It's a 160 GB / 7200rpm -
http://westerndigital.com/en/products/wd1600b008.asp

Setup went perfect however I can't seem to get the speed where it should

be.
I am formatted as NTFS, the USB 2.0 is a PCI Adaptec DuoConnect with 3 USB
2.0 and 2 Firewire ports (I have nothing in the other ports yet).

I run a benchmark program on my internal Western Digital and get 33 MB/sec
read write. Excellent.

Run benchmark's on the external USB 2.0 drive and get Read 10MB/sec and
Write 8315KB/sec

Is this it? Should I not get like 33 MB/sec? I need to edit video and
thought the USB 2.0 would at least be as fast as my internal.

I installed all the latest XP Pro service packs, system is completely up

to
date on HD drivers. Also installed the latest Adaptec USB 2.0 card drivers
(Enchanced Host Controler).

I just bought the drive and can return it, but Western Digital tech

support
can't figure it out. All they suggest is download the latest drivers and
that is what I have done.

Any other options? Does it sound like there is a problem or is this all a
USB 2.0 external drive can give? The system is a P4, couple years old and
PCI slots should be fine I would think. Unless there is different speed

PCI
slots.

Any help would be great...thanks!!

Yeah, that's seems about half of what would be reasonable. I have almost the
same setup as you. 'Cept, I'm running a WD 80JB with 8MB cache through a USB
2.0. I'm getting 24MB/s throughput using Diskspeed 32, whereas my internal
RAID 0 is getting 56MB/s. I also have an internal Seagate(old) IDE ATA 33
for my other OS(dual boot) that gets what your WD 160 is running at(9MB/s).
But Rod is correct, FW will run faster even though USB 2.0 supposedly has a
faster burst speed(400Mbs/s vs. 480Mbs/s). So, I recently ordered a FW
external enclosure and will probably put another DVD writer in this USB
enclosure.
If you're using Sandra as a BM program, you'll get lower values. Try
DiskSpeed 32, ATTO, and the one Rod suggested. Do you have the Intel
Application Accelerator loaded(UDMA)? What's your CPU speed? Also, keep in
mind that whatever your drive is rated at(ATA 66, 100, 133, etc.), it'll
usually run at less than half of that on the average in everyday use with
normal setups.
