As I suggested before, I finally got the Hitachi Travelstar 7K2000 200GB ((HTS722020K9SA00)
Data transfer went without a hitch-- I think it took about 3 hours (didn't find any precise log info about the whole operation) with True Image to clone about 78 GB of data (the Hitachi was in an external enclosure and plugged via USB). Of course, when I finally put the Hitachi in my laptop, it just booted normally as if nothing ever happened... Well, almost.
- Speed HAS improved, although not as much as I thought (especially for backups and indexing -- understandably since there many other factors involved here) : loading huge documents, databases, bringing the computer out of hibernation, etc. is faster. Maybe, what... 30% faster ?
- Temperature is about the same (maybe 1C more),
- A bit
more noisy it seems (nothing to complain about though),
- And, mush more space.
I must say I'm happy overall.
