Kingston Technology today announced its new high-capacity USB flash drive, the DataTraveller 300 (model: DT300/256GB), which packs a massive 256 GB of data in a pocketable package measuring 70.68 x 16.90 x 22.99 mm (as big as a typical flash drive, nearly twice as thick). The package design is cap-less, with the USB connector popping-out at the push of a slider. The drive offers read speeds of 20 MB/s, and writes data at 10 MB/s. The company packs its own data-encryption software to protect data. The drive supports Windows ReadyBoost technology on Windows Vista and Windows 7 operating systems. Backed by a 5-year company warranty, Kingston is selling the DT300/256GB for 775 Euro.
