Braedley writes "When [Ars] last took an in-depth look at USB flash drives in 2005, the landscape was a bit different. A 2GB drive ran nearly $200, and speeds were quite a bit slower then. At the time, we noted that while the then-current crop of drives was pretty fast, they still were not close to saturating the bandwidth of USB2. To top it off, a good drive was still going to set you back $50 or $70--not exactly a cheap proposition. Since our first roundup, this picture has changed considerably, and it leads to a question: has the flash drive become an undifferentiated commodity, just like any other cheap plastic tsotschke that you might find at an office supply store checkout counter?"
