A 25% faster drive won't necessarily get you 25% faster load/store
times. PhotoShop seems to be inordinately slow in dealing with
compressed TIFFs -- I got curious so I set up a cache large enough to
hold the whole file (53MB). The first time I loaded it into PhotoShop
it took 61 seconds (reading from the disk). I then closed the file and
reloaded it into PhotoShop (this time from the cache -- the disk light
never even blinked) and it took 55 seconds. And I'm reasonably sure
that a RAM cache is *much* faster than a 7200 rpm drive!
BTW, Ed's VueScan takes less than 30 seconds to read the same file.

On the other hand I'm reasonably sure the main
bottleneck in my PC when dealing with large scans is the 5400RPM IDE
drive.
A 7200RPM drive would speed up loading and saving files by at least
25%.
Two 7200rpm drives in a RAID array should be significantly better
still.
Loading and saving files is the no.1 timewaster for me when working
with
film scans on my PC.
