My three GP's (all 1TB, two first generation 00ZJB0 (4-platter) and one second generation 00D6B0 (3-platter)) are still working fine. Unload cycle counts are as follows:
GP #1: 0x873F7 = 553975 cycles, 0x2716 = 10006 hours
GP #2: 0x54189 = 344457 cycles, 0x2325 = 8997 hours
GP #3: hidden ("0x4C"), 0x1516 = 5398 hours
Bad sectors on all HDDs = zero. (No reallocated, no events, no pending, no uncorrectable, no other errors in SMART. All pass offline test and extended self-test. No Windows Event Viewer errors.)
Samsungs... well, they don't have unload count issues.
F1 7200rpm #1:
OS drive, just recently one uncorrectable sector appeared. Some odd crashes (but might be unrelated as well). Offline datacollection routine fails with fatal error. But now the uncorrectable sector disappeared... odd. And it's NOT displayed as reallocated either.
Very low vibration sample.
F1 7200rpm #2:
High/medium vibration sample. "Retired" to Topfield PVR because it made my computer case resonate.
Flaky sequantial transfer rates from the first verify pass. No problems with offline datacollection or SMART selftests. It's just read or verify passes that are jagged. Disabling indexing helped a lot but there's still downward spikes on the same areas, just not as big as indexing turned on.
Speed (outside these downward spikes) is equal to that of F1 7200rpm. 105 MB/s from a 5400rpm drive. 500GB platters are wheeee~. And with only 2 of them at low rpm, it's quieter than my 3 and 4 platter (250GB or 333GB per platter) GreenPowers. Noise character is also smoother.
But, I still feel a LOT
more confident with my WDs. Samsungs tend to die in VERY odd ways. This uncorrectable error stuff is odd. Why don't they ever reallocate? Always the friggin' uncorrectables and bad sectors always visible to OS level. Or maybe the reallocated sectors are just hidden from SMART (despite the attribute being still present even though unused). Samsungs scare the shit out of me. If I have to decide whether I like to have hidden bad sectors or hidden unload counts in my SMART reports, I pick the latter any day.
I think the GP issue is way blown out of proportion. Trying to reduce cycles is wise (i.e re-configure SpeedFan to disable tempeture monitoring on GreenPower HDDs) but to boycott the drive and favour other manufacturers (with their own, bigger reliability issues) is just plain stupid. If you pick Samsung because it's cheaper, you're just curious, because you're unsure what density will the 1TB WD be (as we may never know when they go from 3 to 2 platters), they are all valid reasons (and they ALL
played a role why I bought F2 EcoGreen) but I would definitely not favour Samsung (let alone a noisy and potentially firmware suicidal Seagate) over WD due to reliability concerns.
