Hi Hansmuff, ok if I have a reply-rant?
1) How different is a 75GXP from a 60GXP or a 120GXP? IBM has not said what causes the 75GXP drives to fail. The 60 and 120GXP drives incorporate components that have likely only evolved a little from the 75GXP drives. IBM has not said "this broke, we fixed it" they simply release new models with higher densities. The consumer will not know if the GXP line has been fixed until 12 months from now when the drives have had some time to... err.. mature.
2) I haven't observed a higher rate of failure with the newer GXP drives either, but they're not old enough to know. However, if you wanted a reliable car, would you buy a 2003 Honda or a Kia? There's probably not much data on the 2003 models yet; all you can do is go with the manufacturer's previous models.
3) More drives, more reported problems. Can't argue with that, but I don't know if the "number of drives sold" data supports it. I'm guessing the lawyers involved in the class action lawsuit have a better idea.
4) I'm not touching this one.
5) Yeah, you're probably right about the 8 hour thing being blown out of proportion. Kind of weird that the other manufacturers don't suggest that limitation (correct if wrong). My guess was that they expected the drives to last about a year running 24x7 so they just dived that number of hours by their warranty (3 years) so they would only have to replace half of them.
6) I, personally, wouldn't blame IBM for any data loss. I do keep backups, and I recognize that HDs do fail. IBM has stood by their warranty promptly replacing the drives that have failed. Their Drive Fitness Software is easy to use and appears to be quite good at finding problems. The RMA process is web-based and painless. That said, I do think 75GXP was a shoddy product and until IBM explains why and what they've fixed, or at least goes a couple of years without such an apparent problem, I would not recommend that others by IBM GXP drives. The performance difference between modern IBM, Maxtor, Seagate, and WD drives is trivial, as is the cost, and there's no reason to take the risk with IBM.
From a broader perspective, I think buying products very similar to ones involved in class action lawsuit is probably a bad idea, especially when an obvious alternative is available.
Oh yeah, sorry for "thread crapping" uwannawhat. No offense is intended.
That's it; feel free to flame
