...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? That the hardware vs software RAID argument is over in 2020.

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. I?m sure you can reflash LSI card to make it SATA or SAS HBA, or MegaRAD hardware RAID...

...Once you start throwing ~5 ms seek times into the mix, the CPU?s job becomes even easier.
