Upgrade from iMac to Mac Pro - RAID5 options?

I am currently using a 27" iMac 2.66 Ghz Core i5 for my main processing needs (RAW image file editing in Adobe Lightroom & Photoshop plus HDSLR footage editing in Final Cut) and am feeling constrained by my storage options (I don't like external enclosures but want a separate boot/apps drive from my media drive) so my only logical upgrade path is a Mac Pro.
My ideal solution would be to have a lightning fast boot/apps drive (SSD seems obvious choice) and then a RAID5 array of 3 large (2TB) drives to give me at least 4GB of media storage.
The problem is that when I go to spec a Mac Pro with a hardware RAID card (because I understand that software RAID under Disk Utility can only offer RAID0 or RAID1), I am told by the web configuration tool: "Solid-state drives are not compatible with the Mac Pro RAID Card in either RAID or Enhanced JBOD mode."
What I would like to know is whether this is an absolute technical limitation or is it just something that Apple does not officially support? This would be my main production machine so I don't want to implement any hacks.
P.S. reason for my current dislike of enclosures is the extra cables/space/noise/heat they generate and also the current debate over interfaces (would like to use eSATA or USB3 to get fastest transfer speeds).
Thanks in advance for any replies!

3 drives to me = RAID3
Apple Pro RAID card: find a good external - threads discussing options - look at AMUG reviews and elsewhere. CalDigit or something. Maybe RAID6 capability.
I would use internal drives in software RAID0.
And the only interface for external, SATA only cases, none of these consumer cases for multi interface, though OWC has a popular RAID5 4 drive setup you might like.
Use OWC SSD or two for system, and 3 x 2TB WD Black RAID0. No trouble with that. Just lots and lots of clones and backups is all.

From iMac to Mac Pro for the good of my Pro Tools 10...

hey guys,
here's the deal : it seems I'm at a turning point with my iMac (27", 3.1 Ghz i5, 4GB memory, 1TB hard drive, lion, PT10) and I'm thinking of buying a mac pro. Problem is, I'm not sure which model is best for my needs. I do postproduction work for television and I often have to work with pretty heavy projects.
My pro tools 10 keeps giving me the same 2 errors --
1- DAE can't get audio from the drive(s) fast enough. Your drive may be too slow, or fragmented, or a firewire drive could be having trouble due to the extra firewire bandwidth or cpu load. (-9073)
2- A CPU overload error occurred. If this happens often, try increasing the "H/W Buffer Size" in the Playback Engine Dialog, or removing some plug-ins. (-6101)
I might add, my Playback Engine's maxed out and I'm barely running any plugins (some 5 or 6 EQ3s, maybe 1 or 2 L2 and a Dorrough).
I have a MOTU Audio Express which is plugged in firewire and I'm running an external drive with my SFX on it, which is also plugged in firewire. The iMac having only one firewire plug (downsizing from the earlier iMac, for some obscure reason), I have a firewire hub.
I get the first error whenever I get too deep into a project and I start having a lot of SFX and I'm looking to add more and I get the second error whenever I try to run Dolby Media Meter.
I'm pretty aware I'm overrunning my iMac, so I'm willing to pay big bucks to get a computer that's best fitted to my needs and which I'll be able to upgrade every once in a while. Now, I'm just wondering what I actually need in a computer.
It's either the 3.2 GHz quad-core intel xeon, 6GB memory, 1TB HD or the two 2.4GHz 6-core intel zeon, 12GB memory, 1TB HD. I gotta say the second one seems kind of a lot... but I don't want to spend so much money and get a tiny upgrade from where I'm at right now.
So please! All of you mac wizards and other knowledgeable folks, HELP!

An i7 3.9GHz would do if you had 32GB RAM, an SSD boot drive, and 2TB hdd.
The sweet spot today on Mac Pro is $1800 4-core special and DIY to W3690 or W3680 6-core 3.33 or higher with 32-48GB RAM. And lots of SSDs and disk drives.

