To add some more information to an excellent summary, in the realm of
Non-Recoverable Error Rates (NRER, a measure of how often the drive gets
it wrong while reading data), enterprise class SCSI drives are at least
an order of magnitude better than most anything else out there. Back to
my previous examples, the Seagate ST3146854LC SCSI drive has a NRER of 1
in 10^15, while the Western Digital WD1600YS (Enterprise level server
drive ) has a NRER of 1 in 10^14. The WD Raptor line claims 1 in 10^15.
I've seen those numbers a couple of times, but what do they *mean*?
10^15 bits is approximately 10^14 bytes. That's 100GB.
A simple dd from a 100GB drive to another should throw a non-recoverable
error.
Is that actually true? If so, I need to bring ZFS online on every drive
I own immediately.
