I'm a noob when it comes to NAS, but gotta start somewhere and I could use a little help or direction. The more I dig and learn the more I'm just confusing myself as to what direction will be best. Here was my original plan... I have an old ASUS Maximus VI Formula with an Intel 4770k and 32GB DDR3 RAM https://pcper.com/2014/02/asus-maximus-vi-formula-motherboard-review/ From what I can see the board and chip have a total of 16 PCIe lanes available.... With... 10 SATA ports on board as well as... 3 x PCIe 3.0/2.0 x16( x16 or dual x8 or x8/x4/x4) 1 x mini-PCIe 2.0 x1 3 x PCIe 2.0 x1 I have 4 (four) Dell R1DNH PERC H310 cards available (still need to flash them for IT mode). I'll be using an old graphics card in the system as well since I have a few laying around anyways. Probably be something like a GTX 980ti or similar gen GTX Titan card. As for HDDs... I'll be running a 2 parity setup with two 18TB drives. 4x 8TB 6x 12TB 6x 14TB I also have a couple small 64GB SATA SSDs (if I remember correctly), but I haven't found the box they're in yet, lol. Was thinking of using those for cache drives. With that, I'm also leaning towards running a basic RAID10 in my current desktop with 4 of the above drives for a second back up. DATA will be a large video (TV/Movies) collection. game installers, pictures, music, and backup images of mine and friend/family PCs. At most 4 simultaneous users streaming video over home network with the potential for 1 additional user over the net. Transcoding isn't needed and I have no plans for Plex, but that could change if I see value in it.... But doubt it for my use cases. I have no plans to run games or video edit or anything like that over my network or for this system (I have a way better local build for that stuff). Beyond the watching of random 1080p videos the rest is basically just rarely accessed backup data. So... That all said.... Is this hardware reasonable for my use case? Will performance be okay if all 5 people are trying to stream 1080p content? ... Or... Must I start considering a new CPU/Mobo combo like a used 2nd gen Threadripper or Epyc setup? Alternatively on the "worse/older" side, I have a couple Core 2 Duo systems sitting around, but feel that's getting a bit too old for my needs even as just a NAS. I'm trying to be as cheap as possible for my first forray into this world, but also don't want a new system every two years because the hardware is too old to keep up. I really appreciate any help and thank you for taking the time to read and assist. Edit - oh and in terms of getting data on/off the UnRaid. Some smaller stuff will probably be sent over the network, but I'm usually just pluging in a USB drive to copy data back/forth as needed so pretty sure my 1gb eithernet should work well enough.