The Mac Pro line is at a - not ready to ship the new 2013 6,1 model / not ready with 10.9 that it will need / and current configuration is really 2010 3 yrs old (but also how well they hold up and mature).
You do not want to give up GHz for more cores. MHz still rules. Only reason would be if you planned to replace the processors for the fastest expensive (use to be, though changing) 4 or 6-core 3.4GHz for total of 8 or 12-cores, but never the 2.4GHz, no way.
The 2009 4,1 used is cheaper and can be found for $1000 and upgraded to 6-core and everything else (dual core upgrades are harder and not good to plan for.

From iMac to Mac Pro for video work.. suggestions please!

Hello all! Soon I'll be upgrading from my 2.66 GHz quad core iMac with 4gb of RAM to a new Mac Pro. The idea is to increase my productivity with applications such as After Effects & Final Cut Pro by hopefully decreasing time spent rendering/buffering/burning. The iMac has been working really well all this time, but a bit faster would be better!
I have about $4,000 to work with for a new machine. I welcome your thoughts on the best bang for my buck, be that a new/refurbished from Apple or used from eBay. Thanks everyone!

The Hatter has provided his insights as well as some excellent links.
The performance of the 2009 and later models is nearly twice that of the previous models with the same specs due to architectural changes including Hyper Threading.
All the Xeon Macs are keeping their value very well, and that means there are very few real deals on eBay.

Upgrade from G5 to Mac Pro--no apple TV

I had all my data transfered at the apple store, but no devices in itunes. I have 2 apple TV's which have been upgraded to 2.0 and they were working fine before. I can't find a place in apple TV 2.0 to resync. How do I get my new Mac Pro to recognize my 2.0 apple TV's?
Thanks

remove the itunes library on the appletv (settings>computers).
then you need to add a new library.

IMac or Mac Pro for iPhoto albums and home movie editing?

I have a Mac Pro OS X 10.6.8 with iPhoto 7.1.5. This system is now obsolete for ordering iPhoto albums. I need to upgrade to iPhoto 9.5.1 to buy a Mac produced photo album. To upgrade iPhoto I need to buy a new Mac as my 2004 Mac Pro with 2008 Snow Leopard can't be upgraded. I will use the new Mac for email, web surfing, iPhoto, and weekend video editing. I use Final Cut Express on my current Mac Pro. I will also need to transfer videos and about 20,000 photos from my current Mac to a new one.
So, here's the question: For my needs (listed above) which is better,
(1) iMac 27" or (2) new Mac Pro? Then, with the one chosen, how should it be configured to do my basic video editing? I have 100 hours of family video on Hi8 and VCR tapes and will edit these on Final Cut and burn them to DVD's. (I understand both iMac or Mac Pro now require an external DVD set-up.) So, which computer and how should it be configured. Looking to pay between $2500-$3500. Thanks for your help!

What video formats are you talking about? DV, HDV, etc?
Mac Pro is a better solution, regardless. Here's why: Simply upgrading an iMac HD is not enough. You do not want to capture your video to the boot drive. It's too much to ask the drive to manage the OS, your editing software, AND your media. This scenario might work - but is certainly prone to dropping frames. Ideally, you want one drive for OS + editing software & a separate drive to capture media to.
Now, since you can only have a single HD in the iMac, you're demoted to using external capture drives. So let's say you get yourself a FW800 drive for capture and then hook up your camera/deck to an available FW400 port. You'd think you're safe - and again, you may be. But the problem now is that the iMac has ONE and only ONE FireWire bus. So in theory these 2 devices: HD & Camera are battling for the same bandwidth. So you've still got a bottleneck happening.
So DV only would probably work. But it may have issues that the expandability of the Mac Pro can conquer. Hope this helps.

HT1338 Can I upgrade my Intel Xeon MAC PRO running OS X 10.4.11 to 10.5.8?

Can I upgrade my Intel Xeon MAC PRO running OS X 10.4.11 to 10.5.8?

