The Ultra 4 Plus is a diskless device, so you can install your own drives and add whatever capacity you need. It features bay space for four drives, and it can accommodate most 3.5-inch SATA drives. A pair of gigabyte Ethernet ports delivers exceptionally fast connections, while three USB ports offer the flexibility to connect other devices with a USB connection, such as printers, external USB storage devices, or digital cameras.

With root access to ssh, the box should be very configurable.

These bad units just need to be returned and exchanged for one that is good...You also need to put HCL approved, known good hard drives in these units.

The performance is really very good - especially when compared to my former Sun/Solaris with hardware SCSI RAID with high performance SCSI drives.

Coming from the world of big iron servers and storage systems I was somewhat skeptical of these types of NAS devices. The RNDP400U is a refreshing surprise in that it does all that Netgear says it is supposed to do and more!

I purchased this unit to replace an aging Sun server equipped with a SCSI Hardware RAID array that I have been using at home for years and that has become terribly inadequate in terms of storage capacity. I needed major more storage and I wanted to make certain that it would be reliable over the long term and easy to upgrade as the need arose.

The OBE (Out of the Box Experience) was excellent. I just slipped the drives (2x Seagate Barracuda Green 2TB SATA 6Gb/s 64MB Cache 3.5-Inch Internal Bare Drive ST2000DL003) into the first two bays and plugged it in. I fired up the discovery tool and presto, the web management page came up and I configured the unit. It did take 8+ hours to format the 2TB mirror which I thought was a pretty long time.

Working my way through the menus I discovered the ability to add various Apps which NetGear calls Addons. The most valuable one was the ssh Addon that allowed me to ssh into the unit which as a Unix admin I was pleased to be able to do.

I setup the various shares and user accounts via the web interface and then scheduled rsync jobs to copy the data from my Sun/Solaris server directly to the ReadyNAS.

I also had a bunch of pictures and video on USB drives and found that they could be connected to the ReadyNAS and the files copied directly (using the ReadyNAS web interface) from the external USB drive to the ReadyNAS shares.

I had a 1 TB drive dedicated to music and video storage. In addition, I was setting up my audiophile home theater system and wanted to replace my iTunes 128k mp3 files with much larger lossless FLAC files. I was running out of space, so I started looking for a server to use as a media server. I was concerned about some of the reviews when I purchased this unit last week. I am pleased to say that but for a couple of glitches that I feel are pretty minor and readily fixable, this is one sweet unit. I am computer literate and relatively network literate, so I know generally my way around a router, and its functions. I have my Ultra Plus set up with 3 Seagate 2 TB drives on the Hardware Compatibility List. I figured that I didn't need the extra space yet, and the 3 TB drives would come down in price significantly by the time I needed to throw another disk in. First, installing the drives was a snap. People, READ (AND FOLLOW) THE INSTRUCTIONS! Follow the setup wizard and you will be streaming and backing up in no time, just like I was. So many problems with products are caused by not following the instructions exactly. After I finished with the setup wizard, I installed the latest firmware. All good. Then I copied all of my music and movies over from my desktop hard drive. All good. Fired up my DNLA compliant box in my home theater and there was the Ultra Plus, and I was able to stream very demanding 1080p movies with AC3 with no problems whatsoever, both wirelessly and using a Belkin Gigabit Powerline adapter. This product really delivers. There are tons of extras, such as emails or texts when there are problems, etc.

The glitches: The Ultra Plus comes with a "ReadyDNLA server" built in.

This is the third Readynas that I own and never had a problem with any of them. I test one feature at a time and thus far they have all passed.
The GUI is always available. The Raidar always detects my Readynas. I loaded Orb and can access my Readynas and watch my home videos or listen to music from anywhere that has internet connectivity. Readynas remote (Remote VPN connection for file transfers)works great. I wrote some scripts that has my Readynas send me a test e-mail everyday or lets me know which files are duplicates. The Ultra4 shuts down automatically when the power goes out to my house (Ultra is attached to a UPS). Everything just works. I have tested all of the various RAID levels, rebuilding of drives, drive failure detection and all have worked fine on all of the models I have. My Ultra4 streams movies and music to my IPOD touch, laptops and desktops(Linux, Mac or Windows). I backup all my computers to the Ultra4 over my network. My Readynas sends text messages to my cellphone when the power flickers in my house or if an issue is detected on one of my hard drives. All of the features work...Just make sure you know for sure that you are putting known good hard drives in the unit. They also should be on the HCL (Hardware compatibility list).

Update (April 30,2012) : My Readynas Ultra4 Plus is still going strong. I continue to add photos, documents, etc... and the thing just continues to work.
I am still truly impressed with my 3 Readynas devices and I will continue to keep my precious data on these devices. I have standby fans, hard drives, etc... and these Readynas devices will just not fail.. I actually want one of my hard drives to fail just so I can see the rebuild process in action again...
