Summary: I have been limping along with this thing for several years, and it has NEVER performed as I would have liked. Today I got a Kernel Panic, so it looks like I'll be buying a new system which will NOT be Netgear. Customer service is crappy (and just to get it requires hours of hoop-jumping). It often drops off of my network for no reason, and requires constant restarting. Despite VERY light use, it has gone through 3 disks.
Summary: Could never get to work, constantly freezes when initiating transfer! Set up at least 5 different times, and used different cables, drives, etc. All have same result. Even downgraded firmware as suggested on forums.
Summary: Bought two of these via Amazon in September of 2010. Bought four more from other vendors, for a grand total of six units, over the next year. All six units performed flawlessly through December of 2011. All six units were operated in fully loaded RAID-5 condition, each unit holding four Seagate 1 TByte 5300 RPM drives. During the 2011 Xmas and New Year holiday, there was a single disk failure in one of the two original units. This was an "ideal" failure.
Summary: I returned this product for the following reasons: 1) The interface is very slow to respond and fairly glitchy 2) The device does not support drives over 2TB 3) I was unable to delete the default volume setup and create something that even remotely utilized my drives. The 3x3TB setup I had each got formatted to less than 1TB, and it was impossible to reconfigure the volume.
Summary: This is among the last of the SPARC-based readyNASes. Hence it is outdated and slow. But worst of all, the firmware is buggy. Especially if you buy a diskless one that you have to set up yourself, you are asking for trouble. Infrant (now Netgear) claims to support these old dinosaurs with updated firmware (last production one 2010; they are currently working on a version to support OS X Lion's AFP protocol).
Summary: This device, whilst nicely presented and constructed, is yesterday's technology. With an old processor and only 256 MBytes, it simply can't keep up with gigabit potential transfer speeds. When I first set it up (very easy) I changed the 'Jumbo Frames' setting to on (as recommended for media files). Big mistake, I got a throughput of only around 7 MBps. When I switched Jumbo Frames off, it rose to 17 MBps.
Summary: I ordered this NAS around last year and added three 2TB drives to it. It started out working fine except the fan, when the controller decides to spool up, is ridiculously NOISY, like a jet engine. So you can't place it in your office or near your media gear. I've hidden mine in a closet in the next room but I can still hear it. That in itself is bad enough but then, about a month ago, I started having problems writing large files to the NAS.
Summary: Pros: Setup is quite easy and customer support is very friendly. The browser interface is quite nice and allows you to quickly set up shares and users and check the status of the device. Installing a new drive is simple and the NAS will auto-detect it and rebuild the array automatically. Media=sharing is also quite easy. My XBox automatically saw the NAS and all the videos I managed to copy to it. Cons: The device does not work for more than a few hours.
Summary: The first three days I had this NAS, I spent about 20 hrs with tech support with problems ranging from unit freezing (multiple times) to the remote access not working. Tech support even rolled-back the firmware saying that the newest (3.5.6) was buggy. We were able to get remote access working temporarily with the roll-back. The following day it stopped working again.
