Believe us, we know just how foggy things get when trying to remember back to the 13th day of December 2007, but sure enough, it was on that fateful Thursday that we received our first sneak peek at QNAP's (then) forthcoming TS-409. Today, however, we're looking at the official product: a 4-bay, hot-swappable NAS that supports such beautiful features as online RAID capacity expansion and RAID level migration. Reportedly filled with "disaster-proof enhancements," this unit also includes an HDD S.M.A.R.T. function that provides complete hard drive information including temperature and overall "health." No concrete word on price, but a quick scan of the intarweb pegs it right around $600.
