I'm intending to built a FreeNAS-based storage server for a maximum of two simultaneous users in a 1GBit/s home network. Data will usually be written to the system only once and reading happens only occasionally. It shall store movies, music, audio books, etc; so it has to be huge. However, it also has to store important personal files like images, documents, scans, and work-related stuff; so there is need for parity. There won't be any encoding or similar stuff done on the FreeNAS; it's pure storage. Also there will be no jails.
The plan so far is to buy a 12-bay case and fill it with 12x4TB drives. Than I'll put them in a single RAIDZ2 vdev inside a single pool and be done. 40TB of useable storage space is perfect. RAIDZ feels a bit insecure, because when one drive fails the second drive follows hardon the heels of the first. And RAIDZ3 is a bit too paranoid.
Budget: 2,200.00€ (absolute maximum!)
With that budget everything has to be built on consumer-grade hardware, except for the ECC RAM and ECC-supporting components. So far I'm targeting the Seagate Desktop HDD 4 TB ST4000DM000 drives, as four of them run smoothly for many years now in my desktop system. And they are cheap! One bills at 125€, and when I buy more than 10 pieces I'll get a 10% discount. So 850 Euro will be left for the case, mainboard, CPU, RAM, SATA controller, etc.
So far I'm considering this setup:
MB: Supermicro X11SSM-F --- 232€
CPU: Intel Xeon E3-1230v5 --- 210€ (The Xeon E3-1240v5 would cost 379€!)
RAM: Crucial 16GB DDR4-2133 reg ECC --- ca. 150€
SATA: AMCC 9650SE-12ML PCIe SATA2 Raid Array Controller (used) --- 70€
PSU: be quiet! Straight Power 10 CM 500W --- 108€
HDD: 12x Seagate Desktop HDD 4 TB ST4000DM000 --- 1350€
Case: I'll use one of my old big tower cases.
---> TOTAL: 2,120.00€, leaving 80€ for shipping costs.
So the question is: Is this sane planning?
Btw: I already have a powerful(!) UPS for my router and my home server (runnig a Tor node, OSCam, JDownloader, CCTV), so there's no need to spent money on this.
