The A-DATA PD16 is a very solid drive. The use of high quality plastic and aluminum make it very durable. The drive is one of the few out there available with a capacity up to 16 GB. It may not be the fastest but certainly fast enough for larger files as well. The great access time and large size make it the perfect choice for Windows Vista ReadyBoost. A-DATA has also priced the PD16 very competitive, being just a few dollars more expensive than no name sticks. Anyone wanting a very solid, high quality USB stick with an appropriate price tag will find everything in the A-DATA PD16.