Yes. You can actually upgrade it all the way to Lion should you so wish, although you would need to first purchase and install Snow Leopard 10.6.8.
I would skip Leopard as it's more expensive and obsolete. You can purchase a Snow Leopard DVD at any Apple retailer - $29.00. You can update it by downloading Mac OS X 10.6.8 Update Combo v1.1. The use the App Store to purchase and download Lion should you choose to do so - $30.00.
I would consider expanding your RAM to at least 4 GBs or more especially if you decide to upgrade to Lion. Before upgrading see the following:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

SADLY not as i downloaded an upgrad to my original PAGES/
i have in the meantim had to open www.icloud. then from there import the file that i am working on and then check on ipad if it uploaded/ yes it did.
but what a waste of time as it doesn not save any changes done automatically back in the cloud....
i am now downloading the new LION and hope that it will fix the problem
i cant find any other way. I was lead to believe that you wrote, it saved automatically, on to the cloud, you then opened anohter device in anotother country even, and the new file was there, waiting, in its latest version.......
and the same magic was supposed to happen in reverse.
It doesn't/
if i have to open a browser, go to www.icloud....why on earth did they not just leave us an icon to drop it in in that case?
I hope the new lion will help resolve the isssue/
any other ideas> keep em coming...thank you so much.

IMac vs Mac Pro

I am stuck on a decision for which computer is best for me. I am a camera operator and filmmaker. I use my mac very strenuously dealing with 4k raw footage. I am running programs live Avid Davinci Resolve and AE so having a good computer is important and not breaking the bank is also important.
Right now I am running a Mac Pro 3,1. Shes on her death bed but was curious if I could upgrade her to meet 4k standards. So my first question is what can I do to make this machine usable for 4K video editing? Give me a list of products I could put into her to make her a beast again.
My other option is to upgrade to a maxed out iMac 27inch. I like this option because of the design and all in one is nice for my desk but Im not sure if the longevity of this device is good and if she can handle 4K very well.
My last option is a base line 2013 Mac Pro. I dont know much if anything on this mac.
So what would you pick? I would love a list of upgrade parts for my Mac Pro 3,1 so I can get an estimate on how much that would cost.
Thanks Guys

I feel that an iMac with the newer Pegasus thunderbolt RAID enclosure will do exactly what you want.
What you need is a fast data storage system and not much else for 4K editing.
And even if it's not Pegasus you will get some sort of RAID for the Mac Pro since there are zero options to expand the internal drive to something that will suit your needs.
Yes the iMac won't have the dual graphic cards the Mac Pro has but my guess is you won't really need them.
So instead of investing money on the Mac Pro I would spend that difference on a good RAID system.
I would even say it might be worth a look to see if you can find a way to fit your current MacPro with a really fast RAID system.
There are options to also upgrade the graphics card for your machine and also your CPU.
The old Mac Pros are really capable machines so try also to see what you can do with it.
I regret selling my 2006 MacPro and I had fewer upgrade options than you have.
With 300euro I could upgrade the CPU to the exact same render speed of the late 2012 iMac I have at the moment.
So check all the different options and see what makes sense for your needs.

After upgrading to Mavericks my Mac Pro does not open my double CD drives when I hit eject in the menu bar it locks up (please Help)?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Imac vs mac pro for FCP?

Hello folks,
Well, my G5 apparently needs a new logic board. I could cry, or be happy at the excuse to get a new computer... I chose the latter!
Bottom line, what is the consensus regarding imac vs mac pro.
I will be using FCP a lot, that's what I do for a living. However, I rarely run other applications at the same time. Occassionally LiveType or Photoshop, but that's about it. No Motion, no After Effects, etc.
I feel that an imac will suffice nicely and that the mac pro is overkill in both cost and amount of computer. It's like getting an Indy car and driving 40 MPH!
Thoughts? Thank you.
Eric P

