What speeds should my hard drivers be able to write to each other at?

I have a new wd aaks 320gb hard drive and an older sata seagate hard drive. Im not sure if its sata I or II as its 3 years old but its sata at least.

The seagate doesn't seem to be able to write any faster then 25mb a second to the other and usualy is sub 15mb.

Is this normal?
 
Measured using what?

Filesystem to filesystem copy using Window's explorer isn't going to show you anything near the theoretical transfer rate limit due to overheads etc.

Run HDTach on both drives to get a better idea of peak sustained performance.

well since he wants drive to drive, hdtach isnt going to do bugger all is it lol

as for explorer well...vista showed a peak of 65mb/sec copying from one 500gb aaks to another on my pc.
 
i just using what vista tells me, i knows its not accurate but i shouild still get similar numbers to everyone else. So im significantly bellow you. MMM could it just be that the drive is 3 years old and im not sure if its sata 1 or 2? or should it still be going faster then this?
 
Vista gives me awful transfer speeds too (15-20mb/s from a pair of 36gb Raptors in RAID0 to a 300gb Maxtor Diamondmax 10).

It's far better with the SP1 release candidate installed tho (~55mb/s).

i see. Ill wait for the offical release when its all tuned and just add it. Dont really want to have to deal with uipdating or uninstallign and reinstallig.

Your writes in this situation should be limited by the read speed of the Seagate which you should be able to check with HDTach.

Are you testing this with big files? 500Mb of small files will take far longer than a single 500Mb file due to the delays in updating the file tables for all the new files.
 
ive copyed all my documents and program files off it at about 125gb so i presume there was some big files in that average it aws running between 17-32mb/s i think but if im copying things over which are probably on average under 100mb its more like 7-15mb
