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 a D-Link DNS-323 2-Bay Network Attached Storage Enclosure which has been great but wanted a NAS with more capacity and purchased the ReadyNAS Ultra 6 Plus. From the start I've had a terrible experience it. It refuses to operate with anything more than 2 hard-drives in the system. Netgear tech support are polite but I have been in regular email exchange with them for a month and the problem is no closer to resolution. I would avoid this lemon.
Original product was defective, have received 3 replacements that have also been defective.

Summary: I purchased ReadyNAS Ultra 6 Plus from Netgear via Amazon.com which was received on June 15th, 2012. I began to immediately experience problems with the device. In the first week of running the NAS device 4 of the 6 installed drives became non-operational. This unit is not sold with drives; however the manufacturer provides a list of compatible drives on their website. The 6 drives installed were all Seagate model ST2000DL003 from that list.
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 sent in a review for this about a week ago and it never showed up. Just like the NAS bought through Beach Audio, DOA. The unit exhibited problems from the very start. On boot, it had an error message, "ERR: Could not mount Root RAID d" The management and configuration program, "RAIDar" stated it had a "Corupt Boot" I used 6 SeaGate 2T HD's on the hardware compatibility list found on NetGear's web site.
Summary: I bought the ReadyNAS Ultra to replace an older DroboPro that was just driving me crazy with its ISCSI limitations and systemic problems. PROS: I like the 6 bay technology, the ease of setup and the fast interfaces, both LAN, USA and ISCSI. Ready NAS is very fast, reliable and attractive. As a matter of fact, it sits right next to my AV receiver adorning my other components and looks very professional and neat.
