I am thinking of building a NAS server for secure backups, and for more storage for the MS. Can anybody recommend one, and why you recommend it? Using a media server for storage for the MS, do I really have to worry about CPU power on the NAS, or is there anything special I should be looking for? Thanks!

Two that I'm looking at are: http://nascompares.com/tag/wd-my-cloud-pr2100/ or https://www.windowscentral.com/synology-ds218-review or would it be better to get a 4 bay version? -
If you want secure backups get a real backup solution. Unless you're mirroring your drives, using a striped RAID with two drives will double your chances of data loss.If you want striped RAID use a minimum of RAID 5 with 3 drives. RAID 6 is better option with higher capacity drives. If it's merely for backup then RAID 5 should be okay if you can be without the storage if you have multiple drive failures and need to rebuild the RAID from scratch. This will also mean complete data loss of your backup. I have a Synology DS2415+ with the additional expansion bay (23 drives +1 hot spare). It takes over two days for it to rebuild the array when replacing a failed drive.Comment

I'm with duc135@gmail.com. Firstly, keep the hands off WD NAS. They are much slower than for example Synology NAS. Even though they are also equipped with Gigabit Lan. Synology NAS are very comfortable to run. You can manage such system from your browser. Usually there is no need for cryptic command line fumbling.
If you do not need such big NAS with 12 bays (Synology DS2415+) there are several smaller combinations (all Synology).
DS 918+ = 4 bay NAS, can be expanded by one 5 bay expansion unit DX517 (gives you 9 bays)
DS 1517 = 5 bay NAS, can be expanded by two 5 bay expansion unit DX517 (gives you 15 bays)
DS 1817 = 8 bay NAS, can be expanded by two 5 bay expansion unit DX517 (gives you 18 bays)
In addition, you don't have to start all bay equipped with drives. You can start with 2 drives in RAID 1, with an additional drive you can migrate to RAID 5 and with another additionl drive you can migrate to RAID 6. There is no need to start with expansion units. Not until the actual NAS runs out of bays, you connect an expansion unit with the next drive to add more space.
The initial investment is higher with a DS1817. But the more drives are installed it gives you the better cost/performance ratio.
I have a Synology DS1815+ with one expansion bay (18 drives each with 6TB in RAID 6) and a Synology DS1515 (5 drives with 6TB in RAID 6). I can confirm the long duration when it comes to rebuild the array because of adding further drives.
The big NAS is used for video streaming using a fantec media player and for audio streaming using a USB digital to analog converter.Comment

Thanks for all the info duc135@gmail.com. and wgk.derdicke! You both have definitely given me something to think about!Comment
