"Seagate has a history of making cheap drives with a low mtbf. "
Maybe recent history? Check out how many 15-20 year old functional Seagate SCSI drives are on eBay and selling for ~$5-20+ per GB!
Right now I see,
ST52160N, 2GB, $132 [$66/GB]
ST32151N, 2GB, $95 [$47]
ST51080N, 1GB, $45 [$45]
ST34520N, 4GB, $175 [$44]
ST34520N, 4GB, $150 [$37]
ST32272N, 2GB, $72 [$36]
ST51080N, 1GB, $35 [$35]
ST31051N, 1GB, $33 [$33]
ST32272N, 2GB, $65 [$32]
ST34520N, 4GB, $119 [$30]
ST39140N, 9GB, $190 [$21]
ST32550N, 2GB, $30 [$15]
These aren't listed prices from crazy sellers, these are SOLD items. Seagate must have been doing something right in the past when their USED drives from the 90s are are still selling for the kinds of prices that brand new drives sell for now that have 1000x the capacity [and are much faster, I think these 50-pin SCSI drives top out at ~10 MB/s].
