Setup and testing

Benchmarking external drives such as this is something of a mixed bag. We ultimately have to ask whether speed is the main consideration when purchasing an external drive enclosure. We certainly want our files to transfer this side of the weekend, but provided transfer rates are at least competent and useable, are not other features more important when making a purchase? Nevertheless, we need to see how well these two products perform.

Testing Hard drives 3.5" - Maxtor Y200P0 200GB
2.5" - 40GB Hitachi Travelstar

Testing software: HD Tach RW 3.0.1.

Test results

We'll start with the 3.5" enclosure. We've included results for a 3.5" Icy Box as well, for comparison. Please note that the Icy Box results are not those from the original Icy Box review we did. The same Maxtor Y200P0 200GB hard drive was used in both enclosures.

3.5in USB results

The Ultra enclosure demonstrates more consistent sustained transfer rates through its USB interface, barring a couple of significant blips when writing towards the end of the disk. There are numerous firmware versions for the Prolific chip out there, and aside from implementation differences and power delivery issues, this is the only factor which might influence the results. Nonetheless, both enclosures read and write at speeds you'd expect, but the Ultra is more reliable in this test.

3.5in Firewire results

Here, we're in danger of having the most exciting benchmark to grace the HEXUS.labs... ever. Both enclosures are equally consistent. Read performance over Firewire is ever so slightly better. Writing isn't as nippy as over USB 2.0.

These benchmarks demonstrate the 3.5" Portable Disk Enclosure as a capable product that will deliver the expected level of performance from such a solution. On now to the 2.5" model.

2.5in USB results

As HD Tach gets towards the outer edge of the disk, performance starts to tail off. Clearly the IDE to USB2.0 bridge isn't doing much to limit performance, able to transfer data quicker than the disk can. Again, performance is good. No records are going to broken here today, but backups and large file transfers won't have you waiting around forever.
