Yes, it is. Despite the disk manufacturers' intentionally misleading spec sheets, most hard disks are not very much faster than 30 MB/s. For example, the new Barracuda V transfers between 23 and 44 MB/s, depending on where on the disk you read from. http://www.storagereview.com/benchimages/ST3120023A_str.png Even if the disk were infinitely fast, the Firewire interface is limited to 50 MB/s. I think this product would be extremely useful, if it is trustable. -- Shields.

And the web page claims it's "military-grade" security. It's like, if you know enough to build such a thing, why don't you know enough to use real encryption? Somebody on Slashdot recommended this for Schneier's doghouse list. Now, 712 Mbit/sec is about 90 MByte/sec, which means if it were doing 3DES, it'd probably be about 30 MByte/sec, which is no longer fast enough to be entertaining.

This looks very similar to the dLock device. http://www.enovatek.com.tw/realtime-hd.htm Perhaps they are using the same ASIC? If so, the product is pure crap. Based on conversations that I had with the booth staff at the last RSA conference, the dLock employs DES and 3DES in ECB mode. Meaning the ciphertext on disk can be broken with the most trivial of cryptanalysis. --Lucky
