Pros: Let me start off by saying that I've had this drive for 5 days shy of 3 years (purchased 11/24/10). I've had a few other drives, but this is still the best. I came back to the product page because it had gone missing and I was considering buying another one. I don't use it much for mass storage these days as I have two 32gb flash drives.
Cons: None! They make 32gb, 64gb, and 128gb versions of this flash drive?! Umm...I'll be right back...let me just buy them all.
Pros: Excellent speed for the price, considering it's a USB 2.0 device (which has a maximum effective throughput of 35 MB/s). Cheap, well-constructed. You can't ask for much in an inexpensive flash device, and this one performs admirably for the price.
Cons: I don't see any cons. Sure, it's not hitting 35 MB/s. But does anyone really expect this out of a USB flash drive at this pricepoint?
