Raid question

Ok i just finished building my new system, I7 920, Asus p6t Mobo, corsair 1000w ps, Corsair 6gb tri chan 1600 mhz ram, Dual gtx 285, and one 1tb baracuda HD 32mb chache, So here is my question, They only had HD in stock will be getting another on Wednesday, I installed win 7 on the 1 HD, When i go on wednesday to get the other HD do i need to completely reinstall everything to set them up under raid 0 or will it automatically copy what it needs to to the other drive?

Sorry, but such a nice system merits an SSD - 60GB is enough for the system. That is many times faster than a Raid setup and you can use one of the HDDs for imaging the system from the SSD and the other one for data. If you look at one, make sure it has Trim support in the firmware. This together with Win7 would be awsome. Random access on an SSD is typically 4 nanoseconds - on a HDD it is 20 milliseconds - that is 5000 times slower. And a good SSD has a transfer rate of 200+MB/sec.
BTW: Raid0 is not very safe. If one drive goes on the blink, you loose everything.

60GB is plenty for the OS and the programs plus the files that are timing sensitive (which are probably only a few). The performance boost with the SSD should be considerable. I have measured a 10 second boot with an early Win7 version. Even if it were 15 seconds, that would beat any spinning disk. There is no piece(s) of hardware for the equivalent money amount of an SSD that can increase the performance like that. But just to remind you again - Trim support is important to maintain the initial performance.

Ok so maybe i will go ssd in the future and i appreciate your input but money wise i can only afford another hd, So back to my original question, Can i just make a clone of original HD then hook up as raid 0?

noone can tell me if poss to clone another HD so i can set up raid without reinstalling os

I did not want to drop this conversation. But to tell you the truth, I don't know the answer to your question. Sorry. Maybe someone else does.

You cannot setup RAID0 without a reinstall as far as I know. Reason being is that 1/2 of the file is typically on 1 drive and the other half on the second drive. So, since you are already fully installed on one drive, it cannot simply split the files in half. You are going to need to reinstall.

Do you think I would even notice a difference other then maybe start up time by using raid? And if I do decide to go ahead and reinstall to use raid 0 I hear there is a prob installing win 7 with 2 tb worth of HD space, Is this true?
