New 15'' PB SuperDrive&hard drive performance

Hi!
I would like to ask those who already have the new 15''PB with HD display if you have noticed any performance drop while copying files from Super Drive to hard drive, or while burning DVD? The new machine is supposed to have the Super Drive and hard drive on the same bus, which would suggest a potential bottleneck...
Thanks for sharing your experience.
Richard

That's a good question I would like to know too. I just read that fact yesterday and wondered the same thing.
Okay, so who is going to test it?

  • Maximizing external hard drive performance

    I just purchased a new 300 GB external hard drive for my intel Mac mini. Since I´m new to the Mac world, I was wondering what I can do in order to maximize its performance. I´ll use it for storege and its current format is FAT32.
    Should I reformat it to GUID? Should I partition it?
    Many thanks for your help.

    If you really need maximum performance for audio/video you should consider
    -Mac OS Extended (without "journaled")-.
    But for storage and backups select -Mac OS Extended (Journaled)- for safety reasons and you would not recognize less speed.
    I partitioned my external in two.
    One for CarbonCoppyCloner backups of my Powerbook drive.
    One for backing up iPhoto librarys etc. and as EyeTV archive and buffer.

  • I just saved my iphoto original library to my external hard drive, now how do i create new space on my hard drive and create a new iphoto library

    i just saved my iphoto original library to my external hard drive, now how do i create new space on my hard drive and create a new iphoto library

    Trash the copy of the library you just moved. Then Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
    But do you want to have two iPhoto Libraries? Why not just use the one on the External?

  • The first time I connected my new My Passport portable hard drive to my Mac, the message asking if I want to use the drive to back up with Time Machine did not appear.  What is the next step?

    The first time I connected my new My Passport portable hard drive to my MacBook Pro, the message asking if I want to use the drive to back up with Time Machine did not appear.  I would like to set it up to do this.  What would my next step be?

    Drive Partition and Format
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Open Time Machine preferences to select this drive for use as the backup drive. Turn on Time Machine.

  • HT1338 I was backing up my MacBook with Time Machine on my new (correctly formatted) external hard drive.  It was going fine when my 2 yo knocked the hard drive.  Now TM said "failed" and the Mac refuses to recognize the external hard drive.  Help please?

    I was backing up my MacBook with Time Machine and using my new (correctly formatted) external hard drive.  All was going well when my 2 yo knocked the disk leading to a "failure" by time machine (Latest Backup:  Failed).  Now the MacBook will not even recognize the hard drive.  I have rebooted, tried all I can think of, but no acknowledgement of the drive.  The drive itself makes noise and vibrates as if working, but nothing from the Mac.  Please help or $100 down the drain...  Thank you.

  • HT1349 I had to get a new computer as my hard drive went and lost everything. How do I get my itunes library back?

    I had to get a needed to get a new computer as my hard drive died. How do I geatr my ituens library of songs back?

    The easy way is from the backup you make of your computer so in case something happens you don't lose anything.
    You can download some media files purchased from Apple:
    Downloading (using iOS or computer) past purchases from the App Store, iBookstore, and iTunes Store - http://support.apple.com/kb/ht2519 - enabled with iTunes 10.3 and newer; not all media formats are available in all countries (see: iTunes in the Cloud and iTunes Match Availability by Country - http://support.apple.com/kb/HT5085); apps, books (not audiobooks), music, t.v. shows, and movies (some - not all studios have permitted this).  Downloading previously purchased movies and TV shows requires iTunes 10.6 or later.  Discontinued items not available. For items not included in the iCloud list (e.g., ringtones), or locations or computer systems where iCloud is not (yet?) available, you only get one download per fee paid.  Apple notes it is your responsibility to back up your purchases.
    Select the store on the left side of iTunes.
    Click on Purchased on the right side under Quick Links.
    You can re-download your available previous purchases.
    This will not reconstruct your library as it was.  It just puts the media back.  You will have to do playlists, ratings, etc.  If you have music from another source you will have to get it from there again.

  • Switching iTunes (older version) from an old latptop with mechanical issues to iTunes on a new computer.  The hard drive, issue free, was placed in external drive enclosure.  How do I recover iTunes?

    I'm trying to moves iTunes (older version) from an old latptop with mechanical issues (non working screen, keyboard, and battery) to iTunes on a new computer.  The hard drive, issue free, was placed in external drive enclosure.  This was a cost effective way instead of dumping lots of money in an outdated old laptop while I can invest it into a new laptop.  How do I recover iTunes?
    I'm switching from a 3G phone to a blank 4GS in the process.  I would like to have everything that was on my 3G phone and iTunes on my new phone and computer.
    Thanks

    iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527
    Quick answer if you use iTunes' default preferences settings:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

  • How do I create a new folder in my hard drive - free agent go flex drive - on the mac book air?

