Mac Pro :: Making 4 Disks Into Raid 5 Array Setup?
Jan 9, 2011
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.
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?
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"
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.
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.
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.
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.
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.
My brother is going to start school in June for Film. He is all set to buy a Mac and knows the software side of things but not so much the Hardware side.
I have a few questions:
1. Should extra hard drives be bought third party?
2. Should he do a raid setup for backups?
3. How much memory should he buy for Final Cut operations? (third party)
4. Should he look into getting a Dell monitor instead of Apple? What is a comparable Dell monitor?
So, please welcome me back. After 15 years (I had Mac Plus, LC and Quadra 650), I am back from the darkside. Bought myself a Mac Pro today. Yeah - I probably should have waited for nehalem, but my PC was getting flaky. Time for the every 9 month wipe/reload and I just didn't want to go through that again, so I jumped. Tomorrow I am moving drives into the MP. My questions is specifically about partitioning and Raid. I typically partition my drives about 1/2 way down the middle and give the 1st partition to high performance needs and leave the second for infrequent use of backups and storage.
Lets assume I have two WD6400AAKS (I have three actually). Ideally, I'd like to partition them like this: WD1 Partition 1A (200GB) Partition 1B (400GB) WD2 Partition 2A (200GB) Partition 2B (400GB)
Then (using Soft Raid) - Config partition 1A and 2A as Raid 0 Striped (giving me 400GB high performance) - And config partition 1B and 2B as Raid 1 Mirrored (giving me 400GB redundant backup)
(Yes - of course I don't want to access the mirrored drives when expecting high performance from the striped drives). I assume that once the drives are partitioned, the Soft Raid will simply see them as four different drives allowing me to configure them as described. But before dropping a few hours into this, I thought I'd let all you raid/hard drive experts give your opinion.
I have a hex with 4x 2tb istalled on regular Mac bays and one ssd on the optical bay. They(4x 2tb) are configured as a giant 8tb JBOD. Now I purchased 3x 3tb and a sata card for the extra sata ports. Is there a way to create another JBOD with the the new 3tb drives and in the near future get rid of 2tb ones and put the 3x 3tbs on the regular Mac ports without loosing the data. All JBOD will be and was created using Snow Leopard's disk utility.
I inserted 4 new 3TB disks into the bays of my Mac Pro (2012), and there is no RAID option for them.
How I got here:
Inserted the WD Red drives, and they were not initiated.
I "erased" the drives, gave them names, and they appear in Disk Utility in grey drives.
Went to set up the RAID, and move the drives into the RAID, but got an error that they could not be used.
It appears to me that disk utility is not allowing me to fully use those drives. I Have created RAID drives before with no issue in RAID1 with 3TB drives before on this machine. Am perplexed, I thought this to be the easy and simple part of my upgrade odyssey! Did I screw up the initialization? On all FOUR drives?
Now, if I click on the drives, the RAID option does not present itself.
FWIW, I am using OS X 10.9.5, on Mac Pro 5,1. I boot from PCIe card. My end goal is to create a 4-disk RAID 10 using the four SATA connections on the MP.
I own a PowerMac G3 with 2 hard drive disks. One is a 20gb and the other is a 40gb. I would like to combine the disks with a pseudoRAID type called JBOD. JBOD stands for 'just a bunch of disks.' It's not really RAID. What I'm after is to see these two drives as one 60gb drive. Is that possible? I'm running Mac OS X Tiger.
Can I just remove one of the drives and what are the consequences of the removal. I would like to go from a mirrored raid to a carbon copy of the disk which would be updated weekly and use Time Machine in between.
Do I open up a can of worms - my suspicion is that if I want to do that I'll have to reformat the RAID with the loss of all data.
Any workaround short of making a copy, removing the raid and restoring the data?
I'm about to get a Mac Mini Server for audio, video, and graphic production, in addition to everyday productivity use. If in the same situation, which would you prefer?
1) to stripe (Raid 0) the two internal disks, or
2) use one as the install/OS disk and the other as the data/scratch disk?
(...assuming you have a 1TB external backup drive, and find FW800 to be much slower than internal SATA for a data/scratch disk).
I have an old iMac g3 w/ a 266 MHz PowerPC processor, 160MB of RAM, and a 6GB Harddrive. It is running OS X 10.2.8. I need to get rid of it, but I want to make sure it is cleared of all my data first. Maintaining functionality would be nice so that I can try to sell it. My problem is that I don't have the original install disks. How can I can wipe the memory from my iMac and restore it to a usable condition w/o the install disks.
