the market, though. The Seagate FireCuda 530 and SK hynix Platinum P41 offer similar speeds but at lower price points. In AS SSD's sequential benchmarks, the 990 Pro fell short of its claimed maximum read speeds. However, it was able to match its competitors in random 4K and sequential writes tests.
In 3DMark's storage benchmark, the 990 Pro delivered some of the best results we've ever seen. This is thanks to its faster write speeds, which are a lot more useful for games than the 900x's higher sequential read results. It was even able to beat the Black SN850X in our gaming-focused PCMark 10 trace-based benchmark, although it couldn't quite match the WD's Full Power Mode.
All in all, the 990 Pro is an excellent option for those looking for the best PCIe 4.0 SSD around. It's not the cheapest drive you can get, but it should be significantly cheaper than the premium prices WD and SK hynix were charging at launch. And if you can catch the 990 Pro on sale, you'll be getting it at a much more reasonable price than its competitors.
