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

Realistically, something like ZFS or a RAID-6 with extra hot spares would help reduce the risks, but it’s still a non trivial amount of time. Not to mention the impact to normal usage during that time period.

Network? Nah, the bottleneck is always going to be the drive itself. Storage networks might pass absurd numbers of Gbps, but ideally you’d be resilvering from a drive on the same backplane, and SAS-4 tops out at 24 Gbps, but there’s no way you’re going to hit that write speed on a single drive. The fastest retail drives don’t do more than ~2 Gbps. Even the Seagate Mach.2 only does around twice that due to having two head actuators.
