Thermaltake Vi-On HDD Enclosure
Testing (continued):
HDTune Pro:
HDTune shows a detailed graph of the read and write speeds over time, this will let you see if the drive is maintaining a stable transfer rate or jumps around a lot. Along with the read and write speeds, HD Tune also reports back the time it takes to randomly access the drive. Below you will notice two separate test results, one is for the reading while the other is for writing.

For the reading portion of HD Tunes benchmark it reports back the minimum, maximum, and average read speeds. This will help give us an overall overview of how the drive reads from the disk, whether it be at a constant rate or not. As you can see the results for the internal configuration and using the eSata interface result in having identical results with slight improvements in the eSata configuration. Looking at the graph on these you will notice that it starts out at a high read speed and decreases over time, this happens a lot with hard drives, as they don't read at a constant rate. The USB configuration constantly reads between 29-33 MB/s, this is due to the slower transfer rates of the USB interface.

The results for writing were very similar to the results for reading. The internal and eSata configurations received identical results at an average 47.1 MB/s, whereas the USB wrote at an average of 30.5 MB/s.
DataMarck:
Datamarck tests the drives average read speed as well as the time it takes to do a random seek. Unlike HD Tune above, datamarck does not test write speeds just the average read speeds and the time for a random seek.

Shown above are the results received from the Datamarck benchmark. You will see that the average read speeds of the eSata and internal configurations are nearly identical at 44.4MB/s, which is lower than all of the other reported average speeds. The time it took for a random seek for the eSata and Internal configurations was slightly over 13ms. Whereas using the USB interface the speeds dropped to 30MB/s and the random seek took 30.6ms.
