Morning all,

I am planning to build a freenas home server. The spec's I've picked are the following and want to make sure I'm not doing anything overly stupid. My main use will be to store recorded TV Shows and movies (I use a CETON USB to get the cable signal to my windows machines) for use across my network. I will also run sickbeard/sabnzbd on the freenas machine.

Motherboard: ASRock H77 Pro4/MVP LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
CPU: Intel Pentium G860 Sandy Bridge 3.0GHz LGA 1155 65W Dual-Core Desktop Processor Intel HD Graphics BX80623G860
RAM: 16GB (2 x 8GB) DDR3 1600 (PC3 12800) --- Should i go 32gb?
USB Drive to run freenas from: Patriot Supersonic Xpress 8GB USB 3.0 Flash Drive
Hard drives: Four of the following: Seagate Barracuda 7200.14 ST3000DM001 3TB 7200 RPM 64MB Cache SATA
I already have a good power supply and case from my last PC build.

I was planning on doing ZFS1 with the four disks but I've been reading some that I should have either 3 or 5 disks for a ZFS1 build, so would it be worth spending another $130 for a total of the five disks? or would that money be better off on a faster cpu or more ram?

thank you very much for any comments!

noobesauce80 has an excellent starter guide at http://forums.freenas.org/showthrea...explaining-VDev-zpool-ZIL-and-L2ARC-for-noobs!

RAIDZ1 should have the total number of drives equal to 2^n + 1. (ie 3,5,9, etc. drives for the vdev)

RAIDZ2 should have the total number of drives equal to 2^n + 2. (ie 4, 6, 10, etc drives for the vdev)

So, go with RAIDZ2, or add a drive and use RAIDZ1. How important is your data to you? Otherwise your hardware looks ok, though I would recommend an Intel nic added to the board instead of using the onboard Realtek. Something like http://www.newegg.com/Product/Product.aspx?Item=N82E16833106033

Thanks for taking the time to reply BakCompat! I will take your advice and add a 5th drive, my data is mostly recorded TV so it is not very important. I already placed my order for the parts this morning but if my network performance is bad I will buy that NIC. Thanks again.
