Everyone's home RAID is likely an accident waiting to happen. If you're using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I'm guilty of operating under this same false hope - I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails. The RAID controller can simply figure out the missing data by running the extra parity through the same formula that created it. This is called redundancy, but I propose that it's not. Since I'm also guilty here with my huge array of Caviar Greens, let me also say that every few weeks I have a batch job that reads...

I was ready to purchase HGST enterprise drives, the former Hitachi, but WD came out with these drives just in-time. I wanted to get the 3TB WD30EFRX version for my Synology DS212 NAS, but the price difference didn't make that much of a sense, and 2TB drives are more than enough for a few years of my home office use. I am very happy that these drives MTBFs are rated at 1,000,000 hours, they use less power, and they are cheaper than other enterprise drives.Upon receiving, I immediately installed them in my NAS. It took about 15 minutes to install DSM 4 and begin the inspection process. I neither chose Raid 1, JBOD, or SHR, and I took some online advice and created two separate volumes,...

(Sorry, Amazon--I got mine from that Egg vendor up the road...since they had a combo deal and free ship going) Upon installation, it took 7 minutes to set these two drives up in SHR. (Synology's "enhanced" RAID1 configuration)WD brands these as "NAS Drives" with "NAS Ware", and they're pretty vague in their descriptions of what that actually means. However, after using these, I'll just take their word for it. They appear to have the power consumption of Western Digital Caviar Green 2 TB Desktop Hard Drive WD20EARX, but have access...
