It's really hard to find decent SSDs, even in the datacenter space. We've had 3 generations of Micron SSDs that, with the default settings, will cause data loss. Micron support is very friendly and competent right up to the point where you point out the bugs in the SSD firmware.
At home I've had good success with Samsung SSDs (EVO, Pro and the OEM PMxxxx) and recently with WD black and blue models, even though WD owns SanDisk (or vice versa).
If you're hooking up the SSDs over thunderbolt to MacOS, do a bit of research to see which SSDs play nice. One of the big differences between MacOS and windows/linux is that Apple doesn't support Host Memory Buffer. That's a 'feature' where the OS uses its RAM as cache for those DRAMless SSDs. Those include pretty much all m.2x30 and m.2x42 drives and virtually any drive cheaper than the matching Samsung model.
