I can confirm a similar observation. I recently put an ACARD ATA/66 card in my 8500 w/ G4/450. I attached the "wicked fast" Western Digital WD800JB "Special Edition" 80 GB drive to it. According to Storagereview.com, it is capable of moving 49.3 MB/s from the faster outside 10 GB, and 29.2 MB/s from the slower inner 10 GB. In my 8500 it could only move 31 MB/s max, 17 MB/s minimum.

I considered getting an ATTO UW SCSI card, which is supposedly bootable, but I also wanted to consolidate all my SCSI drives and reduce the noise in my office. The ATA drives did that (I have another 80 GB 5400 rpm drive in there also.) Finally, despite leaving so much performance untapped, my WD800JB feels noticably faster than the UltraSCSI drive it replaced, which maxed out at 19 MB/s, 17 MB/s minimum. The improved responsiveness in OS X is palpable, the reduced noise (and heat) is delightful, and the cost was worth it for an otherwise worthless machine. -- _______________________ Phil Lefebvre Chicago, IL -- Unsupported OS X is sponsored by <http://lowendmac.com/> Support Low End Mac <http://lowendmac.com/lists/support.html> Unsupported OS X list info <http://lowendmac.com/lists/unsupported.html> --> AOL users, remove "mailto:"; Send list messages to: <mailto:[EMAIL PROTECTED]> To unsubscribe, email: <mailto:[EMAIL PROTECTED]> For digest mode, email: <mailto:[EMAIL PROTECTED]> Subscription questions: <mailto:[EMAIL PROTECTED]> Archive <http://www.mail-archive.com/unsupportedosx%40mail.maclaunch.com/> Using a Mac?
