I bought this white Transcend JetFlash 370 16 GB Pen Drive. It was a bit pricey when I bought it. But I must say that this is a jewel of a storage device. Though it is a USB 2.0 one I am quite satisfied with the uniform transfer speed that it gives.
The reading speed is about 15mb/s to 20mb/s while the writing speed is between 6mb/s to 10mb/s.
The default space that it comes loaded with is 14.9 GB. So don’t be upset by not seeing the 16 GB mark. All other pen drives will give you the same space.
