Buffalo's TeraStation Pro NAS bumped to 4TB

Check it rippers and thieves, Buffalo is now offering their TeraStation Pro NAS in capacities up to 4TB. That's right, 4,398,046,511,104 bytes which you can carve up to your RAID 1/5/10 delight. It'll cost you ¥378,000 ($3,142) for the ready-made pleasure; pretty steep for those of you with the DIY chops to fashion your own NAS from a quartet of $399 Hitachi 1TB disks.
