Hard Drive Transfer Rates

I have been testing the hard drive data transfer rates on my Vista Intel Q6600 computer by copying (using Explorer) two folders between drives and partitions.

Internal hard drives are 250 GB 7200 rpm SATA 300 with 16 MB memory
First drive with two equal partitions C: and D:
Second drive with two equal partitions E: and F:

External USB2 drive 250 GB SATA 7200 rpm 8 MB memory

The results are as follows - copying the folder from the D: internal drive

Copy a folder containing 16 video files total 2.52 GB from D: drive.

To External drive 1 min 44 secs - transfer rate 24.2 MBps
To C: drive on same hard disk 1 min 25 secs - transfer rate 29.6 MBps
To E: drive (different disk) 0 min 46 secs - transfer rate 54.8 MBps
To seperate folder on same partition 1 min 25 secs - transfer rate 29.6 MBps

Copy a folder containing 701 files total 1.04 GB from D: drive
To External drive 0 min 50 secs - transfer rate 20.8 MBps
To C: drive on same hard disk 0 min 49 secs - transfer rate 21.2 MBps
To E: drive (different disk) 0 min 22 secs - transfer rate 47.3 MBps
To seperate folder on same partition 0 min 47 secs - transfer rate 22.1 MBps

I also tested the transfer rate using a USB2 flash drive plugged into a socket on the motherboard - the transfer rate was a measly 0.74 MBps

My computer is set up with the Vista OS and all programmes on the C: drive and all the data files (Documents, Pictures, Videos etc) on the D: drive - which is on the same hard disk.

My E: drive is used for Acronis backups of the C drive and my F: drive for Second Copy backups of all data.

It is clear from my tests that data transfer is faster when moving files from one hard drive to another - it is twice as fast as moving data between partitions on the same drive.

Does this mean that I would be better to reorganise the computer so that the OS and programmes are on a separate hard disc to the one storing Documents and data files...?


How is your computer set up in this regard - and why ...?
