As ubiquitous as it is today, the flash drive as we know it has been around for about a decade, having been first introduced in late 2000. Trek Technology developed the first flash disk and IBM marketed it under the "DiskOnKey" brand, featuring a whopping 8MB of storage. This was impressive at the time considering the form factor and because floppy disks were still widely used to move small amounts of data.Coincidentally, the first implementation of USB 2.0 was also introduced in 2000. Although the interface has kept evolving and became mainstream in this last decade, it's starting to show its age when performance is a concern. The interface's maximum throughput of 60MB/s is no longer cutting it, especially when you consider the fact that its communication is half-duplex, meaning that data can flow both ways, but not at the same time.Even the fastest USB 2.0 flash drives are unable to match today's conventional hard drives. Considering that we often cite hard drives as the slowest component in a computer, it's about time we moved on. The storage industry has been preparing the shift to USB 3.0 connectivity for quite some time. Dubbed SuperSpeed USB, USB 3.0 offers bi-directional (full-duplex) communication and a tenfold boost in transfer speeds as well as improved capabilities, all while maintaining compatibility with USB 2.0 devices.