    FORMAT TYPES
    FAT32 (File Allocation Table)
    Read/Write FAT32 from both native Windows and native Mac OS X.
    Maximum file size: 4GB.
    Maximum volume size: 2TB
    You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
    NTFS (Windows NT File System)
    Read/Write NTFS from native Windows.
    Read only NTFS from native Mac OS X
    To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
    For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
    Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    Maximum file size: 16 TB
    Maximum volume size: 256TB
    You can use this format if you routinely share a drive with multiple Windows systems.
    HFS+ ((((MAC FORMAT)))) (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
    Read/Write HFS+ from native Mac OS X
    Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
    To Read HFS+ (but not Write) from Windows, Install HFSExplorer
    Maximum file size: 8EiB
    Maximum volume size: 8EiB
    You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)
    EXFAT (FAT64)
    Supported in Mac OS X only in 10.6.5 or later.
    Not all Windows versions support exFAT. 
    exFAT (Extended File Allocation Table)
    AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    Maximum file size: 16 EiB
    Maximum volume size: 64 ZiB
    You can use this format if it is supported by all computers with which you intend to share the drive.  See "disadvantages" for details.

  • Installed a new seagate 160GB internal hard drive

    I installed a new 160 GB internal hard drive. Reinstalled operating system, but the hard drive says it's only 31.37 GB. I've tried to erase the disk and restart from the installation DVD, etc. but it won't read it as 160 GB hard drive.
    any suggestions?

    Hi, jumpintoliquid -
    Welcome to Apple's Discussions.
    ATA hard drives use jumpers to set their address as Master or Slave.
    Some drives also come with an additional jumper, which is used as a limiter to set an artifical size for the drive to approx 32GB. This is done because some (older, I think) PC CPUs could not address a volume larger than that.
    The solution would be to remove that extra jumper (or reset it according to the jumper config label on the drive). This drawing from Seagate's site may also apply to your drive -
    http://www.seagate.com/images/support/en/us/u5family1.gif
    Edit - also, be sure the address jumpers are set to Master if it is the only drive on the bus.

  • Improved Hard Drive Performance...KT3U2R

    I have tried the recent tweaks to get my hard drive performance up. Someone mentioned to me that the on board controllers were not the most efficient and that I should spend 30 bucks on an external controller card to DRASTICALLY improve performance. I have two 80 GB Seagate Barracuda Drives. Does this sound like a logical conclusion to you?

    Ignore it.  I've had and/or tested a ton of hard drives on VIA chipsets and from the KT133 on, they have all performed as well as on Intel chipsets, and in accordance with credible reviews.

  • Open thread for new purchase of external hard drive

    I have 4x 500 GB drives and 2x 250GB drives that I want to consolidate to one drive. I have trusted LaCie and recently (in the past 2 years) have been happy with the G-Drives as well.
    To my suprise (and shock really) the Mac geniuses I spoke to at the Calgary Apple Store said their techs use the WD 500GB Passport drives all the time. Super durable etc etc. but I was in need of 2 TB. I was torn between the G-Drive and the WD My Book Studio. The difference in cost was about $70. Historically, I've had the "don't trust western digital for Macs" running through my head ever since I heard it.
    However, I was convinced to go with the Western Digital My Book Studio 2TB (it's not a "new" company), but I've found that every time I boot up the drive, it runs the proprietary software which I don't intend to use. So far, I'm not finding any luck on how to get around this as I'm told it's "built into the firmware". Also, after my iMac goes to sleep, the drive disappears and I have to shut it off and turn it back on to bring it back.
    What would you recommend for an external hard drive for long term storage (not to be used for time machine or iPhoto or iTunes)?
    Would you recommend I take the WD drive back and get my head checked?

    I'd return it for something else or a refund, but that's just me.
    I too was shocked upon a recent visit to an Apple Store when I saw WD external drives for sale. One salesperson told me she was shocked that they were carrying them but that other staff member had told her that the WDs were now performing well for Mac users. I don't know what to make of it.
    I find the external drive market to be confusing. I'll just say that I've been happy with an Iomega 250 GB triple interface drive that I bought 4 or 5 years ago and am happy with a 1 TB OWC Mercury Elite triple interface drive that I bought a couple of months ago.
    Both these drives came WITHOUT any of the proprietary software so I didn't have to face the hassle of removing any of it.
