What is RAID?

post #1 of 14
Thread Starter 
I have 2xCrucial RealSSD C300 at 256GB each and I was wondering if I would notice a significant performance increase in switching from default to RAID.

I am unfamiliar with what RAID is but would like to give it a shot. Can someone simply explain what it is/does? Advantages and disadvantages maybe? I would really appreciate it.

Also, to switch into RAID, do I do that from the BIOS? Do I have to wipe the drives clean again?

You're probably referring to RAID 0. The advantage is an increase in performance, the disadvantage is that if one of the drives in your array fails you lose everything.

Depending on your requirements you do RAID from within the BIOS as well as in Windows.

Redundant Array of Independent Disks

in simple way. you can use it as a backup or it can be runned like crossfire/sli for performace gain.
yes from bios. you need to set it there.
be aware that you will lost all your data on drives when you are making a raid (no matter what kind) if you have something on them.

Ahh so it's basically like a reformat when I want to set it up?

What do you mean "I'll lose everything if a drive array fails"? Like, I'll lose all my files and stuff? Or will the drive be a total loss? Or? Sorry I'm confused?

You would lose all of you data. Although if a Single Harddrive setup fails, you will lose all of your data so it doesnt really make a difference in my Opinion.

That's what I was wondering because don't you lose your data anyways if your hard drive fails? I've only really ever used one hard drive so when it's dying, I move it to my external beforehand.

So right now I have Windows 7 installed on one hard drive and all my games on the other. One is drive C and one is drive F. Is RAID just one drive or can I do the same thing?

if RAID0 then the advantage is speed......the disadvantage is since two 256GB drives become one 512GB drive(not physically, just as seen by the os), if one malfunctions the whole RAID0 array will disappear.....i use a 2TB drive to do regular backups of my RAID0 array

Oh okay so it's basically what I'm used to: having one hard drive. So I can't separate my files like I wanted to and install windows on one disk and all my files on the other? Like how does it choose what data goes on one disk and what goes on another because physically, one disk can't have 300GB so how does it choose what goes where and how can you tell?

Sorry for the stupid questions but it's my first time trying RAID :/

no problem.......a simple way to explain is that the data is split between two drives.....a piece goes here, and a piece goes there

Ahh so it's just random. Okay.

And I assume RAID will be significantly faster than my current setup? I have both drives plugged into the Marvell 6gb/s slot.

So it just reads as 512MB on drive C? Instead of 256MB on drive C/F?
