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 67MB/s read speeds through firewire. And on the full PCMark05 tests of real world performance, the disk drive has 90.9% 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.
Prior to shipping we fully format the disk for Apple Mac (HFS+ format) guaranteeing that you can plug in the disk and use it within seconds. If you want the disk partitioned in other formats, such as for Windows XP or Vista, then let us know, and we will do it free of charge prior to shipment.
Note: PC Laptops have un-powered 4-pin firewire 400 ports. So to use this disk with a laptop you would need to use the 5V Power Adaptor included and purchase a Firewire 800 to 400 (9-pin to 4-pin) cable. See recommended products below (bottom of page).
Note: The Firewire 800 port is backwards compatible with Firewire 400. We can supply a Firewire 800 to 400 cable (9-pin to 6-pin) which enables the disk to be used with any PC or Mac 6-pin Firewire 400 port. See recommended products below (bottom of page).

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 7200rpm disk is 90.9% of the Pleiades firewire 800 big desktop external disk drive, and faster than the Pleiades firewire 400 version.