hmmm, interesting. Of course the mac pro would be better, no doubt. But for my purposes I still wonder if it's worth the cost.
As for Kevan D's inquirey for more info, yes I work with FCP for a living, at least 50% of my work week maybe more is editing. However, silly little ol' weddings have become the vast majority of my work and they will continue to be for at least a few more years I believe. In that time I do not see HD being a factor in my area. So for the forseeable future I expect to be working soley with SD. That bit of info may change some of your minds to thinking that an imac will suffice.
I admit, that's my hope because I would have to take out a loan for the mac pro, and again, I'm just not certain it's worth it for my purposes. On the other hand, I didn't ask the question so that I could hear what I "wanted", I do want honest opinions from other professionals like yourselves. If the experience is that an imac just isn't worth it then so be it.
As far as expandability (is that anything like drinkability??), I understand that, but again for my purposes I suspect that by the time I need to expand to HD or to using the full benefits of a mac pro, a new computer (and equipment) will be in the order anyway. Does that make sense?
Thanks again,
Eric

Advice on upgrading to SSD for Mac Pro (optimized for AfterEffects & Photoshop)

Hello,
I'm an animator (I use AfterEffects CS5, but will be upgrading to CC soon) and I'm going to start work on a new AE project in a few months for an animated film that will be very demanding (lots of different shots -- meaning multiple projects, all of which will also incorporate large HD stock footage elements as well as multiple layers of art created in Photoshop).
So I'm looking to upgrade my current desktop Mac Pro (a 2010 2x2.66GHz 6-Core Intel Xeon) with SSD drives (and possibly a new graphics card) in order to speed up my system and optimize it for both AfterEffects and Photoshop. (In the past I've created projects using external 7200 RPM hard drives connected via eSATA). I've also decided, for now, not to purchase the new Mac Pro, but rather try and make a smaller investment to speed up my current system.
I'd love any advice that pro users would have that have made similiar upgrades, both in terms of the best equipment (SSD drives and graphics card) and the best way to set up AfterEffects/Photoshop projects using these SSDs.
For example:
1. Should I be purchasing 1 or 2 SSDs, and how should I be using these drives to optimize my system for AfterEffects and Photoshop?
2. Should I install my operating system (I'm on OS 10.8.5 but plan to upgrade to Mavericks when I upgrade to CC) on one separate SSD, and then install my Adobe applications on a 2nd SSD, or can I put both the operating system and applications on a single SSD? And should I be saving my projects on a SSD (if so, which one, if I'm supposed to purchase 2?
3. Should I assign a 2nd SSD as a scratch disk for AfterEffects or Photoshop?
4. I plan on using my current external hard drives (a 12 TB RAID array connected via eSATA) to store the footage and Photoshop elements being used in my AE projects (these files will be multiple GBs, and I can't afford to purchase SSD drives to hold these elements on) and also to store the renders from AfterEffects (which will also be very large files). Is this OK, or will this slow me down and negate whatever speed I've gained from moving to SSDs?
5. In researching how to switch over to SSD, I've considered purchasing 1 or 2 SSD drives. The one I'm currently looking at is called the Murcury Accelsior_E2, a PCI Express SSD sold via OWC. It comes in a few different sizes (120 GBs, 240 GBs, 480 GBs, 960 GBs). Just wondering if this is a good purchase -- the reviews seem to be very positive:
http://eshop.macsales.com/item/OWC/SSDPHWE2R960/
6. I'm also considering upgrading my current graphics card (ATI Radeon HD 5870) to the NVIDIA Quatro 4000 or NVIDIA Quatro 5000, but I'm wondering how much of a speed boost this would give me.
Here's an overview of my current system:
Computer: 2010 Mac Pro with 2x 2.66 GHz 6-Core Intel Xeon
Memory: 64 GB DDR3 ECC
Graphics Card: ATI Radeon HD 5870
Hard Drives (Internal): 2x 2TB Hitachi HD
Hard Drives (External): 12TB OWC Mercury Elite Pro RAID drive array (connected via eSATA)
Apologies in advance for the long message, but I've always recieved great advice from these message boards and I'd appreciate any help!
Thanks,
Dan

