The NAS, whilst it is feature rich, I've disabled everything other then full-disk encryption. The only thing running on it is Squeezebox: http://oinkzwurgl.org/ssods_intro
Interesting, thanks. I originally got a 4 drive QNAP but it's way too limited in terms of CPU, it couldn't keep up with rsync+ssh transfers. I ended up replacing it with a HP microserver and am very happy with it. So far 4 drives in RAID6 have been enough but it would be nice to have versions with more drives. I guess I could fit a 5th drive in the optical drive slot.
Edit: I see that these Pro QNAP versions are actually high-specced and high-priced Intel machines. The HP microservers still hit a sweet spot of low price and ECC ram though. QNAP must be making a bundle by effectively differentiating themselves in their software. Nothing in the hardware seems to justify the pricing.
I'm on a N40L and found that FDE taxed the CPU too much underneath a RAID 6 array to be useful. I've heard that the more recent models are CPU upgradable to CPUs with AES-NI. What sort of FDE R/W speeds are you seeing?
