hIOmon SSD Performance Monitor - Understanding desktop usage patterns.

One_Hertz thread on the FusionIO got me thinking about file transfer speeds.

Here I experiment copying a 712,394KB file from the C drive to the E drive (Both X25-M160GB drives).

In the first image I use Window’s Explorer to copy the files from the C drive to the E drive and then I use TeraCopy.

In the second image I copy the same file from the E drive to the E drive, first using TeraCopy and then with Explorer.

I’m not 100% sure how to interpret the results, but it seems a file copy operation using Window’s is done with cache. I’ve seen, or more accurately heard; that the transfer speed Windows reports/displays is cache speed, as a hard drive can be heard clanking away long after Windows reports the file transfer as being complete.
