The Adaptec 6405 (4 Disks) / 6805 (8 Disks), note, without E at the end, works great out of the box. There are other more expensive, but this is good for it's price.Hello, all in the title, i'm sick of loosing hours trying to get hardware working with super outdated drivers (tech support not helping) so if anyone knows a raid card compatible with raid 6 AND that will work on fedora 23 please by all means share it.Price is not relevant, i can go up to 300euros/dollars if needed, i just want something that works for sure.
