It should be noted that the two rebates on these drives continues into Nov. The rebate slip has a couple of different dates on it, so it is best to buy and submit rebate by Nov 02.
Update on Performance....
I finally had the chance to crack open both drives. USB: drive is July 2002 manufacture WD ........ Firewire: The drive is an actual IBM Deskstar 120 GXP (not the Jupiter ...) and I think it had a May or June manufacture.
SiSandra gives the firewire drive (via an Audigy sound card) 21940kb/s (standard ide is 24000) . In reality, it took 38 seconds to transfer a 622MB file (16.36MB/S)
SiSandra gives the USB drive (USB 1.1 on K7S5A) , 967 kb/s, and it took 6.5 minuts to transfer 311MB
On my MSI KT3 Ultra2, I had a lot of trouble with drive, and I had to do some work.......
The drive would be seen in Win98SE, but any access would just hang the system. In reality, the system would get VERY slow... 30 seconds to recognize a mouse click. If I then simply unplugged the drive, the system would be fine BUT I would get the warning from the bundled software that I should not remove drives without running safe remove from their sw. This happened on two systems. So, I cracked the case. I unplugged the ide cable and had a look at the chip:

ISD300A1
I searched on the internet, and discovered the
www.cypress.com website where I found that the ISD300A1 (aka CY4612 ) had a reference board and drivers for Windows 98SE/ME/200/XP High Speed storage devices. This led me to their
Windows Mass Storage Driver v.5.16
I unloaded the drivers that came in the box, rebooted, plugged in the acomdata usb drive , pointed at these drivers and VOILA....
it worked.
SiSandra gives the USB drive (USB 2.0 on KT3 Ultra2) , 17493 kb/s, and it took 60 seconds to transfer/write a 652 mb (10.87MB/sec). That is not too shabby when USB 1.1 was 0.8MB/sec
