Why would you expect that a modern 8-core Intel CPU would impede I/O in any measureable way as compared to the outdated single-core 32-bit RISC CPU typically found on hardware RAID cards? These are the same CPUs, mind, that regularly crunch through TLS 1.3 on line-rate fiber Ethernet links, a much tougher task than mediating spinning disk I/O. > And where > do you get cost-efficient cards that can do JBOD? $69, 8 SATA/SAS ports: https://www.newegg.com/p/0ZK-08UH-0GWZ1 Search for “LSI JBOD” for tons more options. You may have to fiddle with the firmware to get it to stop trying to do clever RAID stuff, which lets you do smart RAID stuff like ZFS instead. > What has HP been thinking?
