Raid0 Question

post #1 of 10
Thread Starter 
Hey guys,

I currently have a WD1002FAEX (1TB Caviar Black), it holds my OS, steam games et cetera. I've just ordered another identical drive, and my question is;

How can i create a RAID0 array without losing the data on my current drive?

I don't have another drive to transfer it to and the case i'm getting soon (Antec P180 Mini) won't have room for 3 drives because of the way i'm planning the build, so buying an extra backup drive is more or less out of the question.

Any help would be appreciated, thanks biggrin.gif

There isn't a way that I know of that you won't lose your data.

I advise against it. You have no back up drive. If the array goes all your data is gone. I suggest if you do set up RAID then set up a RAID 1 array, otherwise don't bother.

I don't want a Raid1 array, i want a performance increase not drop. I guess i'll just have to find a way to put a backup drive in the P180.

just get a ssd, WAY faster than HDDs in RAID 0 anyways. rolleyes.gif

Use one drive for data and another for backup.

Also i think those drives have raid issues...some WD drives do at least

Those drives DON'T have RAID issues. They are just not made for RAID like WD RE4's.
Just set up your RAID0 array (it will be much faster), but you MUST get another drive for backup.
I just run a manual backup every now and then to it. Don't need a RAID1 setup (which will slow things down)

I never noticed a slow down from a single drive to raid 0. I run raid 0 on my server and I actually get increased performance over a single drive in reading, and isn't that what we do for the most part. Especially for the average user not like he's looking to host a SQL DB off it.

Remember that if you choose to do RAID0 the likelihood of you losing ALL of your data doubles. That is a 100% increase in likelihood that you will lose everything.

Not trying to say don't do RAID0, because I do it as well, but make sure that you have a backup drive (internal or external) that you can regularly back up your irreplaceable data to.

You never realize how much you need a file until you get a drive read error. tongue.gif

I work with RAIDs quite frequently, and have run into this several times before. How much space do you need? Are you after 2TB of space, or performance? I read that buying another drive is out of the question. I strongly suggest reconsidering this. It is always good to have a spare drive, especially with RAID 0, even if it is not in the case. I have stacks and stacks of HDD's sitting around with clones on them, which will make sense shortly.

If you're after performance, I'd suggest getting two 500GB WD Blacks, instead of the 1TB. Install the two 500GB drives in the new case and set up the RAID 0. Connect the third drive to a different SATA connection. Then use Acronis, Ghost, or any cloning software, and clone your 1TB drive with your OS and such onto the RAID array. Now you successfully have your RAID 0 array, and a perfect backup of the array should one of the drives fail. Now, remember, I said I have stacks of drives? I frequently clone my RAID arrays to a single drive for archiving (granted, these are multimillion dollar projects and not just personal data). So, now you can clone your RAID 0 to your 1TB drive as frequently as necessary to prevent losing all your info.

If you need more space, then you can fuss with the HDD sizes. RAID 0 = 180-190% capacity of the drive size. Just have a spare backup drive that fits the entire size of the RAID 0. (i.e. Two 1TB drives in RAID 0, One 2TB backup.) One last thing, keep in mind, a simple WD Green would work well for the backup drive, you don't need a high performance drive for archiving. Essentially, you could clone your 1TB drive with your OS, to a 2TB Caviar Green, then clone the Caviar Green to the RAID 0 array with the two 1TB Caviar Blacks.

Hope that helps!

Check if the AMD RAID interface allows you to migrate to an array.

Intel drivers let your do so.

It's not quite 100% but it is close.
