HDTach is a free hard disk benchmarking program from SimpliSoftware. It is used to measure the Burst Speed, Average Read Speed, and Random Access Time of the hard drive. In this case, it has been used on the same hard drive both internally and in the external enclosure.
As you can see, the inclusion of the eSATA interface for the external enclosure was surely a good idea, and it offered almost equivalent average read speed as if it were internal. The burst speed did not reach the same level as the drive reached internally, but that's respectable from an external drive. Let's move on to our next test.
Sisoft Sandra is a synthetic benchmark utility capable of reporting and benchmarking a wide range of system components. For our Seagate SATA II hard drive we ran the read speed utility both internally and in the external enclosure, three times each to ensure accurate results.
Once again we see the external eSATA connection being just a bit slower than an internal hook-up, and the access time shows the same. We can conclude that all though the external enclosure with use of eSATA is not quite on par with the internal drive, there is a negligible difference in most cases.
