Actually, when it all arrived I discovered that there wasn't enough space in the bay to fit the drive *and* the adaptor (doh!) so I've had to go out and buy an external casing for it. Now, I did some tests using Hard Disk Toolkit, and I came out with some (IMO) interesting results. Here they are: Sustained Sustained Average Average Drive read write access time seek time ------------------- ----------- ----------- ------- ------- IBM 9GB DNES-309170 2674 kb/sec 2761 kb/sec 10.1 ms 6.6 ms Jaz 1GB 3251 kb/sec 1627 kb/sec 19.9 ms 10.3 ms WD Caviar 4GB ATA 8885 kb/sec 5641 kb/sec 15.7 ms N/A Does anyone else find this weird? How can my crappy old Jaz drive achieve a better sustained read rate than my new IBM drive? Actually the IBM drive performs much better overall than the Jaz, I guess due the improved access and seek times, but it doesn't come close to my 4GB internal ATA. Apple states that the beige G3 SCSI bus is capable of handling 5MB/sec (which is adequate for my present needs). So how can I get better results out of my IBM drive without installing a new SCSI card? I guess the other option would be to use the IBM drive as my boot/storage disk, and use the internal ATA drive as my audio work disk, which seems daft. Any ideas on a postcard please. Many thanks Harry.
