Isn't this another reason to ditch hardware RAID controller cards entirely? To be honest - whenever possible, I use Linux's built-in md RAID1/5/6/10 instead of proprietary RAID solutions, and use Enterprise-grade SATA drives. This gives me: . An opensource implementation . Opensource convenient well-documented management tools (that work the same across multiple vendors' hardware) . Better reliability (if it fails - and in my experience it doesn't do-so nearly as frequently as HW RAID systems - I have all the tools to put the pieces back together again) . Good performance . Good flexibility and transparency (I can trivially move drives to other systems in a disaster recovery scenario etc.) . Lower power consumption (a bit) . Lower cost . Very good support, (for any drives which I care to attach to it) and the ability to talk to the developers directly, and even fix things myself (try doing that with most proprietary RAID implementations). Now I understand that you don't get the same write latency as with battery-backed RAID (and as a result this is the only hardware RAID which I ever specify) - I just wish that someone would produce a decent battery-backed PCIe RAM card, and then (with a bit more open source code) this restriction would be removed as well. So... looking on the bright side, some Gen 11 do support SATA and AHCI, so why not just ditch this proprietary stuff altogether?
