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.

It's a personal build for him purchased privately.

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.

Hmm im interested to see what this one gets then. Its guna get W7 x64 on it 2mz!

My mistake, i doubled checked last night and it has a score of 7.7
23rd March 2010, 03:14 PM #23
Its all done just need to run the score checker on it which I have forgot to run!

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 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
