which "old" drive would be faster?

[piller1999]

Drive 1
Maxtor <something> [this is a regular desktop hard drive]
ATA-66
5400 rpm
13.6 gigs

Drive 2
Fujitsu <something> [this is a laptop hard drive]
ATA-100
4200 rpm
30 gigs

Drive 1 is currently my linux drive on my desktop and I'm thinking of replacing it with Drive 2, but I don't want to "slow" my system down.

I know there are all sorts of variables to calculating drive performance, but is it possible to make a decision on which drive is faster?

ps- yes i know i must be the adapter to make the laptop hard drive work in my desktop.

thanks

Need to know the cache size on each.

Both drives have a 2 meg cache.

The 5400 rpm one most likely be much faster then.

5400 def. But its still slow.
