Acer FA200 vs Western Digital WD Black SN850X: which one fits your build
Take the Acer FA200 for gamers and general users wanting 2000 GB of PCIe 4.0 storage at high read speeds. The same goes for buyers who value a 5 year warranty and a 1000 TBW rating. It is the wrong buy for workloads with constant heavy writing, since the NAND is QLC and the drive has no DRAM. Take the Western Digital WD Black SN850X for PlayStation 5 owners specifically wanting a drive engineered around that console's exact requirements. This is a genuine, specific strength independently confirmed across reviews. It is equally the pick for PC gaming builds on PCIe 4.0 wanting a strong, well-rounded alternative to Samsung's 990 PRO. Comparable performance with WD's own engineering approach. Avoid it for the most budget-conscious PCIe 4.0 buyers. The WD_BLACK SN770, covered elsewhere on this site, delivers solid gaming performance at a meaningfully lower price.
