Testing

Although the Mega-Kart is not touted as a "performance" flash drive, we still want to know how it's going to perform. The drive was put through a gauntlet of benchmark tests, starting with HD Tune.



Transfer rates averaged around 19MB/s, which is not super fast for a flash drive, but is probably typical among mainstream units. Next up is HD Tach.



Again the Mega-Kart averages transfer rates in the upper 18MB/s range. Let's see how the drive compares to some other results in SiSoft Sandra 2007.



Performance figures are right in line with other drive results stored in Sandra, maybe a little lower on the smaller-sized files and a little better on larger files, although Sandra is careful to point out that this is a synthetic benchmark only. Let's try some "real-world" tests.

I tried two different approaches, the first using a single large (700MB) ISO file, followed by a collection of around 500 smaller JPG files (250MB) and recorded the amount of time it took to copy these to the drive (Write) and from the drive (Read) separately. Transfer rates were calculated from these times and the Read and Write speeds were averaged to compare to results from HD Tach and HD Tune.



As you can see, the "real-world" average transfer rates were slightly slower than originally estimated by the benchmark utilities. But what really grabs your attention from this graph is the incredibly poor performance of the drive in write operations. Obviously copying files to the drive is going to take longer than reading them back, and I was not surprised at the results of the large file write test. However I was completely floored by the insane amount of time it took to do the bulk file copy, nearly 13 minutes to write 500+ files totaling just 250MB in size. That's a snail-crawling 0.3MB/s transfer rate. I thought something was wrong so I repeated the test, even trying a different set of files on a second computer, but the results were nearly the same.

On to final conclusions.
