May 21, 20206 yr Hi all - I am looking to build a new UnRAID Plex server soon. The purpose of it is to host a Plex media server. Easy enough. The storage disks will be 5400 RPM. I am wondering if I should spring for my parity drives to be a bit faster in the event of a parity rebuild. Would it help with the speed of the rebuild effort, or does it just not matter?

Would it help with the speed of the rebuild effort, or does it just not matter? The write speed will be dictated by the slowest disks that are accessed during writes. And since parity disk(s) are always accessed during writes, the general recommendation is to use the fastest disks you have in the array as the parity disk(s). Edited May 21, 20206 yr by Phoenix Down

All the remaining drives must be accurately read to recreate the missing disk, not just the parity drive. The rebuild will be limited by the read speed of the slowest drive / interface in the parity protected array.
