I found a very interesting article here. If, for some reason, it doesn't work for you, go here and click on "Twin-head hard disk...." under "Today in Technology".

Scarabs claims that it has developed a hard disk drive (HDD) with two heads that prevents disk files published on the Web from being altered by hackers.

Scarabs put two heads on a HDD, a read-only head that is connected via one cable to a Web server for people to browse content on the disk file and a read/write head that is connected by another cable to a PC for administrators who renew the data.
I think the idea is very good. They seem to be marketing it for web servers, but I think it would also be very advantages for other servers, including file servers, so that "disgruntled employees", etc. can't start deleting files or rearranging things on the file server.

What do you think? Do you see a future for this technology? Would you spend the extra money for the added security? Do you really think it'll be as secure as they claim? I want to hear your opinions... I've read a few articles about this lately, and I find it very interesting and want to hear other's opinions on it.
