Ah, the RAID array love story: one of many similar disks fails, you replace it, array starts rebuilding which causes an increase of reads from other drives and before rebuild is complete, more disks from the same batch start failing.

I don't deal with storage hardware much for some 6+ years, since I've switched to cloudy solutions. But at the beginning of my shared storage building journey, I considered arrays built from different disks somewhat "lame" or "unprofessional". I changed this viewpoint 180° after seeing multiple similar drives fail in a very short (hours, days) timespan for the second time.

I now have more trust for home-built ZFS setup using different disks than a dedicated storage appliance using enterprise-grade disks with almost following serial numbers.
