Mac Forum / General / Hardware / August 2007Built in Raid w/MacOS X
Let me try here, as nobody on c.s.m.s had anything to say.. Anyone have any experiences with the SW raid available within disk utility? I'm considering a HW raid1 external enclosure but would just get a couple of drives if the built in raid1 is sufficient. Any thoughts? experiences? thx -- thepixelfreak  Signaturethepixelfreak >Let me try here, as nobody on c.s.m.s had anything to say.. >Anyone have any experiences with the SW raid available within disk >utility?

I've NOT tested to see if the system will boot/recover with either drive damaged. You have to jump through hoops to get the auto-rebuild enabled. There's needless confusion as Disk Util's setup. You have a pyramid: slices of RAID RAIDed volume filesystem in Disk Util.... Both filesystem and RAIDed volume offer you RAID options and OPTIONS under same; it's not clear which you need. See the Apple Kbase note 106987. Note X.4 RAID differs from X.3.9; you must use a shell utility to convert. In short, start with 2 expendable drives & be prepared to spend some learning time. Also note: If you use Target Disk Mode to mount the drives on another box; you'll see the 2 slices, not an array. Changing one shall break the integrity. Hopefully it recovers later... Do you have a external RAID box? What's it cost?

Just a repository of disk images of user directories and iPhoto database. > You have to jump through hoops to get the auto-rebuild enabled. > [quoted text clipped - 19 lines] > > Do you have a external RAID box? What's it cost? I've been thinking about this thing.. http://eshop.macsales.com/shop/firewire/usb/raid_1/Gmax Maybe just the enclosure for $149 and I can get some cheap sata drives elsewhere.
