Slow Copy from Partition to Partition on Same Disk :(

[chanchan]

I have two 250 Seagate SATA drives (7200.10) in RAID 0. The 500 GB array is divided into 60 GB and 440 GB, but when I copy files from one partition to another it's quite slow.

Any ideas?

There isn't much you can do since you are reading and writing on the same disk and it can't do both at once.

That is a systemic problem with your setup. I would suggest using a separate scratch disk, reading all data first (writing to scratch disk) and then reversing that procedure for a write.
If you can convince windows to be more liberal in the size of its read buffer, you could improve performance.
