What RAID Setup do you use for your Macbook Pro Scratch Drive?

Is there any benefit to using an Express-ESata Raid Enclosure vs a single esata drive as the scratch drive?
If so, is there any benefit to using a 4 drive Raid 0 vs a 2 drive raid 0?
What Raid setups are any of you all using with your MacBook Pro's? Is there a significant performance difference between using a E-Sata drive and a FW800 drive. Is RAID the right way to go?
Sorry I'm not making a lot of sense right now, but I've searched through 20 or so pages of the forum and didn't see that anyone had addressed this question yet.

OK, just to give you a frame of reference, I just performed the following tests -
I hooked up my Sony AVCHD camera to my Mac Book Pro 2.4 ghz with 4 GB ram - (pretty close configuration to yours) - and imported a 26 second clip into FCP 7 with the following drive configurations:
Capture to internal Mac Drive, no externals: 26 Second clip takes 44 seconds
Capture to external WD USB2 drive: 26 Second clip takes 44 Seconds
Capture to external CalDigit 2 Sata Drive Array, Raid 0, via Firewire 800: 26 Second clip takes 42 seconds
OK, so now I move the camera over to my Mac Pro 8-Core, 2 x 3.2 Ghz Quad Core Xeon with 14 gigs of ram, and capture *to the same external CalDigit 2 Sata Drive Array,* Raid 0, via Firewire 800: 26 Second clip takes 11 seconds
My conclusion would be the drives and drive throughput is not as consequential as the CPU horsepower in doing the conversion from AVCHD to Pro Res. However, there are many very knowledgeable people who look at these threads, and I would be interested to hear what they have to say.
Hope this helps.

  • Which sleeve/bag/case do you use for your Macbook Pro?

    So what do you use? I've been stumbling across ebay to find something decent for my 15 inch mid 2009 but most of the sleeves don't fit the new macbooks...

    for my 17" MBP I use a Waterfield bag (http://sfbags.com). It's actually a sleeve and a cargo bag combo with a nice cable bag as well. Not cheap ($270 or so), but it's very well made and a very nice compliment to the apple in terms of fit, finish, and quality. The Waterfield bags are fantastic, and the sleevecases are very protective, such that you could buy just the sleevecase and drop your computer in whatever bag you like at the moment.
    For an older 13" white macbook, I have a Pinder thin, which is much cheaper (~$35 on sale) and is a nice thin minimalist bag. It makes for the smallest laptop and bag combo I've seen (prior to the air) that I would be comfortable carrying around.

  • What Monitor Do You Use With Your Macbook Pro

    I was looking into purchasing a new monitor for my Macbook Pro. It is an older one, 15" 2.5 GHz. I was going to bite the bullet and get the Apple 24" LED one knowing it is a great monitor overlooking that price is almost double of other monitors. But looking at the compatibility, I have to get a $150 adapter which I think puts me over the price hit.
    Just wondering what monitor/displays is everyone using that don't require a $150 adapter?

    Go to Apple menu -> About This Mac -> More info and tell us your Machine ID.  This will say MacBook Pro x,y.  It is those x,y values we need to know.

  • What kind of cd/dvd cleaner can I use for my Macbook Pro optical drive

    Can I buy any kind of cd/dvd cleaner at like best buy, or is there a specialized cleaner made only for Mac drives?
    I (like most people) have been having problems with my drive and thought cleaning it might solve the issue.
    Thanks.

    I have had issues for months with my MBP not reading some dual-layer DVDs.
    After much trepidation I just used a cleaning disc I bought from the supermarket.
    Lo and behold! My Mac now reads discs that it would previously spit out or register as blank.

  • Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    I agree - it's all about preference.  I use the ThinkTank Retrospective 7.  I *love* ThinkTank's attention to detail...  everything from having a rain cover included with the bag, to having ingenius use of velcro (sp?) patches to enable you to "silence" the bag so it doesn't make the big "SCRATCH" sound when opening the bag during a quiet event, etc.
    My best advice would be to do your research (which you're clearly doing) and have a clear understanding of the return policy wherever you buy it, and then don't be afraid to return it if you get it and feel it doesn't meet your needs.  A restocking fee is a small price to pay to not be stuck with a bag that doesn't work for you.  And if for any reason you get it and can't return it, there's always eBay. 

  • Which CPU Cooler did you use for your CPU?

    Hi guys, just wondering, what CPU Cooler did you use in your mega 865?
    Did you use the Intel or the MSI CPU cooler?
    Which do you think is better?
    I used the MSI CPU Cooler, Which I think is better cause it has a copper base which can transfer heat faster. Also the heatsink must have been designed for the case too.

