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: I purchased a ReadyNAS NV+ V2 about a year ago. It seemed to work fine for a while and then the server stopped working. The drive would not start. Tech services sent me a replacement and I moved my drives to the new hardware. It took about 10 hours for the drives to reconfigure and then it seemed to work fine.
Summary: I must say I was pleased with this product, until one disk failed. Initially I didn't know a disk had failed, the unit just failed to boot. Which is why I bough it right? In case of one disk failing, it should continue operating until I replace the disk, YEAH RIGHT! After searching the manual, no help there, then the online forums, I finally realized what had happened. OK, no problem, this is a hot swappable unit right? NO SUCH BLOODY LUCK.
Summary: YOU WILL BE SORRY IF YOU PURCHASE THIS. I purchased this device at Fry's a few months back because of a rebate offer of $100 which seemed like a great buy. However, this machine is a piece of junk. First I used some old drives that were not on the list of approved drives because I could not afford to buy all new HDDs. For a few days everything seemed fine.
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.
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.
