Summary: I didn't seem to have any start-up issues that previous reviews experiences. I primarily purchased this NAS to serve as a DLNA media server for my home. Functionally it works great. Initial start-up was fast and easy. Documentation was a little weak (especially for ready DLNA application). I'm running (3) Seagate Barracuda 2 TB Drives ST2000DL003 so far no issues.
Summary: I have used this NETGEAR ReadyNAS Ultra 6 for the past year. I installed 6x 2TB drives in a RAID2 configuration with a total usable space of almost 10TB. For the past 12 months I have only rebooted the NAS two times (when upgrading firmware). I have never had one problem with the box. I use the box as a storage server for software ISOs, a large MP3 collection (200GB), and 4TB of video (.avi, .mp4, .mkv).
Summary: My first NAS and I like it. I considered building one from scratch but I spend enough time doing that with my PC. I chose the ReadyNAS because it can back up my PC as well as remote backup family members (PC & Mac), has support for Squeezebox (used by my two Logitech Squeezebox Touch devices), TiVo support (useless unless DirecTV releases their promised TiVo DVR to replace their lame custom DVR).
Summary: I've got 6 x 3-TB drives set up in my unit, and use RSYNC to back up to a remote unit. Netgear issues periodic firmware updates and the unit works flawlessly. I'm very impressed by the ReadyNAS product line. I also use the scheduled power on/off feature. I have no issues or complaints over the past year of use.
Summary: After reviewing various alternative solutions I found the Netgear ReadyNAS Ultra 6 to offer the best solution. The unit came with three disk populated to which I added a further three 2 TB HD.This gave a total of 12TB which once the unit had finished creating the raid system I was left with 9TB of usable space. For the raid to build a complete populated disk array it took about 18 hours to complete once finished the unit ran very quiet and efficient.
