Why RAID 0?
Because RAID 1 is mirror and RAID 0 joins 2 or more harddrives together.
I have about 3TB of data, and a single 3TB is not worth it. (The sweet spot is now at 2TB, right?)
So, I am getting two 2TB hard-drives and plan to join them in RAID 0.
Unless you know another way to join 2 hard drives together?
3TB of data... holy cow. I've been shooting digital photography for the last 10 years including RAW, & 1080i / 720p video for the last 6 & with triple backups I have less than 3TB of data. I have all of my originals on a single 1TB HD with 28% free space & that includes over 150GB of Audio files, & another 30GB of saved documents. Guess I need to take more photos
If I had 3TB of data, there's no way I'd put it on any RAID(other than RAID-1), not even with a backup of the RAID array. Personally, I find it much easier to organize using 2 separate data drives. Windows programs & games are installed on a pair of 120GB SSD's in RAID-0. I then have 2 1TB drives setup. On the newer/faster SATA III 1TB drive, I have 100% of my video files. On the older/slower SATA II 1TB drive, I have all of my documents, my music, my photos, & my downloads, but at the rate this one is filling up, I may move the downloads over to the Video drive since I can't afford 2TB drives right now...
Unless you're lumping everything into a single folder (which would be highly un-organized), there's no logical difference between running the drives individually & putting your files in their appropriate folders Vs spanning or RAID your drives together & putting your files in their appropriate folders... except that you run the risk of loosing everything if your RAID fails.
With 3TB (& growing) of data, I have 3 words for you... Network Attached Storage
. I suggest something in the 2 to 4-bay / $200 to $300 range like http://www.newegg.com/Product/Product.a ... 6822148615
This gives you the flexibility of external backups & unlimited expansion, as well as a centralized backup point if you have more than one computer.
