Solve : Raid 0 or Raid 1?

1.	Solve : Raid 0 or Raid 1?
Answer» Hi All I ordered (2) 500GB's for my new computer. What I got was the (2) HD's acting as one RAID 0. When I spoke to the Tech support I was told with thier help Ican change IT to RAID 1. I've done some research on RAID 0 and RAID 1. Now I'm not sure which is better for me. The resaoning behind the 2 HD's was to use one as a Backup drive. Is it difficult to make the change? This is for my home computer, used moslty for the Internet and saving Jpeg's. Any help in this matter will be greatly appericated.. Windows 7 is the OS Thanks DBThis link might help; http://m-techlaptops.com/raid.htm For you specific situation, I would recommend you do a RAID 1 setting which better suited for data backup.Hi Ironman Thanks for the fast reply. Would IT be a major "PIA" to change from Raid 0 to raid 1? DBYes, RAID-1 is mirrored, both drives are identical. RAID-0 is split between both drives. You will have to start over, create an image of your current installation & reimage back to 1 drive with the 2nd disconnected. When you connect the 2nd drive in a mirrored configuration, the drive controller will clone one drive to the other.YES!! It's going to be a major"PIA" to change over to Raid 1? I will have the company techs. on the phone with me, I think, they already some disk on is the Wind 7 OS and the other is what they PUT on my computer. The computer is not even 1 week old..My problem IS do I want to spend 2/3 hrs at the computer.. Thanks Again DBHi All SO? Is "IT" going to be a major "PIA" to go from Raid 0 to Raid 1 and would be worth the trouble?

Advantage: greater speed. Disadvantage: failure of either disk means you LOSE all[/] your data unless you had already backed it up to a third drive. Raid 1: data is written identically to multiple drives, thereby producing a "mirrored set": the array continues to operate as long as at least one drive is functioning. But you should still back it up. To go from Raid 0 to Raid 1 you need to: Create an "image" of the RAID 0 array onto another disk (e.g. a USB drive) Use the array controller's software to delete the existing RAID 0 array and create a new RAID 1 array Restore the image back on to the array Quote and would be worth the trouble? That's for you to decide. Do you want performance or reliability?

Hi Salmon Trout I did some research on Raid 0 n Raid 1, so I know what the basic differences between the two. I believe I would have the techs on the phone with me, would it take a long time to do?

I was told me may take 2/3 hours to complete. Could be a number of hours. sure. On another note, no RAID method will be a replacement for a proper backup. I mean, sure, it might help if one of the drives suddenly fails- but a lot of the time that you need a backup, it's because you need a previous version of a file or document, that you've changed. Also, if a file becomes corrupt due to program activity, it will be corrupt on both drives. etc.Hi All Thanks for the information regarding Raid 0 and Raid 1. I think at this point I'll most LIKELY be staying with Raid 0. Backing up is really not that important, although I would like to have some back up system in place, for my desk TOP and my wife's Lap top, just in case. What I was thinking about is an External Hard Drive setup. I have No idea how that would work. The desk top and Lap top are on a home network, we can share files and pics. So far I can't figure out how to access her hard drive , if that is possible? Thanks DB

DBHi All
SO? Is "IT" going to be a major "PIA" to go from Raid 0 to Raid 1 and would be worth the trouble?

Is "IT" going to be a major "PIA" to go from Raid 0 to Raid 1

Raid 0: a striped array with your data spread over 2 disks. Advantage: greater speed. Disadvantage: failure of either disk means you LOSE all[/] your data unless you had already backed it up to a third drive.
Raid 1: data is written identically to multiple drives, thereby producing a "mirrored set": the array continues to operate as long as at least one drive is functioning. But you should still back it up.

To go from Raid 0 to Raid 1 you need to:

Create an "image" of the RAID 0 array onto another disk (e.g. a USB drive)

Use the array controller's software to delete the existing RAID 0 array and create a new RAID 1 array

Restore the image back on to the array
