Following on from me moaning about pointless USB sticks that vendors now give away as freebies, I decided to test out the performance of those devices to see which were worth retaining. My wholly unscientific test measures the average throughput on writing a file as large as possible to the device. For 1GB and above, I used a 942MB file, for smaller sticks, I used a smaller file that would just fill the device. Performance is measured as throughput over time, in MB/s. To ensure fair play, each USB stick is formatted using Disk Utility on the Mac before writing. The results are quite interesting and are shown in the table below.
|Vendor||Capacity (MB)||Performance (MB/s)|
Xsigo fared the best with an amazing 8.6MB/s, followed by Brocade, and 3Par languished in last place with a disappointing 1.9MB/s. There’s also a clear “middle ground” of devices around the 4.5 – 5.0 MB/s range. Of course this test is totally unscientific but it’s nice to think how much vendors are spending on us when they decide on the quality of their freebies…..
