The cables are bent in such a way that the stress causes them to give poor signal quality

Summary: BUYER BEWARE!!! READ BEFORE YOU PURCHASE!!! So this unit, I believe suffers from a design flaw and not IO errors. What you have to do is open the unit and remove the fan. it presses against the SATA cables Then loosen all of the SATA cabling from the harness or zip tie..
Summary: Love this Nas, no more dvd disks- all packed away in boxes. I would have liked to be able to add a second unit for expanding the array, but wasn't a deal breaker now that larger drives have come out.
Pros: Really Fast, Dual core Cpu gives this unit very high transfer rates and power to do so much more. (ftp,web or mail servers). Easy setup less then 15 mins, and that is with the firmware update. Easy to expand, start with one or two drives then add more later. Very fast rebuilds, compared to other ...
Terrible product and worse support. Buy a Synology if you value your time, money, and sanity.

Summary: I purchased two of these for a medical practice with multiple offices and loaded them up with WD Red drives, which Thecus specifically lists as compatible. Initial setup was easy, inter-office sync worked well, and for about a month I was very happy.
Summary: The nas box on itself it's worth 4 start. Thecus provides all of the essential tool to get the job done. It's the third party modules that steal the show. They community is constantly active with new updates and modules from all over the place.
Summary: Like the other reviewer, my N4200 has failed. Mine lasted about a year, but now repeatedly fails to find Drive #2. In one week, my N4200 chewed through 4 hard disks from 3 different vendors (Hitachi, Seagate, Western Digital). Each time I replaced drive I would rebuild the array.
Summary: I got a very good "deal" on this from Newegg regarding price, but should have spent more for a reliable name like Netgear.
Pros: Blazing Fast!! Easy to use Web Interface Great Features.
Cons: Everything Else: BUGS, BUGS, BUGS... If rebooted NAS is not accessible without extensive reconfiguring, even with same IP in place. Just doesn't work and is extremely frustrating. Email notifications will not work, should not be difficult to set up. Just reset my Netgear NAS and setting up e-mail...
After 6 months, repeated IO failures & NO support from Thecus
15 January 2012
Summary: I bought this unit back in May 2011. Added 4 WD enterprise drives (and purchased 2 as "spares" in case one failed). I was looking forward to the RAID features, as well as the email & web server.
Excellent NAS for backing up multiple types of computers

Summary: Great for backing up Windows (via SMB/CIFS) and Mac (AFP + Time Machine) computers. I have not yet tried NFS for my Linux and BSD systems. I have 4 drives in a RAID 5 configuration. Computers are connected via a wired 1Gb network.
Summary: Ok, so I ordered this NAS becuase the SPECS and reviews said that it was a beast when it came to performance tests. I ordered the appropriate HDD's needed to go with it. They were the SEAGATE STD3000DM001 or something like that. I installed the drives and they never showed up as being installed.