    ^
    The Mega 865 came with an additional "extra page" on how to install the Intel CPU Heat Sink into the 865, so it could be that msi thought that intel's solution was better? The manual of course had how to install the msi heat sink, so rather than printing the manual again, they provided an extra information sheet.

    I am using ERwin® Data Modeler r7.1 (7.1.1.1207). It supports most new features of Oracle 10g such as hash, list, composite hash, setting LOB storage properties etc.
    We just upgraded from version 4 recently. In the old version, I had to manually modify the generated scripts.
    ERWin r7 supports all Oracle 10g (Release 2) new features we need for our projects. It offers far more functionality and options than the old version. It supports all partition types in Oracle 10g: Range, Hash, List, Composite-Hash and Composite-LIST and offers more storage settings.
    Another nice new feature of ERWin r7 is that it offers purge option in the DROP TABLE statement. In Oracle 10g, the recycle bin contains all the dropped database objects until you permanently drop them with the PURGE option. Otherwise, you will see many funny looking objects like this: 'BIN$0+ktoVChEmXgNAAADiUEHQ==$0'.
    With the purge option, you don't need to purge the recycle bin after the forward engineering.

  • What antivirus protection should I purchase for my MacBook Pro? MacSecurity.app appeared on my desktop, and I downloaded that. Since then, it has said my computer is infected and pop-ups have been appearing.

    What antivirus protection should I purchase for my MacBook Pro? MacSecurity.app appeared on my desktop, and I downloaded that. Since then, it has said my computer is infected and pop-ups have been appearing.

    You've been infected by a scam trojan.  You don't need any anti-virus software on your Mac.  See the following about getting rid of the trojan.
    Trojan War
    If you discover a trojan program is running on your computer then look to the following information for assistance:
    1. A recent discussion on the Apple Support Communities: MacDefender Trojan.
    2. An excellent site devoted to Mac Malware: Macintosh Virus Guide
    3. Another site for removing MacDefende, et.al.: MAC Defender Rogue Anti-Virus analysis and Removal
    4. A new removal utility - MacDefenderKiller
    Removing strange software can be a task.  The following outlines various ways of uninstalling software:
    Uninstalling Software: The Basics
    Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash.  Applications may create preference files that are stored in the /Home/Library/Preferences/ folder.  Although they do nothing once you delete the associated application, they do take up some disk space.  If you want you can look for them in the above location and delete them, too.
    Some applications may install an uninstaller program that can be used to remove the application.  In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
    Some applications may install components in the /Home/Library/Applications Support/ folder.  You can also check there to see if the application has created a folder.  You can also delete the folder that's in the Applications Support folder.  Again, they don't do anything but take up disk space once the application is trashed.
    Some applications may install a Startup item or a Log In item.  Startup items are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder.  Log In Items are set in the Accounts preferences.  Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab.  Locate the item in the list for the application you want to remove and click on the Delete [-] button to delete it from the list.
    Some software use startup daemons or agents that are a new feature of the OS.  Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
    If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term.  Unfortunately Spotlight will not look in certain folders by default.  You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead.  Download Easy Find at VersionTracker or MacUpdate.
    Some applications install a receipt in the /Library/Receipts/ folder.  Usually with the same name as the program or the developer.  The item generally has a ".pkg" extension.  Be sure you also delete this item as some programs use it to determine if it's already installed.
    There are many utilities that can uninstall applications.  Note that you must have this software installed before you install software you may need to uninstall.  Uninstallers won't work if you install them after the fact.  Here is a selection:
    AppZapper
    Automaton
    Hazel
    CleanApp
    Yank
    SuperPop
    Uninstaller
    Spring Cleaning
    Look for them and others at VersionTracker or MacUpdate.
    For more information visit The XLab FAQs and read the FAQs on removing software and dealing with spyware and malware.
    After removing all the components of the software you may have to restart the computer to fully disable the software.  This will be the case when removing software that has installed a daemon.  After the daemon has been removed you need to restart the computer to stop the daemon.  Alternatively, you can kill the daemon process using the Terminal application or Activity Monitor.

    What is the best antivirus software for a Macbook Pro...I recently received a message from Google that someone made an attempt to hack into my mail account and I needed to change my PW and verify myself as the user.  The message suggested that I run a virus scan to check for sny malware or other types of viruses.  I do not have any software for this and up until now have not had a problem....any help is appreciated.  I would like a simple but effective solution!

    It's worth noting that if your Gmail has been hacked, it would likely have nothing to do with your MacBook.  Hacking web based email is fairly common and it doesn't require any access to your machine whatsoever.  In the same way that you can simply go to the Gmail webpage through any browser, any hacker can use the same method.  It doesn't mean your machine has been compromised in any way (and it has likely not been).  I have never received an email from Google of this nature.  I have received notifications when someone has attempted to create an account with my name in which they basically say that there is no action required if you're the rightful owner.
