my server has a terrabyte, my gaming comp has a half a terrabyte, and my laptop has 160gb (and yes, I run out of space on it).]]>Nov 11th 2008 4:14AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 5:12AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 5:03AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/
The real question is who uses more than the next step down in capacity, i.e. 320GB. If you use say 400GB, this hard disk is what you need.]]>Nov 11th 2008 5:38AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 6:12AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 9:15AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 9:40AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/
Besides, attackers don't look for the strong points, they look for the weak points. What matters is *how* security is implemented, and whether there are ways to circumvent it. For example the encryption in the world wouldn't matter, if it turns out that these drives have an insecure way of storing the key, or prompt the user for it (implying a weak key), or if the drive's firmware can be modified to capture the key at next bootup etc.]]>Nov 11th 2008 4:46AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/If you have enough access to the computer to actually modify the firmware, there's most likely other ways of obtaining the key.

Also, while it is true an attack on 128 bit AES would also work in 256 bit AES, that is only part of the story. An attack could very likely be something like reducing the time complexity by square root. In effect reducing 128 bit AES to 56 bit AES, and 256 bit AES to 128 bit AES.
This is actually pretty much what a quantum computer would do to your AES encryption. 256 bit is post-quantum secure, 128 bit is not. Might very important in the years to come. If my drive was stolen today with extremely sensitive information, I would be a lot happier with 256 than 128 bit AES.]]>Nov 11th 2008 5:45AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 8:22AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 3:00PMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 4:49AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 5:05AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 8:32AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/_]]>Nov 11th 2008 5:11AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 9:57AMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 8:01PMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 3:02PMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/Nov 11th 2008 3:03PMhttp://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/http://www.engadget.com/2008/11/11/fujistu-announces-worlds-first-500gb-laptop-disk-with-256-bit-a/
