is 6 raptors in RAID 0 a good idea? - Page 2

post #11 of 35
The best thing to do is still to buy an SSD for your OS, and put your files on a multi-spindle RAID0 array (say 1 SSD and 4 x 2TB Caviar Blacks (expensive but better) or 1TB F3s (almost as good but much cheaper)). This will cost the same or less than your 6 drives but will perform significantly faster across the board.

I've read that after three HD's in RAID0 that the performance increase for each additional drive isn't worth it. Set up TWO arrays with three Raptors each.

Get 5 raptors and 1 SSD then. Just put + programs on the SSD and games on the raptor array.

raid 0 + 1 them problem solved, or if you want EXTRA comport RAID 1 + 0 them.

6 VRaptors in RAID0 will provide around 1-2MB/s random read/write.
A single SSD will provide 50MB/s random read and 150MB/s random write.


For sequential performance, 6 VRaptors would bottle your controller.... I'm guess something like 500-600MB/s on AMD?

A single Vertex 2 can do 250MB/s.




Besides, do you have 2.5TB of games?

Whatever you do if your doing RAID with more than 2 drives get a dedicated controller card.

The performance is much better, the chance of array failure is much lower!

RAID0 does not really need a dedicated controller.

Failure rate is about the same since the primary source of failure are the drives.
