New home server (RAID) to replace aging one

Good morning!

Ok, so, back in late 2007, I built a RAID 5 out of an old Dell machine and 5x500 GB HDDs (2TB RAID). My buddy set up a linux build on it to serve as a home server for my personal movie and music collection so I could link it to set-top boxes and game consoles throughout the house. Long story short, it's 7 years old (no failures!) and slower than I want it to be, linked up to a slow tower with high power use. It has never had any issues with payback speeds, but the read/write speeds are slow, and it's a big power drain. I'm also running out of room.

I already have a 2 TB drive I'm COPYING everything over to (not offloading, a true 1:1 backup) for when I eventually build the new machine. My plan is to buy the least expensive, lowest-power solution, while still having drives that have the potential to last 7 years again. Preferably, I'd love to buy a backbone system that 5-6 years from now, if the RAID fills up, I could actually just use the same tower and upgrade my storage capacity without worrying about speed.

Anyway, basically, I have 2 questions: 1) What is the smallest form-factor, least power-hungry mobo/CPU/RAM combo that would allow me to continue on with a RAID 5, and 2) Are the WD Red drives worth it for this type of situation over the "Green" drives that are slightly cheaper? I was hoping to do 5x4TB for 16 useable TB in RAID 5.

Also, (I guess 3 questions) is a windows built-in OS inherently "worse" than doing linux again? I mean, linus would be a smaller footprint, run with less crap, and be less prone to a virus on the RAID, since it is internet-connected. Thoughts?

You're welcome.



My FreeNAS server is running on a Gigabyte Z68 motherboard, an Intel Core i3-2120 CPU, 8 GB G.Skill RAM at DDR3-1866. Unless you need to transcode video on-the-fly while streaming, a setup similar to this should be more than adequate.
Linux has its advantages for this. Now I use windows for my file server but my security camera dvr software and other software is windows only which is why I chose windows (otherwise it would already be migrated to linux).

While you can get a very small motherbaord, you still need the same amount of storage space for your drives so doing a mini itx board does not help you in any way as any case big enough to hold more then 4 drives is going to be a mid atx tower.

What I have for a case is a Fractial Design Define R4 which is a mid tower case. Its not small by any stretch, but its more wide then tall. What it does have though is 8 internal hard drive bays, so you are covered for any expansion.

For strictly file server you could go pentium + b85 board + 4gb of ram and have enough "horsepower". Now if you think that your needs will grow in the future I would go with an i3 and 8gb of ram.

As far as the which level of drives go: If doing raid 5 or 6 then I would go with the red series as they are better deisigned to take to beating. If doing raid 1 or 1+0 then the blue series drives are fine. I would not do green serries in any raid array.

They make solutions for windows and linux for software raid as well. Here in the next few months I will be switching to a windows software called flexraid. This allows me to merge multiple drives into one volume, and allows me to assign a drive as a parity drive and also allows me to expand whenever I want. While using more softwae overhead the other bennifit this gives me is that it is much less stressfull on the drives as the data is stored locally on each drive (so JBOD) so thus worst case scenario I lose only the data on that drive, not the whole raid array.

If you're using software RAID, then Green Drives are fine. Hardware RAID is more sensitive to error-correction timing, which is what the RED Drives are for. I'm currently running a FreeNAS server with three 2TB Green Drives in software RAID 5, works flawlessly.

This is EXACTLY what I was looking to find out from this part of me question. Thank you for this. So, software RAID somewhat negates the need for a "Red" drive. Thank you.

So, any specific recommendations, if i decide on the i3? Like, whenever i buy, i try to get to the price point that has all the features and reliability I need for a server, but not to the upper-end where the price-per-improvement ratio starts to taper off, you know what I mean?
