Though OP is using RAID-10 not RAID-1, and with more than 2 devices IIRC. OP wants to check the performance and I agree they should do that for both the normal case and the degraded case, but what are we expecting *in theory*? For RAID-10 on 4 devices we wouldn't expect much performance hit would we? Since a read is striped across 2 devices and there's a mirror of each so it'll read from the good half of the mirror for each read IO. -- https://bitfolk.com/ -- No-nonsense VPS hosting
