I think so. There are four dead drives sitting in a stack at the colo and I have one here from November last year. I bought both machines the previous July, so these so-called Enterprise drives started failing after 16 months of operation. I swapped the whole SAS array out for SATA on the one machine in February, and when we run out of spares (4 left) for this machine, I might decide to swap the whole array to SATA as well. Now that SAS drives are back to $160 a drive rather than the $500 they were in January, we might buy a couple more spares instead.
