I guess those are 500 GB? My smaller ST3160023A has "3 years, 4 months,

I don't know how long I ran a some 200G Seagates. One SATA and a PATA
are left out of possibly three maybe four original units. I've backup
data the PATA, at least while MBs continue to provide the interface;-
same for the SATA, which is among storage drives that don't see a lot
of use, except for a powered USB docking stations. It's almost
ludicrous to admit a preferred efficiency I still like about my first
SSD, a Samsung 64G unit. My last 500- to 700G-class, a plattered
Western Digital HDD, though, still bears a brunt of downloadable
material, augmented by a couple other 250G-class SSDs, and organized
accordingingly for strategical advancement a SSD provides. The WD
will be next to go, placed in the dockting-station queue and replaced
by a 500-class SDD.

Another thing comes to mind, re the OP and Statistical Abstracts
provided by IT WEB "drive rankings". HDD manufacturers are neither
unaware of an unfavorable such publicity provides. At times farther
research is indicated, e.g. a HDD manufacturer model may be
subsequently "hidden", as an identifiable model, within and subject to
objectionable characteristics. Another area is updated drive firmware
ROM. One of my 2T drives was manufactured to cycle-out power states
inordinately. Jacking the power cycles, thereby shortening a drive
life span means. . .who needs integrity when spending more of your
money on failed drive replacements is vastly more interesting. The
manufacturer subsequently released a firmware patch to define a
definable maximum for nonintervention of data polling. The firmware
was a direct result from a class action lawsuit against the
manufacturer by the IT sector.
