If the drive part of a RAID setup I would actually prefer it just reports itself failed and doesn't slow down access to the array by scanning itself for 20 minutes.

As far as I know, that is one of the main differences when buying enterprise or nas drives compared to consumer drives. With nas drives, the firmware gives up very quickly since the drive is assumed to be part of an array with redundancy. Consumer drives will retry reads for a very long time before reporting i/o error.

Potato, potato. If your array doesn't kick out a drive that stalls for 30 seconds, much less 20 minutes, why not?
