Is it possible to mirror a RAID-0 array to a single drive?
For example, I will be setting up 3x1TB on a RAID-0 (striped) array and i want to mirror it to one 1TB drive. Is that possible or do i have to resort to Time Machine ... ugh
and YES i've already STFA! no answers as of the start of this thread

-edit i assuming Time Machine backs up the "volumes" and not the "drives"
Well,finaly it's bootable and raid bootable.Does anybody know is ti bootcampable?I just come back from windows,I find I lost so much,I can't even use foobar2000 and my 9800gt.
Difficulty deciding between 1 or 2. Unsure about real world performance gain of 2. No experience with SSDs or RAID 0. Worried about alignment and sleep/hibernate issues. Stock 5400rpm 320GB will go inside eSATA enclosure. Does anybody have a good eSATA ExpressCard/34 to recommend? I don't care about the SuperDrive. But I'll keep it for Care warranty purposes.
Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?
Lastly, are the highpoint 3500 series a decent card? and fully compatible?
I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?
I'll be going with the OWC SSD(s) ExtremePro for the boot drive................ either a 2x60 OSX SW RAID 0 or single 120. I'd rather err on the side of safety but always looking for more umph If going RAID 0 would it be advised to go with a dedicated controller?My data drive will be 2x1T RAID 0.
My current setup consists of my boot drive (250GB), a striped RAID (500GB) for storage and a 1TB Time Machine Drive.I have recently bought a new 1TB internal drive and would like to replace the striped raid with this drive, thus freeing up two 250GB drives - 1 which i will keep internally and the other will go into a external enclosure My question is can i just copy the files from the RAID to the new internal or do i have to use software to clone it?
I have a Early 2008 Mac Pro. I have the Apple Hardware Raid Card Installed. I have 4 2TB disks installed. Currently I've got the system disk setup in Bay 1 as a single disk. Then I have the disks in bays 2 through 4 setup as a raid 5. I've been thinking that I might be better off to make all 4 disks into a raid 5 array and then just make volumes for the system disk and my work disk. My goal is to have a system volume an a scratch/work volume for image and video editing.
I have a bunch of Mac Computers here and I want to make a file server for them with about 5 drives in an RAID array to be a little bit secure. I am fairly certain how to go about and build myself a basic file server for a bunch of PCs networked together, but I am not sure about how to do it for a network of Macs.
i have Snow Leopard running in a RAID, and just a separate single drive installed for windows 7. Problem is, when i try to go to bootcamp assistant, it tells me that RAIDS aren't supported in bootcamp. I don't want to install it on my raid, just on the other single drive. Does anyone know a workaround or how to do this?
I have two choices. 1. Apple's Mac Pro RAID Controller, Four Drives, RAID 0+1. One big disk, highest cost. 2. Or, some other RAID Controller (?), Three matching drives, RAID 5. Then, 1 big drive for OS/Applications/Time Machine.
I'd probably move my Home folder to the RAID Array and have just my data striping amongst those drives. Has anyone had a dilemma like this before? I like the idea of hardware separation of my Home folder from the OS.
I have two 1.5TB HDs, RAID 0, as my itunes library. I use Time Machine to back up all my drive, but I also wanted to clone the RAID but only use a single drive as the clone. Will this cause any potential problems since its going from a 2 drive RAID to a single drive.
I'm still working out the details on purchasing a new MacPro. My Apple sales rep tells me that I can greatly increase the launch speed of applications and the system OS by purchasing 2 hard drives and using Disk Utility to stripe them together into a "software RAID". They claim it will be faster and more reliable than a single SSD. I know I've asked this question before, but the answers were over my head. I don't know anything about SATA raid cards, or SSD's except for their benefits. But I'm pretty sure I can stripe two drives together and make a software RAID.
I have a Lacie ext hard drive with 2 x 250gb HD that were one RAIDed into a single 500gb HD. I ran this update Lacie firmware update: http://www.lacie.com/support/drivers...r.htm?id=10053 And now my HD will only show up as two separate HDs of 250gb instead of a single RAID HD of 500gb.
how can i re-create a hidden lion partition after creating a RAID 1 array for Lion Server 10.7.3 My new mac-mini did not come in the array i'd expect it to come with being a server?
The MBP has one expresscard slot. So if you use an eSata adapter (even if it has dual eSATA ports) it would only have one eSATA channel And that would be limited further by the express card slot and more still by the type of card (make, model, etc..). My question is: with Barefeats claiming even the best eSATA card for a MBP being 200MB/s (even if you claim less) using a dual eSATA RAID connection for a stripped array would be limited to 100MB/s per port. Is this correct? Because I'm trying to understand this to see if it's worth building a RAID setup for my MBP when I'm home.
I've asked this numorous times and get helpful advice but not addressng this specific and fundamental fact. I am not interested in FW800 because I want the fastest I can get but want it to make sense. I would also reask my other questions about my situation but this question comes first.
I just order a MBP 15" i7 that i will be using for mostly Photoshop work.I was wondering if anyone had any experience with single ssd vs two at 0 raid in regards to photoshop work and or similar apps? If there is very minor speed gains for 0 raid
I have a Mac Mini that I plan to use as a simple file server with a 2TB external disk. I would like to be able to add future external disks to grow the original 2TB volume I create to 4TB, 6TB, etc. using RAID.
