So a little update on my NAS. The 1512+ has worked great for the last year or so, with very little issue. One thing I would recommend to anyone with a Synology NAS is to not have it do automatic updates. I am not one to update my computers to the latest OS and I treat the NAS the same way. This is especially true of the last DSM releases, both 5.0 and 5.1 have had major issues upon first release, but have been pretty stable after 3 or 4 updates. The new software from DSM 5.0 forward also makes it super simple to set up the NAS for almost anything I wanted the NAS to do, including setting up an FTP server.
About three weeks ago, one of the hard drives in the NAS failed. I pretty much knew that would happen as about a month before that I decided to use my spare drive for another purpose so that guaranteed a NAS drive failure. The NAS did exactly what it was supposed to do and informed me via email of the failure. The nice part was that I could still download any file I wanted off of the NAS. So I ordered a new WD red 3tb NAS and installed it. Took about an hour total to repair the volume and everything Was back to normal.
I am also very happy with WD. The RMA of my drive was extremely stress free. Everything is done from their website. Just make sure to register your drives (SN and Date of Purchase). I was even able to buy a cheap 2-day UPS label from them. Took about a week total to get the RMA drive back so I am back in business and have a spare drive in hand.
Overall, very happy with this purchase and well worth the money IMO.
