I have been searching and learning a bunch but there doesn’t really seem to be any good methods that I can find.

You would think more companies would be putting out DAS considering the capabilities of USB3.2 and Thunderbolt. I have been looking for a quality DAS but almost all of them don’t have built in hardware RAID. I don’t really trust software RAID. Mostly rebuilding if the software crashes or my hardware crashes. Even if I was ok going with soft RAID, almost every model has a huge flaw.

It feels like getting a NAS is the only real way to go and basically just using it as an ethernet DAS for my server. It just seems like a waste of a processor. Should I just build a DAS with 4 Bay Rack? Then I have to find a place to mount a PSU and tidy up one of those PCIe to 4 Sata boards and PCIe to USB board as well as a couple fans.

Is there a good cheap enclosure to just install 4 HDD, a couple boards and a PSU? Am I missing some other easy option? It just feels like the market now is to buy a NAS and use it as a DAS.
