Seagate Barracuda Green ST2000DL003 2TB 5900 RPM 64MB Cache SATA 6.0Gb/s 3.5"
I bought 4 of these and they work great in a raid 5 so I thought i should add them to the list. I have noticed a slow down after 24-72 hrs but I found a post that might explain the issue (upnp server basically slows it down to a crawl...) so other than the occasional reboot (and total lack of osx support at the moment...) it's been fine.