I know it is possible to add disks to a concatenated RAID set without destroying the data on the disks already in the set, but I cannot get Disk Utility to let me create a single-disk concatenated RAID set.
I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.
I'm a graphics professional taking the plunge into a Mac Pro. After some research, this is my notional drive setup:??GB SSD Boot Drive in the optical bay2 x 1TB 7200rpm SATA in RAID0, partitioned for 1.Data and 2.Scratch (therefore <2TB data)I obviously need to make sure that RAID0 is safely backed up. I've got an online backup service in case my house burns down and I'll be backing up individual projects onto optical media, but I will of course want to Time Machine the Data partition of the RAID.Now, for that Time machine drive I can either create another RAID0 from the same kind of drives (with the risk that entails), or for about the same money get a 2TB 5400rpm (leaving a drive bay free for future use, possibly another backup).
I have a PowerMac G3 running OS X Server 10.4.7. There is an 80GB ATA boot hard drive and a SATA card and two 250GB SATA drives. One SATA drive is existing and has data on it; I just installed the second one because I want to mirror the 1st drive onto the 2nd one.My questions are: how do I do it? When I try to create a RAID set in the Disk Utility GUI, it says all data will be destroyed. I cancelled that.So I tried diskutil enableRAID mirror disk1, which told me I could only mirror volumes.The volume name is RAID, so I tried diskutil enableRAID mirror /Volumes/RAID which gave me an error "Error enabling disk to RAID Could not unmount disk (-10000)"
Im looking into a dual or 4 bay hard drive enclosure that has the following specs i.) quiet fanii.) feature each hard drive to be seen separately as single drive, NOT as 1 big driveiii.) firewire 800
I'm having a hard time deciding what to do with my two open HDD bays in my Mac Pro.I know I want to add more storage, but I'm not sure if I should use Raid0 or not.I store most of my media on a server but wanted to store the following in my MacPro and would need more hdd space.Bootcamp - obviously can't store in serverScratch drive - would write handbrake encodes to this then transfer to serverIn all I'll need around 1.5tbI already have a 1.5tb drive and would only consider buying another to put them into raid0. Should I bother with raid0 for the increased speed or just use the 7200RPM 1.5tb drive I already have?
I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)
My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.
I have a 122x122 matrix saved as a .csv file. The values in each cell range from about -2 to +19 and I'm trying to incorporate a colors gradient were depending on the value the cell is assigned a separate color. Another option would be using a 3 column data set and attempting a listplot where the first two points plot the point an the third somehow assigns the color.
Mathematica would be ideal, since I am relatively familiar with the software, though if R is going to b easier, I'm open to exploration- I'll just need more instruction.
Edit: I think one of the Excel surface plots may also work. When I create it though, it groups all of the cell values in 3 different ranges. Is there a way for me to change this so I can have quite a few more, and preferably be able to dictate the color for each range.
2x160 GB drives in a RAID-0 holding my boot driveI want to move it do: A) Ideally 2x250 GB drives in a RAID-0 or B) A 400 GB drive.I've tried:Straight up copying/restoring in Disk Utilit Carbon Copy Cloner File-levelCarbon Copy Cloner Block-levelI can copy everything, but I wind up not having the system recognize the new drive(s) as a boot drive.
I recently bought a Lacie 2big Raid drive with 2 x 1 TB drives for backup of my images (I'm a photographer).
Everything was fine, mounted the drive, formatted, and used SilverKeeper to transfer all my previous work onto the drive which was formatted with RAID 1 (mirrored).
The files all seemed to transfer across fine, size was the same, and I had a quick flick through the drive and images where all ok. So needing to use the drive that these images CAME off, I formatted that, and put that to use where it was needed.
So in summary I had the Lacie RAID 1 as my 2 sources of backup at this point. I thought everything was fine at this point.
Now maybe a few months on when I have to track back for files, I noticed quite a few folders had been corrupted, for example, opening a job folder, and every type of image file, jpeg's, tiffs, and PSD's would all say they are corrupt when I tried to open them in Photoshop. Some of these jobs where 20GB of RAW and edited images, all corrupt.
So, reading through my manual for the Lacie, it said I could remove the 2nd drive, without altering the 1st drives data.
With this I removed the second drive, trying to narrow out any problems with the RAID. Mounted the disc, same corrupt files.
I then replaced the second drive back to the RAID, which the instructions said was fine, and it would just rebuilt the mirror, so I left if for a few hours while it rebuilt the second drive.
Now my problem, the RAID has finished mirroring the drives, and now my MacPro or Powerbook won't let me mount the drive without formatting it which I obviously can't do, It brings up Disk Utility when the drive is switched on and wants me to format the drive to mount it.
I have a 250GB firewire drive. I have a G5 iMac and an Intel iMac. I'd like to make bootable clones (about 60GB each) of each for off site backup, so two logical partitions. As far as I can see, the partition table scheme is determined at the physical drive level. But I need the logical drives to be Apple for the G5 partition and GUID for the Intel partition (please correct me if I am wrong) in order for them to be bootable. Is there any way around this, or do I need two physical drives after all?
I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.
