The Transcend ESD200 continued its strong showing on HD Tune Pro 5.0. Its average sequential read speed was easily double that of both the Seagate and Imation drive; while its average sequential write speed, though less impressive, was still easily 80% more than the Seagate and Imation drives.
However, where it really shined was on the random access performance workloads, where its random IOPs numbers were easily leaps and bounds ahead of the two portable external hard drives with mechanical hard disks. This is just as we had expected because SSDs generally have much lower seek times.
The Kingston HyperX Max 3.0 could not complete the write operations because of an odd anomaly, but generally, read performance was pretty similar to the Transcend ESD200, save for the slightly better random read access performance. In terms of raw speed, the Kingston's random access read speeds were about 18% faster.
