The main thing is: why going with all the “troubles” (mainly controller and PCB routing for signal integrity) for making a PCIe 4.0 drive with the performance of a 3.0 one?The controller dictates whether it's a PCIe 3.0 or 4.0 drive. @Maxx confirms that WD are using a Phison E19T controller rather than their usual Marvell controller, possibly due to supply issues with the Marvell ones.
The pricing seems to be in line with similar-performing PCIe 3.0 drives, and a PCIe 4.0 drive can work in a PCIe 3.0 slot without any problems so why worry about it - 3600MB/s reads are very slightly higher than the ~3500MB/s reads that PCIe 3.0 tops out at. It's not much of an increase, but why reject free performance increases if they don't have any other downsides?
Also, is it me or this SSD “smells” like it has a 4.0 x2 link, which means that in a 3.0 mobo it’s capped at about ~1700mb/s (not very slow, especially compared to SATA drives)? Of course, from an user POV, it doesn’t matter in 99% of cases, and I can confirm that because I switched from a PCIe 3.0 platform (2700x, X470, 8200 pro 1tb) to a 4.0 one (5600x, B550, SN850 1tb) and it didn’t speed up any game level loading where the hugely better ST score of my new CPU isn’t helpful at all.
Also, I didn’t need to upgrade to a 4.0 drive, but I sold it for a great price along with the rest of my parts as the beginning of a 2-phase modernization of my rig, since newer games will benefit from a super speedy drive (DirectStorage), even if they’ll work just fine with a 3.0 one.
