Quick follow up: the problem was either the PSU or a sata power cable splitter. I replaced both and everything started humming along nicely but didn't bother to troubleshoot whether it was the PSU or the cable. Thanks for your help itimpi!

Well it passed the extended SMART test with flying colors and the DiskSpeed docker clocked it at 210MB/s once the parity check was canceled. With parity check running it didn't benchmark at all. I've been concerned that, like Icarus, I've been flying too close to the PSU's upper limit ( (it's 550 watt and there are 8 hard drives and one SSD) so I guess I need to beef up my PSU or consolidate to fewer, larger disks. It hasn't been an issue before but I did add another 12TB disk back in October so this must have been the first parity check since I added that new disk and now I'm seeing issues with all the disks running simultaneously. Although, I did just put all my parts into PCpartpicker and it's estimating around 330 watts. Needing more than 550 watts for less than 10 drives does seem like a bit much to me. Am I underestimating power consumption you think? Thank you again for all your help!

Well dang. I was thinking it was only a couple years old but it's actually been in service for 4 years now so I guess I shouldn't be too surprised. Thanks for your help!

Hello, I run parity checks quarterly and this last one has been super slow and causes an occasional squeak sort of noise every couple minutes. I assume a disk is dying but I'm not sure where in the diagnostics to look for the relevant info. Would anyone be kind enough to look at the diagnostics or let me know where to look?
