from completed build Can I get a NAS with that?

Here is where I lucked out. I was watching these guys sitting at around $165 a pop when I got a newegg.com email with a 4 x 4TB for $599 offer. That just happened to be the size and number of HDDs that I have been looking at so ... I pulled that trigger. This will probably be way, way too much space for my needs (famous last words?).

Edit: Tried to register these HDDs with WD last night and they all got rejected. What is up with that? I'll call WD today and see what the issue is.

from completed build Home Media Server

To store all the data, I have two RAID 0 arrays setup with the 4x4TB drives (added in Aug, 2014). The main array is hardware striped for performance, the backup is software spanned. Although, RAID 10 is easier to setup, its advantage of lower array failure require six or more disks. I have decreased energy use and decreased latency due to less disks having to spin up on access. I spanned the 2nd array for two reasons; performance is not as important, and a spanned array has a better chance for data recovery in the event of a failure. At the time, there was a good deal on these drives on Newegg, and I did manage to get these from two different batches (by luck).
