I love the iSCSI options on some newer products like the QNAP TS-639 or even the new DroboPro 8-drive box (not NAS), but the prices are still hideous.

The TS-509 (5 drives) is US$900, the TS-639 (6 drives) $1000 and the Drobo (8 drives) over $1200. All diskless prices.

I was going to buy a second RAID1 enclosure (Newer's Guardian Maximus) but I really need more than an additional 1.5TB of drive space now that I'm going to be capturing HD streams with my PVR. My current enclosure is already at capacity with my music and movie collection - much of which has even had to be offloaded temporarily to other drives.

What to do, what to do... Since I have a PVR/server on all the time, I don't really need a NAS to run other applications, but it does have to be fast at disk IO. I'm drooling over being able to stick 8 disks into the new Drobo (as long as they're fixed the issues from their previous product iterations).
