Pros: East to setup, Hot Swap, different modes to suit different needs, form factor, quiet

Cons: Haven't found one yet

Overall Review: Bought it for a work project. Loaded it with four 2TB drives. Over the course of development we went from JBOD to RAID 10, and Normal modes. Settled on RAID 10 for speed and redundancy. The drive is fast, easy to load and use. When we changed mode, we changed the DIP switches and then hit reset! So easy!! We lost a HD tray handle and IView sent one to us very fast and out the door it went to a customer demo. We have used several external RAID devices, and this one has none of the other issues. It's fast, doesn't rebuild constantly, quiet and variable fan, USB 3.0 or ESATA. Every one of our test servers can interface to it without issue. If it can survive through the next quarter, we will probably be purchasing a few more.

Pros: Many features that are useful, MP3, jpg, mp4 playback, many card slots on the back

Cons: The card slots are on the bottom of the casing, making it difficult to attach cards, or an average size memory stick. They extend below the level of the frame and make the base uneven. My USB ports were inoperative. Small speaker is pretty bad

Overall Review: Ok, to stick on the corner of the desk to play some music at a very low level and view some pixelated pictures when your eyes are tired of looking at your computer screen. Not really good enough around your own home, or as a wow factor with friends.

Pros: New life to older gear in the office. Surprisingly fast when used as directed. RMA went fast and the devices came up on the first go-around.

Cons: Initially bricked them while updating the firmware. Cabling is not intuitive - READ the directions and diagrams.

Overall Review: After initially bricking the two I bought, I sent them back for RMA and got some good advice. On initial use. Wire just the device, bring up the OS and wait for the driver to load. Reboot. With no drives attached, update the firmware. Shutdown. Attach the original drive. It DOES NOT go into the shell but outside it. READ the diagram and instructions carefully. Start the OS. check to see if it recognizes the drive. Shutdown. Attach the SSD and reboot. You should be able to see it rebuilding. Leaving it up for days lets the data get stale. Either manually update the SSD cache or reboot regularly to keep it fast. I have had it up for a few days now and the programs and some of the data load faster. Defraging the drive keeps your exe files near the front of the HDD and those get mirrored to the SSD. I have noticed that the HDDBoost only seems to update itself when the OS kicks in. Doing multiple changes at once seems to confuse the HDDBoost and it chooses what it will do. Best to just follow the KISS method and reboot the computer between steps.

Stand alone mode for the system worked fine, but it advertises online access. EZVIZ closed the devices built in web server for a cloud based system. Nothing in their documentation discusses anything more than creating an account, type in a code and your'e golden. Too bad the device can NOT be behind a firewall or any sort of Internet security that a reasonable person uses in their home. Especially a home that is going to spend $$ on a camera system. Trying to reach the vendor gets you an automated response, and nothing else. There is no documentation or an FAQ that specifies what ports should be open in the firewall to support the cloud. Sadly, the software can see the system on my network, but because it can't communicate to the cloud, I can't add it. I am sending the system back as soon as I can. Too bad I already have holes in my house where I mounted the cameras and ran the wires. That can't be covered up easily. I would assume that the same can be said for the parent company HikVision. Avoid both.
