Pros: Performs as advertised. Literally does everything a consumer and small business could imagine a need from a NAS. I got it for the iSCSI and virtualization support. Loads of other apps that work great and can be updated. 4 NICs allow for LACP and multiple VLANs. Everything just worked straight out of the box. The GUI is easy to use and get it up and running. If you have advanced technical knowledge it enables the higher end features and customizations easily. Love this product.

Cons: Can be tricky to find a switch that works with LACP, link aggregation. Follow their compatibility chart. I found a cheap one elsewhere that supposedly supported it. It did, but only after a firmware flash. Not Synology's problem though that is a switch issue. No real cons with the device itself. Love it so far.

Overall Review: Make sure you get a battery backup on their supported list and configure the autoshutdown on powerloss. If you leave write caching on (which you should for performance) you can lose data if the power goes out, which could potentially lose all your data. No biggie if you have the UPS on and it shut the system down when the battery get's low. Also good idea to get NAS aware hard drives like Western Digital Reds. I used 5 - 4 TB drives for usable space of about 14 TB when RAID 5. I use this for my file server, and also for iSCSI storage for my Hyper-V cluster. Love the MPIO it supports. Great for my home lab and testing stuff. This thing just works and easily at that.

Pros: When it works the keyboard is awesome, very solid, and great functionality. I love the cherry MX keys.

Cons: Product came basically DOA. I'd have to wiggle the mini-usb connector to even get a flash of light on the keyboard. Not wanting to have to RMA the keyboard I tried re-soldering the connector (as others have noted it is cheaply done and breaks very easily). The pins were too fine for my poor skills so I spliced another USB cable on the pigtail directly. I suppose I should have just RMA'd the keyboard, but I figured I'd just get another defective one that would break soon if it didn't come already broken. Plus I didn't want to wait another week or 2 for it to come.

Overall Review: I would avoid this keyboard at all costs until it is redesigned. Really there is no need for a detachable mini-usb cable to start with. Why not just directly connect it to the keyboard? There is no PS2 to swap it out. I had read the reviews and new there could be problems, but it mostly had high stars. I wouldn't go with those reviews, it is an awesome keyboard when working. But you shouldn't have to resolder right out of the box. Come on where is your QA? How can you ship a dead keyboard? It can't be that hard to plug in and test it before shipping.
