asked on Ideal RAID configuration for a media server
Hello,
I am looking for the fastest sequential write speeds for large files (5 to 20 TB) with some redundancy. I am using Adaptec 31605 card with BBU. I have 12 2TB SATA drives to work with. I keep a backup on another server. These are my questions:
Should I use RAID 5, 50, or 6? (RAID 10 doesn't geive me enough storage for expansion)
Should I use 1024kb stripe size?
Will write cache help me at all?
If RAID 50 is best, what configuration will have fastest write speed? 3x4, 4x3, or 2x6
Thanks,
Tim

Thank you both. The RAID calculator was very helpful as well as the info on stripe size and Write cache
