Seagate Cheetah 10K.6 = Cheetah 10K.
U6 (yes,
that U6)
From a company whose 7200rpm (S)ATA drives of the time remain probably the most reliable HDDs
ever made to this day (regardless of cost or specifications), you'd have expected more effort than
this – at the very least they could have used FDBs (already standard in the Barracuda ATA IV a year prior) rather than hanging onto BBs until the bitter end. I could forgive the resultant outer-zone crash if the drive ran for
10 years, but 5.3 years is nowhere near enough margin for comfort.
Besides the bearings, you can see there that the 10K.6 also has an aluminium voice-coil, bare copper lands on the PCB, and a crude pressed-on spindle clamp.
The Barracuda ATA IV and V have a copper voice-coil, HASL-finished PCB (with impeccable soldering
) and a 6-screw spindle clamp.
(Anyway the 10K.6 shown appears to have lead-free solder – but the Barracudas were durable enough to
deserve leaded solder; the 10K.6 wasn't.)
If the pun wasn't enough of a hint – it's sad to say, but I think the Cheetah 10K.6 was no more reliable than the U Series
(And at least the U6 drives died peacefully by media degradation, rather than their heads crashing on the platters wobbling on knackered bearings…)
Then again, maybe Seagate used their extra profits from the 10K.6 to fund the build quality of the Barracudas
I'll give it to Topcat too – he was probably right that Fujitsu made the best SCSI drives.
