Seagate 500GB eSATA External HDD

Large File Copy:

For our large file copy tests, we zipped up a Call of Duty 2 install folder, which came to just over 3.4GB compressed. First, we copied the zip file from our OS drive to the test drive to measure write performance, and then deleted the file from the OS drive before copying the data back to that drive to measure the read performance.

Small File Copy:

For our small file copy tests, we used 649 6.2MP photographs from a Canon 10D camera, which came to almost exactly 1GB. First, we copied the folder from our OS drive to the test drive to measure write performance, and then deleted the folder from the OS drive before copying the data back to that drive to measure the read performance.
