If I'd read those reviews, I'd've probably ended up buying a Synology DS-411j. You see, I bought the Drobo because of its BeyondRAID tech. The Synology has "Synology Hybrid RAID" and the Netgear has "X-RAID2", both of which work like BeyondRAID. And the DS-411j apparently works much better as a media server and has a much nicer user interface than the Drobo. With a better media server on the NAS itself, I wouldn't have to keep a computer running all day to watch shows from the NAS via the Xbox on the TV.
I'm seriously considering buying a new Dell, with an i5 and a bunch of RAM and 64-bit Windows. Dell's got pretty good deals on desktops at the moment: $529, no shipping, for i5-2400 + 4GB RAM + 500GB 7200rpm SATA + DVD-RW, no monitor. However, I'm not one to turn down free computers

I'm thinking at this point it's the power supply that's killing the drive controllers, so maybe all I need is a new PSU. Who knows.
