Question: Can I run this nas with partial hdd ie using 3 bays while keep other bay's empty
Document: The dual fans can be easily replaced by design but is an increased cost factor to the original cost of the Synology device. If Synology used very quiet fans in the first place, it would eliminate the cost and also make the client more satisfied by reduction in fan noise. I am only using 3 of the 5 bays for now. I realize spinning hard disks can also generate noise, but I am using relative quiet, power-saving 4TB Seagate drives (x3). (2)  I can live without an HDMI port, but it would be surely nice to have that incorporated into the design of the device.
Have had this approx 6 months now - is much faster than a windows 2008 server on the same network - has worked flawlessly - Highly recommend this unit. Used 4 WD Red drives 3tb each to render 8.3 tB formatted in their default RAID (proprietary to Synology)  one slot still empty.
Ordered & received DS 1513+ ontime. No damage at all. Plugged in 5 'red' Wd drives (2tb ea. ), followed directions and had a working NAS box in about 5 min. Very easy to put drives in drive bay cages. Best instructions for a NAS box i've ever seen. I've installed 7 nas boxes for customers in the last yr. and was amazed how simple this  was to set up. SPEED! SPEED! this thing is as fast or faster than my computer which is fast. I've had users call me & ask me how i got this box to run this quick.
But that's super irritating if you have a WAN with several computers synchronizing files and one's in Hong Kong, another in New York, etc. You have to push 2, 4 or more terabytes over the WAN every time there's an error or problem because you have to start from scratch with a new empty folder on the destination computer. The only reasonable solution is to ship the computer to the location of the NAS to transfer the data using the cloud sync.When I asked support who could have thought of this madness, they said, "The system is sensible and no one else complains about it.
This is currently a 1 or 2 star device for me so far. Easy to setup, somewhat. Liked their method of installing HDs when I could afford them e.g. beginning with 3, then adding a 4th and/or 5th. Using Synology's &#34;RAID&#34; method expansion would appear to be painless. I installed 5 WD &#34;Red&#34; drives all at once. Only took a few minutes to get started.There is not a *simple* overview page, e.g.
Apple clearly is pushing this model with their new devices that run on Flash RAM and support external drive arrays. I would seriously have considered their Promise offering were it not, as I've said earlier, the software that comes with this device. My new iMac (to be delivered next week) will have the 1TB Flash HDD and all storage will be on the Synology unit.I'm also using Amazon's AWS Glacier service to backup the device. (I tried Symform at work on that unit, but wasn't real happy with it, but that could have been for a number of reasons, some mine, some theirs.)
I have been running the older model for about two years at home and needed to expand for our small business needs. i equipped this 1513+ model with five 4-TB WD Drives using their smart array option that lets you expand the array dynamically. Great options with software applications that run right on this NAS box. Web browser based configuration, client apps for all PC,MAC,IOS, android makes this a very flexible solution, You can even use it as your network firewall, router, DHCP, SYSlog and media streamer.... And so on...
It will take a while to work my way through the device. From what I've seen of the docs - some are helpful and describe why you would use a function, others are the generic click this button to turn X feature on or off and no explanation on what the feature even does or why On is better than Off in the first place.Streaming - You can add media server, but I'm still trying to figure out what that is better than using it as an attached drive?Development - I see how I can install Wordpress and run a website - but as a developer, I don't see how I can install 5 Wordpress instances and use a vconf file to differentiate between them.Backup - Still not there yet.
Nothing more to say. Awesomesauce!Beats every other NAS I have had by a mile, and they keep adding features, for free! to the OS. Amazing!
I purchased the unit on May 14 and I am writing this on July 14. It is now too late to get a refund from Amazon. So you can say I am totally stuck and I have little choice if I am to keep the data.
Answer: Yes you can use as many or as few bays as needed I am currently running only two bays and will add more in the future.
