    Stretch the budget a bit more and get a third hard disk! - Looking at the spec that motherboard supports Raid 5, so you'd get the speed and some redundancy.

    Making the assumption here that this PC was school property.. is it? or is it the deputy's computer that your building?
    It's a personal build for him purchased privately.

    There are only 2 SAS connectors though so could not use SAS and RAID 5 would have been nice. Could buy a seperate card though.

    In some circumstances RAID1 can be faster than RAID5 due to RAID5's increased overhead.

    You speak true words Jamo, I had this conversation with the head support guy at Fujitsu a few weeks back down in Bracknell, and he was saying that you shouldn't store your SQL log files on RAID 5 because it can slow the system down as it can't handle the throughput needed so its better to stick them on a RAID 0 or RAID 1.

    The spec of your pc is similar to one i built at the weekend, apart from the one i built had a 80Gb intel SSD, it got a score of 7.5 in windows, mighty quick for under £200.

    Slightly OT, but am I right in thinking that RAID1 will give you faster read (especially with larger files) and RAID0 faster write?

    Does the actual relative change vary much with controllers as well, compared to having the same drives in a non array setup will the performance difference always be of the same magnitude? (Taking for example two PCI-E x 16 RAID cards so the bus bandwidth is constant)

    RAID0 should be faster in most cases, RAID5 is supposed to be slower as it involves calculations of parity etc which RAID0 doesn't.

    RAID0 stripes data effectively storing one half on one physical media adn one half on the other.

    RAID10 is becoming more popular which is RAID1 volumes striped requires 4 disks min but has the best of both worlds.

    I must admit they are very quick these SAS drives. He tried 2 x SSD 2.5" drives in a laptop that was uber quick lol but the drives did cost like £500 each!
    I hope this deputy heads obsession with expensive gadget is at his own expence and not the schools.

    Can't help but feel that if you're gonna blow £400-500 on 2 x 300Gb SAS Harddrives you'd be better off just buying a 256MB SSD drive for the same amount of cash?

    Not sure about a 256MB drive, might be pwned by anything but Win3.1 lol
