Speed limits?

Crystal DiskMark’s 1GB file-size tests certainly seem to suggest as much. The interface adapter is a huge bottleneck. Never mind reaching the C300’s true potential, neither the 64GB or the 128GB drives tested even approached anything close to Iomega’s projected figures.

Now, for a buyer beware moment. Currently, the 64GB version has a known issue that cripples the write performance in these drives, amounting to about a throughput drop of around 30MB/s with large data chunks. Consequently, Iomega ended up sending me a 128GB drive unit for review which doesn't exhibit this drastic drop in speed.

Even so, the 128GB version fails to achieve its throughput claims and delivers a performance very much the same as Kingston’s HyperX max (also 128GB). It is quite possible that both of these products use the same controller for the interface adapter, hence the similar throttling apparent in the real-world speeds these drives manage.
