On my G5, why would opening and saving a file take less time on a FW800 drive (Lacie D2 Extreme) than on an internal SATA drive?
I got the following times:
SATA HD:
Open: 27.1 seconds
Save: 51.6 seconds
FW800 HD:
Open: 18.7 seconds
Save: 27.2 seconds
To get those times I opened photoshop, then opened the file from the SATA drive. Modified the file and saved it. I then closed Photoshop and did the same thing with an identical file on the FW800 drive.
The FW800 drive is almost twice as fast as the internal SATA drive!
In my G5 I have two internal disks. The first is the 150GB drive that came with it. The second drive is a 35G Western Digital Raptor that is only used as a scratch disk for photoshop. The G5 has 2.5GB of ram. In PS I have the max mem useage set to 75%.
