Pros: I have had this NAS running 24/7, and have used it daily since my first review on 3/17/2013. A large portion is now dedicated primarily for serving media throughout my home network. The rest is for data backups.
Summary: There are firmware problems they are trying to fix. My unit would not go to sleep and ran 24/7. The backup software couldn't see my OCZ Vertex 3 (my C drive). The firmware version wouldn't show up in the places it should.
Pros: cheap, easy setup, lots of storage
Cons: Seagate has put this product on production hold.
Summary: If I ever get this to work, I'll update my review to reflect how the product actually works. Immediately I encountered an issue. This comes without drives, so you have to buy one or two drives that are compatible with it. In the printed instructions they provide a link to the list of compatible drives for the system. That link is dead, so I had to do some searching to find the list.
Summary: This unit only supports 5 kinds of drives and these drives are only made by Seagate ( http://ow.ly/jtSwD )! Find my review for the diskless version of this NAS where I attempted to use Hitachi drives and Seagate drives (which were not on the supported list) only yo find that the NAS would drop from the network and refuse to accept the disks. Therefore you must be careful when/if you decided to update the drives on this NAS because it may become a headache very quickly.
Pros: The USM feature is a fantastic way to do backups by hand. If I were still working in IT I would use this feature every day but as it is my file transfers of scientific data are only done via LAN for time and security reasons.
Cons: I am a linux user and require SSH access which this unit does not have.
Summary: Not stable if you do not set it up correctly. Based on other reviews you could get the older firmware and have trouble upgrading it. This could be quicker as raid1 maxes at 40Mb/s. I would prefer it to push 55 Mb/s .
Pros: Good price for a 4Tb Nas.
Cons: Has dvd for software. Con if you can't use a dvd reader with your gear.
Summary: The password reset feature is nice and simple, as you can reset to the default admin password without having to reset the entire device and losing any data. However, I consider this a Con because if the unit was easily accessible and someone wanted to have access to the data, they would simply read the manual, get the default password, and reset the device. I think that there should be a little more protection in the password reset feature.
Pros: Packs a punch for a small package! Easy set up and use for the average user to the power user. This is a very versatile unit with a wide range of capabilities that will appeal to just about anyone looking for a personal storage cloud or small business back-up needs. Very simple to set up-once connected and turned on, the set up process took less than 5 minutes, in another 10 minutes, I was streaming movies and transferring files.
Cons: The unit arrived with firmware version 2013-60152. A new version of firmware, 2013-60193, has been released and appears to have corrected the few minor bugs I found with the system. The user interface was sluggish through the browser with the old firmware version; the revision in the new firmware version did not appear to increase the speed of navigating the system through the browser.
