A: This was one of our first concerns and to mitigate this risk, we use AES-128 to encrypt everything that we write to the device.

However, this slew of benchmarks [tomshardware.com] shows Vista to be slower across the board then XP.

I've been using Vista for quite a while now for primarily programming and gaming. "faster" has two areas for me:
I think Microsoft may have unknowingly shot themselves in the foot by making some of the betas public. This made a lot of the "almost-enthusiast, but not really knowledgable" people decide that because the beta had some performance quirks, the RTM must too. And they've been surprisingly loud with it.
Other than some old hardware not having drivers yet, every person I've talked to who has actually ran Vista for a week agreed it is an improvement.

I imagine that if I ran solid benchmarks for a single type of task that it would come out less than for XP, but when I multitask my perception is definately that Vista runs smoother.

For example, where are they storing the encryption key? It's certainly on the PC somewhere accessible to all for now.
Security programming is hard, really hard. I don't doubt that Microsoft has very gifted security programmers, but I very much doubt that they were given free reign. Most likely they were forced to implement managerial compromises that, well, compromise the system security.
Also consider the CPU cycles required to do the encrypting/decrypting and that this is just one of MANY tasks the OS is doing with encryption-bound services. Those are just two factors that hardly constitutes speedy/secure anything.

Doesn't seem like Linux can do that. I'm not making any judgement on the relative benefits of Windows and Linux here, but the kneejerk fanboy "linux can do that too!" response needed to be addressed.
