n00b to raid 1
 

I dunno what i did wrong this time, but i lost all my data in a raid 0 config this sunday.

No more (important data on) raid 0 for me anymore. :)

I've set up a raid 1 array (mirroring) now. How safe is this? I know it saves your data when one of your HD's crashes, but does it help agains corrupted OS systems due to heavy overclocking?

Can i detach a drive from the raid controller, attach it to an onboard IDE controller and have my OS running on a single drive at any time?

One final question: i though raid 1 had a small improvement in read speed when compared to a single drive, but i don't experience an improvement nor does HDtach show a higher seq read speed...?

the difference on a fast system is very small for read speeds.

the data on both Drives is the same, if one crashes the other one has an exact copy

you cannot hook it up to a normal controller & boot from it, since the OS is looking for its files on the raid controller

however, you CAN get the data from it when you install it as 2nd drive in another system
this is only an issue if you use a RAID1 as a system partition

I use it as a data drive, and as such you can always access it no matter it's hooked up to the Raid controller or normal controller

ps: :^D
I told you sunday afternoon that RAID0 is dangerous for precious data :)

Thanks for the info. :)

How about overclocking? Does it protect you against corrupted OS'es?

hmmm, i think i found the cause of my problems.

I bought 2 Seagate Cuda V 80GB last week. I tried installing WinXP in the raid 0 array 3 times. Each time it installed without a prob, but after a couple times rebooting my OS was corrupted (cfr high mem overclocking).

Now i've build a raid 1 array, and this morning i saw it was rebuilding disk 0 in the background. I just rebooted, and i see disk 0 is being rebuild again...

Conclusion: disk 0 is DOA?

-edit-
winxp was able to format the drives in raid 0, but win2k encountered an error... hmmm... must be dead drive.

i had a fuxored raid0 ... fixed in 5 minutes :^)

haha, the proggie is called raidrb ... how convenient

raid1 = same performance as single disk
have it on my server, never had data loss ... if you have good raid software (i have promise fastcheck utility) it rebuilds immediatly whatever disk problem you may encounter ... works like a charm
