Memory manufacturer Corsair is offering a quite nice looking 4GB flash drive
. The next step in their Voyager line, this is one of the largest thumb drives available to date, with a 19MByte/sec read and 13MByte/sec write, which is above the industry average, making the drive a more attractive fit for larger amounts of data. From personal experience in carrying several portable storage devices around, write speed on small hard drives and flash drives can be paramount at times. It is retailing at around $250, and comes in a rubber waterproof casing to help protect it. If you are dealing with modern systems, you can even install to and boot from USB devices, making ones large enough such as this even more desirable.
