I'm about to purchase two harddrives for both mine and my girlfriend's iMac G3 snow and graphite. I'm unsure of the speed of the HD's at the minute, but i'm considering upgrading to IDE/ATA 80GB 7200rpm from either Seagate or Maxtor. If anyone has any help, ''do's or don'ts'', drive recommendations or any stories of their own upgrades please let me know. Will i notice a difference ? What about the 8mb or 2mb cache options ? My girlfriend uses her G3 for photoshop and illustrator work. Any help is much appreciated. Rich.
