Do I Need A Raid Controller?

Don't ask why but i need a minimum write speed of 248.83mbps and i was thinking of using 4 of these hard drives in raid 10 on this motherboard.

Is my on board raid gonna be able to handle that?

  1. You may not need another RAID controller, but you most likely won't achieve that level of write performance using 4 of those hard disks. You may be able to exceed the results achived at,2845,2334985,00.asp, but it would still be way below your requirements.

    Reading,2374-13.html might help you decide on the optimal solution (they used SSD drives). As you can see, the ICH10R performs quite well. Even a RAID 5 configuration using 3 SSDs would be fine. You should be mainly interested in the minimum write performance.

    Four 15K SAS drives on a caching RAID controller with BBS might meet your requirements, but it still would be significantly slower than SSDs.
  2. mega bits or mega bytes per second?

    If a good hdd can deliver 100MB/s average write and the F3 can average 115 then the max in a raid 0 is a theoretical 230MBytes/s average.

    You're looking at better drives. Or a proper array with enterprise equipment.
