Summary: The A-DATA S805 is by no means a speed demon. Sure, it manages very good - albeit a bit weird - read performance, but lacks the write speed of modern flash drives. Those who go for the S805 are clearly shopping for a stick which is durable and can easily be carried around on your key chain or hooked to your backpack. This unique aspect is more important than any performance. That said, this S805 is certainly recommendable in its own way.
Pros: Unique and practical shape, Very durable, Supports Vista ReadyBoost, Metal casing, Can be used as a key chain, Good read performance, Lifetime warranty, Available in two colors
Cons: Write performance is quite slow, Fairly expensive, No activity indicator LED
