SIIG Firewire 800 cardbus slow in XP

Archived from groups: comp.sys.laptops (More info?)

Have a problem with my new SIIG Firewire 800 Cardbus card. System here is a
Toshiba P25 laptop dual-boot with XP home (SP2) and W2K. SIIG has just
released driver version 1.20 for this card but the problem persists.

On both XP and W2K, my external 200GB Seagate drive is recognized fine and
seems to work OK. However, I noticed the drive appeared to be working fairly
slow on XP, so I tried both DiskSpeed32 or HDTack to test the throughput.
The read speed of the drive with XP is always under 8 MB/s. On Windows 2000,
(driver version 1.01) the read speed is around 34 MB/s.

I contacted SIIG about this and they said they were working on a new driver,
which I assume is the new 1.20. Hasn't fixed the problem. To try to figure
out if it could be a problem with my system, I downloaded the demo version
of Unibrain's UBCore FW driver. With this driver, the speed results are
around 36-37 MB/s with XP.

If anyone is using the SIIG FW800 cardbus (NN-PC8312) with XP and an
external HD, I would be curious to know what read and/or write speed results
you are getting using SIIG's drivers (which are developed by Orangeware).

Thanks,

Cleiber
