As far as I can tell, building a similar system using NVMe is vastly more complicated. If you can fit everything into M.2 slots, it’s easy. Otherwise you need barely-standardized PCIe cards, backplanes, connectors ordered off a menu of enterprise things with bizarre model numbers, and possibly “RAID” cards even though you don’t actually want hardware RAID.
- zekica 4y agoYou can use pcie switches on pcie x4 to 4xM.2x4 drives.

- loeg 4y agoThe active pcie switches are a lot more expensive than the passive splitters that only work on systems with pcie bifurcation.
- amluto 4y agoFor a large scale storage system (more NVMe devices than PCIe lanes), a switch is mandatory. Or a “RAID” card or another switch-like device.

- fomine3 4y agoNowadays some recent consumer platforms supports PCIe x16 to x4/x4/x4/x4 bifurcation that should be enough. For RAID, switching (dynamically shares bandwidth between SSDs) is nonsense, isn't it?
- jandrese 4y ago22TB of NVMe drives is going to be a bit more expensive than the system in the article however. I do wonder what the power consumption figures would be though. His system was drawing an annoyingly large amount of power and I suspect that was mostly those HDDs.
