InnoDisk 4GB USB Card vs Transcend JetFlash 500 16GB

Recently got me a new 16GB USB key, so I thought I'd make use of the disk utility that comes with Ubuntu to do a little "benchmark" to see how the new one compares with the old 4GB USB key I've been using for years and years.

So, here's a photo of the two. On the left is the InnoDisk USB key, on the right is the Transcend drive.

Ubuntu's Disk Utility benchmarking feature will wipe the drive (required for write test) so good thing the JetFlash is brand new. The InnoDisk is what I use for Ubuntu bootable USB keys so wiping it isn't much of a problem.

The InnoDisk appears to perform rather consistently. That's a good thing, of course. Strangely, the Disk Utility detects it as a "Generic USB Disk".

By contrast, the JetFlash gets detected properly. Unfortunately, it seems to not perform very well. The average write speed is appalling. The read speed isn't all that better than the old USB disk either.

I've only ever owned (and benchmarked) these two USB disks, so it could be Transcend is just a budget brand. Still, the InnoDisk has been around a long time so there's expectation that even a budget brand could at least be a little better than a much older device.

Apparently, not.
