I think if your gonna buy a new HDD you really have to go with a 7200. Otherwise it's just sort of pointless. Does anyone have any suggestions on which is a good 7200RPM hdd? I've looked at several but I can't seem to find any from Seagate or Maxtor. Are Hitachi 2.5" drives any good? What drives are popular? Thanks.
I have the Toshiba drive (MK-5024GAY) in a Satellite P25 (2.4ghz P4 HT & 512mb ram) and noticed a marked improvement over the original 4200rpm drive.
Recently I put one of the Hitachi 60gb's (HTS726060M9AT00) in the wifes Compaq Presario 2199US (AMD XP-M 2800+ & 512mb ram), an improvement over the original 4200 rpm drive but not the difference I noticed with my Satellite after upgrading it to the 7200 rpm.
Battery life is about the same.
Heat, no difference.
The Hitachi drive is very quiet.
I just bought a new hard drive for my laptop, but it hasn't arrived yet. My laptop came with a 80gb 4200rpm 2mb cache and I upgraded to a 80gb 5400 16mb cache. The 16mb cache was the main thing I was looking for as to thats where you see the performance increase over only 2mb cache. I dont think I would notice much difference between a 7200rpm 2mb and a 5400 rpm 2mb if I were to upgrade just by the rpm's.
