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.. Flatten the SATA cables where they are mounted to the backplane internally! The cables are bent in such a way that the stress causes them to give poor signal quality.
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. Then the problems began: - both NASes began reporting I/O errors on drives in different slots on an almost daily basis.
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. I have not measured the transfer rate but it is so much faster than my previous solution (computer running Windows Server with hardware RAID 5) that I am pleased.
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. About ten minutes after each rebuild completed, Disk #2 would drop offline again and require replacement. I think Thecus just lost another customer here.
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. Host mumble, done, want a minecraft server you can do it here, email clients, a plethora of ftp clients and downloaders. If you get one of these make sure you check their third party forums here: [...
After 6 months, repeated IO failures & NO support from Thecus
23 June 2011
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. Goal was to operate as a "live" backup system for my network computers & allow me to upload photos from remote locations over a VPN connection. In November, I received my first of several IO failures on a drive. Unexpected, but I swapped the drive out with a spare.
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. I looked at the firmware, because honestly, why wouldn't you do a firmware upgrade? Sure enough it did not match with what was specified for the HDD's.
Summary: Solid build. Cheap plastic door excepting. And if you have the weekend for it to initialize your RAID it looks like it will fit the bill. Over TEN TIMES slower than my same priced QNAP to set up. WOW! Nice bells and whistles but at the cost of some basics. The software seems to lack some polish to. And the RAID, once it degrades, will not automatically rebuild with a new drive like my QNAP. Better than Synology though.
Summary: In terms of hardware and basic specs, this Thecus NAS is exactly what it is billed as: feature rich and fast. I purchased two, because Iwanted to run a remote rSync through my VPN to backup information to a remote location. Basic installation was easy, and the bays are simple to work with. However, the software is not at all straightforward. And documentation is weak. There is a user forum which is heavily trafficked.
