As WD brilliantly fucked up their WD-Red series and made a real mess there with SMR and some labeling stuff, I decided to go for Seagates IronWolf Pro disks to expand my […]

As long as only one disk breaks down, it is still functional – even while rebuilding. To do the recovery, we need to locate the bad disk, […]