I realise this topic has been discussed a lot so I apologise if this new thread is a repeat of another - I searched for the question I want to ask but couldn't find anything. Basically, I'm confused about the zeroing out data process. I need to be certain that it's impossible to tell if internet pages of a particular nature have been viewed on this macbook. I was feeling paranoid so I ran a 7 pass overwrite. However my CD drive doesn't work so I was unable to do anything with the grey setup CDs. Nothing seems to be particularly different following the overwrite - the files on my desktop had been deleted but that was all I could notice (I am a beginner mac user though). So now I'm not sure where I'm at. Would the 7 pass have overwritten all the sensitive info I wish to make unrecoverable, even without using the setup CDs?
I have 2 1TB drives coming in on Monday, and I plan to put them in a mirror RAID using Disk Utility. How reliable is the OS X software RAID setup? Would I be better to just manually backup from one drive to another? The drives will be for my photography, I wanted a mirror setup so I'd finally have a backup of my (current) 250GB's of photos. (Most of which I could probably burn to DVD's but humor me.)
If the RAID crashed somehow via the software, would the data still be recoverable? I have a MP and will be putting them in Bays 3 & 4. Also, is there any benefit to the different block sizes? Since my files will all be at least 7MB would the biggest block size speed it up?
I just got a brand new MAC PRO desktop. It came with a 600GB HDD. I purchased a second identical internal 600GB HDD. I wanted to do setup a RAID 1 using these 2 drives. Currently the main drive has the OS and all my other apps installed. I installed the 2nd drive and was fooling with disk utility. I'm not sure how to set this up however. I tried numerous guides online but I just cant figure it out.
MAC PRO (takes up to 4 internal drives) - currently installed 2 identical drives Leopard Using Disk utility
The RAID tab says "online" and the status is green (indicating the RAID is working). However on my desktop i see the 2nd hardddrive mounted with no contents in it. I just want to able to use the 2nd drive as a mirror so this way if one fails I'm still up and running.
I'm planning to setup a RAID on My Mac Pro (2006 2.66 Quad Core). I know Bootcamp not support Hardware Raid Card. Can I use the Hardware Raid Card for boot Mac OS X and storage Data, and use the onboard controller boot the Bootcamp Drive?
this is what im currently goin with.. SSD as boot/apps and a 1TB for data.. but a couple people suggest 1TB drives in raid.. 1. what do I need for raid? 2. how does it compare against the SSD+1TB setup? 3. can I add raid to the SSD+1TB and get more 1TB drives later?
Basically this would create a big 4 gig array that I could split into multiple partitions. I'd have mirroring and fast performance. I was wondering what the performance difference would be between the Greens and Blacks - Greens are known for worse performance, but I was wondering if in RAID 10 it would even matter.
I have a PowerMac G4 I'd like to use as an "experimental" backup machine. I am looking to try and make a RAID setup in it, and I'm no expert with that. I'm wondering if this is even possible, first. I'm also wondering if I can do this with 2 40 gb drives and a 20 gb drive. I want to make it so it appears as 1 drive. I'd be using tiger and a software RAID if that is of any relevance.
Specs: 500 MHz PowerPC G4 640 MB SDRAM No hard drives currently
Setting up raid 0 for my mac pro 3,1. Right now I have the stock 320GB drive that I use with Mac OS X, and an additional 500GB drive running Win XP through Bootcamp. I read on apple's site that you could stripe multiple drives to create a raid 0 to increase performance on the Mac Pro w/o the raid controller card. So my question is how do I do that? I'm in the process of picking a new 2TB drive to set up the raid with the 320GB OS drive. Since the 500GB one is dedicated for XP I don't think I could include it in the raid right?
I bought this Hard drive under the impression that its going to be easy install. I went through the manual steps to install all went ok to last step which is partition and format using Disk Utility. now i dont know what to do, is the hard drive going to do the Raiding, or I have to setup using Raid tap in Disk Utility? I tried doing Raiding using Disk Utility but couldnt do it, i thought maybe i cant because its hardware raid or i searched until my head exploded, and I feel its easy but i am not getting something tiny here.
I plan on using a set of 5 [2TB] drives in a RAID setup. Looks like WD is the manufacturer but I'm not really seeing a lot of input online for these other than that they have been recertified
I have two questions. Firstly, I am considering buying a western digital MyBook Studio Edition II [URL]. If I use time machine with this drive, will I be able to remove one of the drives and keep it off-site for safekeeping and have time machine continue to backup on the remaining one as usual? Secondly, if I remove drive #2 and keep it off site, would dropping it back into the raid setup update drive #2 with drive #1's current time machine backup? I'm new to raid, and I am basically trying to have a time machine backup, and a off site backup.
In my Mac Pro I currently have the stock HD as my OS/Home drive, while the other two 1TB WD Black drives are RAID 0 partitioned into a 1.5 TB Data drive and 256GB Scratch. I have these and my OS/home drive backing up to time machine but when I eventually upgrade to 10.6 (and probably clean install) will I lose my RAID setup and have to re-create it byte-by-byte in order to restore from my Time Machine backup? Or would I have to do the 'upgrade' installation to get around this since I used Disc Utility to create my RAID setup?
