The focused drives have been made by six producers, together with Western Digital, Hitachi, Seagate, Toshiba, Samsung, and Maxtor.
Safe Knowledge Restoration additionally discovered that the common anticipated lifespan of a failed arduous drive extremely relied on the drive producer. In keeping with a power-on-hour chart it created, there’s virtually a 50% distinction in power-on time between the very best and worst-performing manufacturers.
Toshiba carried out the very best, with a mean of 34,799 power-on hours recorded between 151 unhealthy drives. Conversely, Hitatchi – a WD sub-brand, was far worse, with a mean recorded lifespan of 18,632 hours gathered from 211 unhealthy drives.
