Just my two bits, rather than having a WD vs Seagate discussion, you'd have to compare individual models and get some data. In particular you might want to distinguish between "enterprise versions" or "consumer versions", the former - supposedly - having a much longer MTBF, but with commensurate cost. The consumer drives are not designed for continuous use, ie in a server, but more for desktop use, ie not on all the time, or so I've read from various sources. Does anyone in the community really have any data to verify these claims?
Best disks ever was on old MFM drive made by IBM that I had, 30 MB, gigantic, and it outlasted several generations of newer drives...
Agree about Amazon.. if it's a recent purchase. If not and you need to use the warranty, then:
RMA = return merchandise auth, you call the company, they authorize a return, send you a mailing label to pack the device back to them.
pita = pain in the anal regions