Thanks so much for jumping back into the discussion, The hatter! I had some earlier questions from before that I was hoping you could answer:
Currently I own a 12 TB OWC Mercury Elite Pro RAID drive array (connected via eSATA) which I use to save projects, project files, and renders. So (unless I am mistaken) you're recommending that I continue to use this RAID array to save projects, project files, and renders.
(I was looking into purchasing a Mercury Accelsior_E2 for my SSD via PCI -- it has eSATA, so I can continue to connect my RAID array)
Then I would use my new SSD via SATA II for my system, apps, and OS (minus home folder media files, data, documents) and my SSD via PCI for scratch disks for Photoshop/AfterEffects.
Currently I have 2 x 2 TB internal hard drives, which have all my OS + home folder media files.
Can I get more details in terms of the step-by-step instructions when it's time to install/clone? Here's how it looks to me (apologies if I have this out-of-order, and feel free to correct me if I've missed a step or have it wrong -- thank you in advance!):
1. Purchase SSDs (via PCI and internal SATA II) and install them inside my Mac Pro.
(Is there any formatting I need to do at this point to the SSDs once they are all plugged in...?)
2. Install TRIM Enabler
(Once it's installed, what do I do with TRIM Enabler? Is it an app that runs 24/7 in the background, or is it an app that I need to launch on a regular basis and perform commands on the SSDs...? Very confused on what TRIM Enabler does.)
3. Use CCC to clone system from old internal hard drive to new internal SSD drive. When using CCC, deselect media folders in home account before cloning (so I am NOT cloning media folders from old hard drive to new SSD drive).
(What specific media folders should I be deselecting? I'd like to keep my music, movies, iPhoto/Lightroom files, and email archive where they are now -- on the 2 x 2TB internal drives that shipped with my Mac Pro. Is there a link that provides more info on this process? Never used CCC before but I assume it's not too hard to use...?)
4. CCC clones system gets 'cloned' (minus the media folders) to the SSD that is installed via SATA II in empty internal drive bay inside Mac Pro.
5. Repair the SSD with DU after cloning and before using and booting from SSD.
(What is DU? How does it work? Not familiar with DU...?)
6. Reboot computer from system running on SSD.
7. Open Photoshop/AfterEffects (now running from SSD) and assign new scratch disk (the SSDs on PCIe SSD controller).
8. After 100% sure that system + apps that have been cloned is working via SSD, delete ONLY system and apps from old hard drive (but do not delete media files).
(Now that my system is on a separate SSD drive, when I do things like purchase new music from iTunes, will it get downloaded to the old location (my old hard drive with all my media)? In other words, are there steps I have to perform in order to relink my media folders now that they're on a separate drive?
Thanks,
Dan

HT3231 Can i migrate keynotes from iMac to Macbook Pro?

Can I migrate Keynotes from iMac to Macbook Pro?

Do you mean the program itself? If so then if it was bought from the Mac App Store just logon to the MAS with the same Apple ID you used when you bought it and redownload and install on the new Mac.
If it was bought on DVD then get that DVD out and install in on the new Mac then run Software Update to bring it up to its most current version.
If you mean the Keynotes you created then just copy them over your LAN from one Mac to the other.

Imac verses mac pro - for Adobe Creative suite

Reguesting input: Which is better for operating Adobe Creative Suite 6.0 on a professional level, imac or Mac pro?

The raw compute power of today's iMac is more that the reasonably-priced Mac Pro models. But that is not the complete story.
The Mac Pro has:
• replaceable graphics cards and additional PCIe slots
• Error-Correcting Code memory, large memory sizes are attainable and will not be a headache.
• Four internal drive bays as opposed to one internal laptop bay. (except, the Fusion drive option in the iMac is fast and large-capacity)
