I have a Rev C pwoerbook with a 60gig HDD in it and I was wondering if it had an 8mb cache, and also what RPM the drive is.

I suspect its a 4200rpm drive, but would like to know the cache size. I ask because I can get the new Seagate 5400rpm 40gig drive with 8mb cache for my notebook for free, and wondering if since I play a fair number of games whether or not it would speed things up. I know it'll help battery life a little. Thanks in advance for any help.

PS. My PB has the "TOSHIBA MK6025GAS" harddrive.

http://www.generalcomputer.com/catalogs/download/PRICELIST.pdf indicates it has a 8MB cache. I know it is 4200 RPM... I have the same HD in my PB.

The extra RPM would drain the extra battery life if anything. Though reports are it's not much. like 10min or so. But exchanging hdds, does that void your warranty? I know it does on all the consumer machines but I don't know about the pro books.

This same list says that the TOSHIBA MK6025GAS is a 5400 rpm drive, which it is not supposed to be (I have it in my PB). So this price list might not be all that reliable. Does anyone have a link to other info anywhere?

It seems odd to me that Toshiba does not list this hard drive on their site. But, based on what *is* on their site suggests that the 6025GAS has an 8 MB buffer (the 4025GAS and 8025GAS both have 8 MB buffers). The GAS seems to mean 4200. GAX would mean 5400.

Yes, it voids the warranty on all Al PBs. (Titaniums were the last you could change hard drives)

Ah yes that what I was confused about.

I believe it's because the hdd is more accessible. Something like 2 screws and it's out on a Ti. Haven't read about the AL's yet.

Actually it helps battery life due to less duty cycles and more idle time. :)
