hi again everyone

well 2 quick questions please

one ive got a 1200W NSP Modular Power Supply on my computer but it got shipped from the usa

our electricity is 240 as opposed to the 120 used in the states.

but i cant find a switch on the power supply to change it from 120 to 240. i dont want to fry it :)

ive been told that the power supply  universally adapts to the incoming power 110/240

never seen this before so just confirming wth the experts.

 

and the second question was about hard drives

which would be better?

2 150G Raptors (Raid 0) and 2 750G (Raid0)

or

4 150GB Raptor HDD + 1 750GB SATA HDD

thanks again

Your PSU question I am not sure.....

The HDD question I can offer advice however; first I would like to ask: why two raid 0 setups in the rig? Generally you just put a raid0 together on your bootable HDD(s) that have your programs and widely used applications on it. If you want pure raw speed, setup your 2 150G Raptors in a raid 0 and use a 750GB HDD for media storage. If you REALLY want to go all out, grab yourself 3 raptors and throw together a raid 5 setup (striping + paridy).

In summation....its complete overkill in my opinion to setup 2 raid0 setups on a single rig

yea i dont think u want to have but in raid 0, u might just want to run the 750 in raid 1. cause if 1 of the drive fails in each raid 0, you would be kinda screwed [:'(]

Cannot answer the power question for sure.  I would be suprised if the unit does not have a label that defines voltage input values.

 As far as the hard drive setup, if you are looking for performance rather than reliability then RAID 0 is the best approach.  Understanding of course that single drive failure in that config is a total loss.  Most testing has shown that more than 3 drive in RAID 0 start to show a degradation in throughput as opposed to 2 or 3.  I agree with the other comment that placing two other large drives in RAID really does not accomplish much.  I would go with a single 750.  I would also setup the swap file to that drive only and leave the RAID 0 to OS and program install only.  I would stay away from RAID 5 if you are looking for peformance with normal SATA drives and onboard RAID controllers.  If you were using a performance add on RAID Controller and 15k rpm drives it might be different.  Just my thoughts based on testing of many rigs....

Posted an answer to your memory issue as well...

About the PSU, I would contact the manufacurer and ask them. probably the safest bet

My philosophy on Raid 0 is that is great for the OS drive ONLY. If you are going to run a raid 0 configuration make sure all yoru data/programs are on a sepearte physical drive. Also make sure you cool the drive since they will get hot

CHEERS EVERYONE

BUT FOUND OUT THE POWER SUPPLY WAS UNIVERSAL SO AUTOMATICALLY DETECTS AND ADJUSTS THE POWER INPUT AND OUTPUT
