I'm looking to move my DVD & CD collection onto my computer to save space. I'm thinking it will take up about 15TB of storage space. After that, I'd like to have a little bit of room for growth... so I'm thinking in the range of 20TB. (My collection hasn't grown much in the last few years.) I've been hoping that SSD technology would come along faster than it has, but it looks like I'll be stuck using HDD for this setup. I'd like to do either RAID 5 or 6.

My motherboard (Asus Z97 Deluxe/USB 3.1) supports RAID, but it's a software RAID. I'll consider an internal RAID with a recommended RAID controller, but it depends on the price.

If I go external--which I probably will--I'm completely open to recommendations, including NAS. I'll probably use WD Red NAS drives, but I'm also open to suggestions there.

Less expensive is better, though I'm willing to spend what I need to in order to do the job right. Speed is not my biggest concern. Price, durability, and noise are very important.

I will be running both Windows 10 and Linux (likely Ubuntu... though possibly CentOS), so please consider compatibility.

Thanks in advance!

Edit: I'm just giving an estimate of how much space I want. The type and brand of solution is what I'm looking for.

IMO, I would skip parity raid all together. Its often mistakenly assumed to be a 'backup' and safer then no parity at all but in truth its only marginally safer when the drives are large. Rebuilds are super slow and restoring the data from backups is usually much faster. Plus raid 6 controllers are expensive, even used ones.

Provided you have the space I would do a raid 10. Data is safer, rebuilds are super quick since you are rebuilding only one drive as opposed to the entire array with raid 5/6 and used controllers are quite affordable.

* Im using 6TB drive for expansion ability as the controller are typically limited to 8 ports.
Eight 6TB WD REd drives@ 225 each =1800 (24TB total array size)
controller, like the IBM M1015, $125...

controller, like the IBM M1015, $125 w/cables.
Total is under 2k

eight 5TB drives (20TB total) would save ~$200


in contrast a decent raid 6 controller is about $750 used. Add six 6TB drives (24tb array size) at $225 and the total is ~$2100

The cheapest solution IMO is a homebuilt NAS.
Pc can be cheap (~$400) use onboard controller and Freenas w/ZFS and four 6tb drives (WD Blue since you dont need raid now) ...
total about $1200. The main drawback is you lose raw speed since you will now be capped at the speed of your lan. This is why fast drives are no longer needed either. 5400rpm is fne for using across the lan.


** Edit** In all cases you still need to backup important data, files you dont want to lose (like family pictures) to another device. Never trust them to a single device which could fail at any time. The more backups you have on different devices then the safer those important files are. Thank you.
