I have a Lenovo Y470. The hard disk is 500GB 7200rpm and, while copying files from one directory to another, I am getting 22.6MB/s speed.
- Is this slow or average?
- Can I do something to improve this speed?
Depending on the file types, that's not terrible for platters - especially since you are reading from and copying to the same drive.
Some folks on Overclockers were discussing speeds on modern discs, which were in the 50+ range. But that's probably sequential, and really dependent on the manufacturer (and not across the same drive).
Looks like you're copying media items of varying sizes, which won't likely be sequential reads/writes - so that will be significantly slower.
You're probably in the right range for what/where you're copying - if you are concerned about it being a bad drive, try HD Tune to verify your speeds for various operations. Let us see that to give you a better guess since Windows approximates values (and generally does so poorly).
