This is the latest version of the SN850 series. The SN850X has a faster read/write/iops than the regular SN850. Simple install, but no screws with the kit. WD app is very informative and is also used to control the small rgb lighting. The rgb is tiny and does not get very bright. The heatsink is thick with air channels. I like the thermal pads are placement. Works at advertised speeds and is lightning quick. It looks nice with an exposed chassis. This is one of the fastest nvme storage drives on the market.

I upgraded to the 2 TB SN850X from a same-sized PCIe 3.0 SSD from another vendor that used QLC flash. I thought that any modern SSD is fast enough by any reasonable standard, but I actually noticed a big difference launching programs, installing games, and transferring files to/from my NAS. My old drive would get bogged down and show high latency in Task Manager, while this model blows through everything. The heatsink is nice since I’ve had issues getting 3rd party heatsinks to attach securely and stay attached, their elastics would melt over time with heat. That said, I had to remove the motherboard’s included heatsink and do some mechanical finagling.

The drive was slow, and it does not work well with the standard Windows 11 22H2 driver. I wish I could send it back. I would get a lot of raid0 warnings, even though I was not running raid. Went back to my WD 810 that came with the laptop and my benchmark scores went Up not down, and no more warnings. Any one want to buy my 850x for a cheep price?

This thing was really easy to install (although I did have to order an extra screw because the one that comes provided for use in the PS5 was stuck). This thing is super fast going from PS5>SSD, going the other way though it is slower, maybe 2-4 times slower.
