I'm imminently buying a new high-capacity (500 or 750GB) drive for my desktop system. The disruption caused by loss of a drive with that much data is such that I've decided to spend the extra and get an enterprise drive (WD RE2 or Seagate ES ranges). I would imagine this is a pretty common idea nowadays. I have some questions on the decision.
System - desktop system running 24x7, P4, 1 gb ram, XP Pro, non-RAID
Usage - heavily multi-tasking (heavy parallel use of each of IM clients, web browsing, p2p, office applications, movies and occasionally movie encoding).
1. Comparing (say) the current WD 500GB RE2 and the Seagate 750GB ES models, are there any significant differences in either reliability or speed?
2. Is there a consensus whether the TLER (and related seagate feature) on these drives can be disabled, and whether this is useful or important in the above environment?
Anything else important about making a choice?
