I am unhappy with beachballing on my upgraded G4 mac mini silent upgrade PPC 1.5ghz, 1gb ram, 100gb/7200 internal hard drive. The ram limitation was something I did not expect when buying it. So, if I buy a firewire ministack or mini enclosure with a 250gb or 500gb hard drive with a 16mb cache, will that improve any performance? I did not know that a firewire Hard drive connection was as fast as an internal hd connection. (Is that true?) If it is true, then I suppose getting a huge hard drive with 16mb cache and 10,000 rpms would probably speed the little mini up... right? Anyone got any suggestions? The poor mini is only four months old, she's the top of the line PPC, but she's a bit slow because of the ram handicap. P.S. DOes it matter if the external drive enclosure is SATA or ATA for the PPC mini?
