raid 0 how dangerus - Page 2

post #11 of 33
RAID 0+1 maybe a better Idea as you get the benefits of RAID 0 but safety as your data is backed up. However I beleive you need 4x HDDS for this....not 100% on this though .

Raid 5?

Only need 3 HDD's then I believe. You don't quite get all the performance or all the security, but you don't have to pay all the price either.

It's kind of a compromise among all the points

It needs at least 4 hard drives.

use this formula:
(Number of drives x Capacity) / 2 = actual storage space.

It removes the things that don't matter (write speed) and increases read speed, which would slightly matter.

On topic: he only has 2 drives, so I answered your question, double the mean chance of failure. In response to your other question, there is nothing you can do, the risk is with mechanical breakage. File corruption acutally might be a concern, as overclocking the RAM and corrupting a file would cause you to loose all your files unless I am mistaken.

We know he only has 2 drives, but there is something he can do. He can buy more hdd's and go to Raid 10, 1+0, or 5 to fix the problems he could face.

In response to the post above mine, if one of your drives die, then you lose all the information on both drives. It's not that both drives will die at that point, only that all the information you had on them will be inaccessable.

No, you can always reformat the drive as long as it doesn't crash(as in break in side).

With RAID-o there is a greater the FATs (File Allocation Tables) can get messed up. And yes, NTFS still has FATs. they are just shaped different. With the FATs messed up the data will be un-readable by windows

i believe it's more common for the RAID array to fail than it is for one of the hard drives to fail. if you have an Intel chipset, you can download the Intel Matrix Storage Manager for free and it's supposed to monitor your array for you. i've never messed with it so i don't know how it works. i think i read somewhere that it can warn you of an impending array failure and possibly even repair damage sometimes? i recommend you read up on it before quoting me though, as i've never spent any time researching.

No. The Drives dont get physically damaged. The only thing to die/get damaged is the RAID array which is the software that merges both HDD'S into one. ( Very very simple explanation )
