RAID on a Compaq?

Is there any way to install RAID 0 on a Compaq Presario whether through the motherboard or a PCI adapter?

Edit: Also is it possible to install RAID 0 without deleting the HDD or having to re-install the OS?

You don't want RAID 0. Don't waste your time. You can do it with a cheap PCI adapter though. I just don't see why you would want to. It isn't any faster. It cuts the failure time in half. The only thing it can do is make two drives into one big drive. Well that's just great. One of the drives fail and you lose everything. Wonderful. lol
 
I'm sure there's a PCI RAID card out there if you really want the upgrade. Just look around places like Newegg. They have them in both IDE and SATA...

As for the OS, I'm not totally sure about that. It should be possible, but you must realize you don't have the RAID drivers on there now. You should be able to do something like make a ghost image of the current drive and just copy it over to the new drive, but you'd also have to be sure all the drivers are there and what not.
 
So if not RAID 0, how about RAID 1? I intially heard RAID 1 was faster until I read recently that RAID 0 was for 'gamers'. As for drivers, I kinda guessed I didn't have them since I bought OEM crap (Crapaq or Comcrap), yet, I have two SATA ports on my mobo, so is it possible through that? And is the ghost Other was talking about a backup or something?

What is with you and the Anti-RAID? its not that bad! have you ever tried it?
And to answer the first question, you could use a PCI adapter like so many have said.
 
I don't know the RAID standards right off, but RAID 0 is probably what you'd want(two drives acting as one big one) Just ignore SirKenin. It IS faster, but I don't see any need for it, personally. A few years back, it was nice for video editors and such, but drives/interfaces have gotten much faster now.
 
RAID 0 gives much higher average transfer rates then single drives alone. I bet you havent even had a RAID 0 setup, have you?

RAID 1 just mirrors the drives, theres no performance increase. However if you have RAID 0+1, you can the best of both worlds.

Yes, of course I have used RAID. I have benchmarked it extensively, I service clients with RAID arrays in mission critical applications and I have done plenty of reading on it. I also have had a RAID 0 array blow up on me and I lost everything. That was my AMD machine. Holy CRAP I hated that rig with a passion. Those XP CPUs were nothing but garbage.

RAID 0 is not a true RAID array anyways.

Baloney.

Here's some reading for you to do with plenty of benchmarks using Raptors in a RAID 0 config:

And here is the conclusion:

If you haven't gotten the hint by now, we'll spell it out for you: there is no place, and no need for a RAID-0 array on a desktop computer. The real world performance increases are negligible at best and the reduction in reliability, thanks to a halving of the mean time between failure, makes RAID-0 far from worth it on the desktop.

First off. Do NOT do RAID 0, nor 0+1. That is the worst thing you could possibly do to your computer if you care anything about maintaining data integrity.

The whole point of RAID 1 is to mirror the data. Redundancy. If you mirror it and stripe it, you're just throwing the whole point out the window.

Read the article I linked in my previous post. RAID 0 is practically worthless. The performance "increase" that people "see" is all in their heads. It isn't worth the risk, trust me. Been there, done that.

How is RAID 0+1 bad? You get the advantages of a slight increase in performance with the two drives in RAID 0 array, and then you have a backup of the RAID 0 Drive(s) on another drive. So if one of the raided drives in RAID 0 fails, you will have a backup copy.

And RAID 0 may not be needed for gamers, but they say in that article that if you use programs that benefit from a stripped array, it can be useful.

And never did I say that RAID 0 was worth it.
 
Think about it for a sec... If you use 4 drives, each pair striped. You gain a smidgeon on the stripe if you're lucky... Only to lose that and possibly a bit more with the mirror.

Doesn't make a whole lot of sense, does it. :)

Actually, I think RAID 0+1 is only 3 drives, unless im thinking of RAID 5...
 
To be honest with you, save for the case of mission critical applications, I can't really see the need for RAID at all. I find RAID to be a serious pain myself. I would just add another harddrive for data or something. If it is sensitive data, either do regular backups or consider RAID 1. That's my opinion anyways.
