Hi Lance, >IMPORTANT NOTE: It is critical to have matched drives for best >performance. This means that all the physical details of the disks >should be the same, not just the drive size. Number of platters, seek >time, etc. Yep, it is much more efficient distributing tasks between drives if they all perform exactly the same. >An example of a nice solution with the FastTrak card is 4 drives. >You can then stripe the drives in pairs and then set one pair to mirror >the other for redundancy.

[Gives 52 gig, factor 4 write speed] How about RAID 5, using just one drive's worth of storage for redundancy? You get 39 gig of storage, no data loss or work stoppage should a drive fail, and write speeds ranging from factor 2 to 3 depending on how smart the controller is with bulk data. Cheers, Thomas
