10 MB/sec transfer on IDE133 Hard Drives

I have two hardrives on one channel.

Windows XP Performance monitor shows a transfer between drive 0 to drive 1 goign at only 10M/sec (with a max of about 30).

How can I speed this up?

What kind and speed of drive?  If you don't know, exact make/model# helps us detremine the speed.

What kind of motherboard / ata controller?

depending on your equipment, 30mbps isn't that out of line for your drive.  Use HDTACH to get more accurate reporting though.

Most of today's ATA133 drives on newer motherboards run anywhere between 10 and 50mbps, depending on the drive and the mobo and the file being read/written.

Remember that you will NEVER get 133Mbps out of your ata133 drive, if that's what you were thinking.

I know I'll never get 133.  But I was thinking maybe half of that would be nice!

The hard drives are IBM Deskstars, 7200RPM.  One has 2MB of cache (80GB), the other 8MB (130GB).  I'm using a GigaByte KT333R motherboard.  Raid is not configured.

if you download hdtach or winbench you can get some good measurements.

tested with a 60GB deskstar hdtach shows this:
Access time (ms) 13.8 ms
Read speed max (kps) 41618 kps
Read speed min (kps) 15447 kps
Read speed avg (kps) 30781.7 kps
CPU utilization 9.7

winbench shows this:
Disk Transfer Rate  
- Beginning: 36500 KB/s
- End: 21300 KB/s
Disk Access Time: 11.5 ms
CPU Utilization: 5.50%

these should give you a good idea of what yours should be capable of.  But like I said, these programs will give you a much better measurement and point of comparison than XP will . . .

Would my hard drive 1 to hard drive 2 transfers be faster if they were on separate channels?

Your best performance is always to have each hard drive on a separate channel, if you can.  It's also best to have each ATAPI device (cdroms / rw's) on a separate device if you can.

So, if you have two drives, I'd put them as primary master and secondary master.
If you have one atapi device, put it on as primary slave.
If you have two atapi devices, put the main device on as primary slave, and the secondary device (in terms of usage) as secondary slave.

That pretty much always gives you your best performance.
