Not so. fsck does relatively few writes -- it tries to keep the amount of change to a minimum, though the change will be scattered across eraseblocks and thus have a horrible write amplification. What it does is a *lot* of seeking, which is nearly instantaneous on flash.

Oh god. If it's repeatedly rerunning fsck in the blind hope that maybe it'll work if it keeps trying enough, that might explain it.

The reason you don't see this situation with the SSD in your (whatever) other device is because it is hidden by the controller inside of the device.
The micro-controller in an SSD is much more "intelligent" than that of an eMMC device.
Good point. (Though I'm not the person who had the problem, I'm just a curious bystander who knows how e2fsck works.)
