If you create a mirror RAID on OS 10.6 on an older mac and then move the drives to a new Mac Pro, will the RAID array remain intact?

The RAID will remain intact. I cannot think of any logical reason why it would not. Not much help I know but that's my 2 cent's worth...

I am pretty sure it would, as long as the OS itself supports the raid type completely. I formatted the drives using Mac OS' Disk Utility, but they were originally formatted as RAID 0, and my computer seemed happy with that configuration even if it wasn't what I wanted and was probably done with a different version of OSX. You should probably check that the older mac does support mirrored RAID devices before buying, just to be sure.

yes, RAID 0 RAID 0 comprises striping (but neither parity nor mirroring). This level provides no data redundancy nor fault tolerance, but improves performance through parallelism of read and write operations across multiple drives. RAID 0 has no error detection mechanism, so the failure of one disk causes the loss of all data on the array.[9]

Not sure why you would want to do it that way. With mirrored drives you already have drive redundancy. If a drive goes bad, pull it out and put in the new drive. There are better ways to provide for offsite backup than to keep pulling a drive and having the raid rebuild itself.

Yes the unit has built in support for time machine. The unit defaults to raid1 (mirror) so while you have two drives it behaves (including space) like a single drive, but offers the best in regards to fault tolerant

Yes, I bought it for my MacBook pro, but make sure the external hard drive is compatible with it, my G-raid was not.

Using X-RAID is the only way to make that work. But you are limited to 1 volume, if you want more than 1 volume you would turn off X-RAID but you cant go back without reformatting your drives. X-RAID will manage your redundancy

You can, just make sure when u make changes back up your data first..... You can loose it, upon moving from say Raid 0 to Raid 5.

it rebuilds / clones exactly so if you clone your boot drive the clone will boot i have not tried to clone two raid drives to see if they will work in place of the original drives

i think proraid supports raid functionality, this is the one i have and i'm using raid 5the other one does not contain raid functionality and is just a straigt forward enclosure that will give you one volume per HD installed at least.

I can't answer that through a test, as I'm using a Mac Mini with a SSD internal drive that only holds the OS and the program files. All of my music, movies, documents, etc. are on the first external drive, the second is a back-up of the first drive, the third backs-up the internal SSD and the 4th is a time-machine back-up (I don't use the external in a RAID configuration). I can tell you that I do not notice any difference compared to my former MacPro that had internal bays. I just opened my photo library that holds more than 42,000 photos and can scroll through the thumbnails without any lag. I also have more than 23,000 songs in iTunes and when I scroll through that, there is no lag, and all the album artwork appears instantly. I recently commented to a friend who purchased the new MacPro (has not arrived) and ordered the DataTale thunderbolt enclosure that I could not tell I was using an external drive. I also use Aperture for photo editing (large RAW files) and there is no lag when editing. It's a great drive!

You might consider the HP MediaVault instead; which lets you set up and manage a Raid mirrored drive set easily via your PC interface and break the raid to put the copy into an Safety Deposit box. It uses inexpensive 500gb drives. I have two of them and they work great, super easy to manage compared to most NAS I have used.

rbohl is right. RAID 1 will give you 2 disks that are mirrored or copied and in sync byte for byte. Please use hot swappable hard drives in RAID arrays., Seagate and Western Digital (called RED model) have disks made for NAS devices. I would go as far as looking at the website for "approved" hard disks for the NAS you purchased. If one hard drive fails, the second is the backup in a RAID 1 config. The Synology will rebuild itself once the bad hard drive is replaced with a new hard drive.

I would say yes. I have multiple WD Hard drives attached to multiple macs with different Operating Systems on them... the OS really doesn't care what OS you have, so I would say you are good to go! Enjoy!! WD makes great products and you will be very happy with your purchase like I was! - Jeremy in TX www.MyMailBoxFreedom.com

Update-I did have to put in 5 old, dummy drives to setup the Raid 5 on the new box & then put in my 5 drives, in order of course, & the Raid came right back up. I just happened to have 5 old drives to use. Otherwise, I don't think you can do it any other way.

depend on yore RAID, can be done using JBOD if you use RAID0 to RAID5 every drive/s you add will have to be its own RAID

Right now I have a mirrored array on this PCI RAID SATA card with two 2 TB SATA hard drives. I am booting my Windows 7 Pro machine on a separate SATA controller on my motherboard from an SSD drive.

What you're describing isn't RAID, which by definition uses more than one disk. You're talking about disk mirroring, and even that makes little sense with a single physical drive. The whole point of both methods is to maintain data access when an entire physical drive fails.That said, you could set up a meaningful disk-mirroring configuration using this device and 2 of the drives within it. You would access one of the drives, and your mirroring would automatically write identical data to both drives in near real time, which is one level of RAID.
