Blindsay Posted February 22, 2018 Posted February 22, 2018 Hey all, got unraid running on my new 8TB WD reds (4 of them total so 24TB) usable but i have like another 22TB of drives not being used but they are a mixed bag in terms of drives. I hate seeing them go to waste but i wasn't sure if it was important to have a matched set. In addition to the above i have, WD Blue 5TB WD Blue 4TB Toshiba X300 5TB Seagate 4TB HGST 4TB A lot of storage just being wasted but i wasn't sure if it was a good idea to mix them all in (although i was thinking of using the Toshiba as a scratch drive outside of the array). I guess if i was really worried about the performance of the slower drives i could keep things like SD TV shows on the slower drives and HD stuff on the better drives? not sure if that really matters though. On the hardware front i have 2 very different platforms available. Ryzen 5 1600 16GB DDR4 3200 Gigabyte aorus ga-ax370-gaming k5 Dual E5-2670s (V1) 32GB DDR3 1333 ECC Asus Z9PE-D8 WS (the onboard intel sata ports have died, the non intel work but it also has 7 PCIE slots for addin cards) Looks like roughly the Ryzen is equal to about 1 of the E5's but i could always upgrade those to like Dual E5-2680V2's pretty cheap. The Ryzen setup should be significantly more power efficient. It will just be running a big plex server (trying to stick to all H264 content since H265 abuses cpus), A minecraft server and my torrent box (which actually makes pretty good use of the 2 cores i gave it) Just trying to find the right balance between having plenty of power, but not costing a fortune to run etc. Thoughts?
whipdancer Posted February 22, 2018 Posted February 22, 2018 Use what you want. You can see my sig for an example of mix and match. Sizes in use all at once have ranged from 1.5tb to 4tb. I've slowly been upgrading, smallest drives first so that I'm basically a mix of 3tb and 4tb drives. I have an 8tb drive that I will add when I get a chance. What's a pretty big plex server? (I currently have 2500 movies, 10k tv episodes + music, photos). Currently at 34TB used out of 44TB.
tdallen Posted February 22, 2018 Posted February 22, 2018 You can certainly mix and match drives in an unRAID array. Keep in mind, though, that in the event of a disk failure unRAID needs the parity drive *and all the other drives in the array* to reconstruct the failed drive. In other words, don't put failing disks or disks you don't have confidence in into the parity protected array. The 4 and 5TB drives you have should be more than fast enough to server HD content.

Putting a disk in the array that you don't need to use is adding risk for no reason, and increases heat and energy usage.

Thanks, I havent finished ripping my movies yet so i only have like 500 movies on there so far (should end up at a little over 1k) about 10.5K tv show episodes. 15/24TB used, i do have another 8TB WD red on the way though On 2/22/2018 at 10:38 AM, tdallen said: You can certainly mix and match drives in an unRAID array.

Thanks, good to know about the empty disks, i was about to go crazy adding drives lol
