Hi,

Is it possible to migrate a RAID0 made of SATA drives to USB or FW without loosing the array?

Basically my desktop died and I have this array of 3 drives in RAID-0.

Now, I am thinking of getting 3 SATA->FW or USB and power up that array again via USB or FW.

Is OSX clever enough to recognize the array and drives order?

Nope.

You're going to need to re-create the platform, with the same software, to gain access to that RAID.


B.

that is no good ...

that mobo does not exist anymore.

i was hoping that OS X would automagicly recognise the RAID information off the drive and be able to reconstruct it. I know that changing the interface might be a bit of a problem, but in the worst case I could simply build another system that would support SATA to allow to "migrate" the data to another external RAID ...

Would this work instead?

I reckon that might work. I have been doing some research on RAID recently and came across a guy who said he had a RAID 0 that he had migrated over several different Macs. I'd be wanting to have a backup though. You'd have to be insane to have a RAID 0 without a decent backup!

You're right, but 700+gb backup storage doesn't come cheap.

Specially that this is only part of the data I have. I still have one 500GB, plus 1x 250GB, 2x200GB plus few more that are pretty full too.

Mostly Photo+Video, software backup, music, and other stuff.

Moral of the story is: don't keep stuff that you will regret losing on a RAID-0 partition that is not backed up

Well Guess what, it worked no problems on a different mobo/cpu... Just hooked up SATA2,3,4 as on the first mobo and then booted the system and VOILA !! RAID HD showed up on my desktop.

Now, I still havent tried on USB but somehow my old machine started to work again, don't know for how long but for now it works.

Well, that guy was right then! Well done...

Ok, more on this, I even experimented but reversing the SATA ports order and still works no problems.

Now, still have to try using SATA2USB adapters and trying if it still works.

I might actually go first by moving a single drive to USB and see, I bet that if this works it will all works... but that is a very long shot.

Just wondering why you want to go to usb 2? would be fairly slow for a raid device

Has an interesting comparison chart of thru put (Fibre Channel looks a lot of fun!)

Yeah... I reckon trying to use USB for this will just end in disaster. Anyway, good luck. Let us know what happens...
