As part of repairing a disk failure, I'm replacing a single working 18TB disk with a new 22TB disk, and then re-using the 18TB disk to replace a dead 18TB disk in the big 11-disk RAIDZ-2 array.

Every time I do this after another year or three has passed, I appreciate Bianca and Garth's message about the danger of HD capacity increasing quadratically vs transfer speed increasing linearly...

1+ day just to copy the disk. (!)
