Comment on Western Digital details 14-platter 3.5-inch HAMR HDD designs with 140 TB and beyond

  When you are running a server just to store files (a NAS) you generally set it up so multiple physical hard disks are joined together into an array so if one fails, none of the data is lost. You can replace a failed drive by taking it out and putting in a new working drive and then the system has to copy all of the data over from the other drives. This process can take many hours to run even with the 10-20 TB drive you get today, so doing the same thing with 140 TB drive would take days.

    @SmoothLiquidation @Telorand They also claim up to 8x speed improvements with HAMR. Obviously that remains to be seen, but if they could roughly match capacity improvements, that would keep restriping in the same ballpark.
