New ProductsThe revolution is happening... you can now get performance and portability! Using the latest laptop-sized 2.5" disk drives you can now get performance close to that of full size external desktop disk drives, yet in a pocketable size that is powered by firewire or USB2.
Perfect for Apple Mac Professional users or PC users, this product is ideally suited to professional video and audio editors and photographers, who need the performance and compatibility of the Oxford 934 chipset... the best on the market.
Look at the performance graphs below... over 68MB/s read speeds through firewire. And on the full PCMark05 tests of real world performance, the disk drive has 84.4% of the performance of the full sized Pleiades Firewire 800 external disk drive with Oxford 924 chipset which has a desktop 500GB disk drive inside.
The enclosure is made of solid aluminium with unique 3-way cooling (see details below) enabling heat to be dissipated from the disk so you can use it for extended periods without any danger of overheating. The disk is practically silent both when idle and when in operation.
The product has a 2 year warranty.

We have measured the performance of this KC21 drive, using the firewire 800 interface. This performance measures REAL LIFE disk performance with simulations of starting the Operating System, loading applications, and general writing and reading data. So the relative performance gives an indication of the difference you should expect between various products.

Performance shown as relative percentage of highest marks:
These figures show that this KC21 with Seagate 500GB 5400rpm disk is 84.4% of the Pleiades firewire 800 big desktop external disk drive, and almost the same as the Pleiades firewire 400 version.
