SATA III IN MACPRO 2009 and ML?

I have to replace two RAID drives and want to know if WD Black Caviar 2TB SATA III will be compatible with my MP 2009 and OS 10.8.3.
Thanks.

The fastest available rotating drives can source a burst of data off the platters at about 1G bits/sec. That is less than SATA I.
1) Which version of SATA is supported is not a limitation for most uses. Modern rotating drives are backward-compatible.
2) Do not pay extra for advanced SAT Bus speeds, as you will not see an improvement in performance based on faster transfer rates. It ends up being "More Headroom " not "More performance".

  • Update 10.8.2 from 10.8.1 fails with MacPro 2009 and ATI HD 5870

    I tried to update my Mac Pro 2009 from 10.8.1 to 10.8.2, after the download and install of 10.8.2 my mac completly hang in a white screen mode with broken graphics. No chance to fix that - i nearly tried everything. All hardware is okay, as i went back to 10.8.1 from a cloned drive.
    Yes, the configuration of my mac is complex, here is a list:
    Mac Pro 2009  2x 2.66 GhZ Quad-Core
    96 GB RAM - 3x 16GB + 3x 16GB
    ATI RADEON HD5870 1GB
    Apple RAID Card installed (with 4 drives raid 5 attached)
    Apple Fibre Channel Card installed (2x 4GB Fiberchannel)
    Monitor NEC PA301W
    Booting from a Crucial M$ 512MB SSD
    Again: All works perfectly fine on 10.8.1.... As I went back through a cloned drive.
    BUT it`s impossible to boot the machine even from an attached (firewire) clean installed 10.8.2 (i tried that too)
    10.8.2 worls perfectly on my the Mac Book Air, no prblems upgrading at all- BUT did anybody know of a bug - especially related with the ATI HD 5870 in an MacPro 2009 ?? I repeat myself, all works perfectly great on 10.8.1 but there is as of now no chance to go up to 10.8.2 without getting a white blank screen.
    So please, did anybody had the same problems with the ATI 5870 ? Or with the Apple Raid Card or Aplle Fibrechannel 2 Port Card? Is it the combination within my Mac Pro?
    I would really appreciate any tipp, help or support !
    Thanks!!!

    After successfully installing 10.8.2 from 10.8.1 - which never worked with 96 GB (6x 16GB) on my Mac Pro, it worked perfectly with reducing the RAM to 48 GB. See posting above.
    After the 10.8.2 Update I added again 16GB to a total of 64 GB - WORKED!
    Then I tried it again with all 6x 16GB (3x 16 + 3x 16Gb) FAILED ... again the same frozen broken screen on 10.8.2 - whitch works PERFECTLY under 10.8.1 (!!)
    Last not least I added 1x 16GB more, so right now I have 3x 16GB on Bank 1 + 2x 16GB on Bank 2 - in total 80GB and it WORKS!!!
    The memory is fine ! as i changed the different RAM Modules, so it`s NOT a defective RAM Module. For me right now the solution is either to run 10.8.2 with 80GB OR 10.8.1 with 96GB.
    I guess this really has to be a BUG, or has anybody else another idea WHY 96GB RAM work on 10.8.1 and (in my case max. 80 GB RAM) work only in 10.8.2?
    Maybe this solves some problems for other with >64GB RAM installed when they want to upgrade from 10.8.1 to 10.8.2 .... If you can run your system with more than 80GB PLEASE let me know. Right now I have at least one spare 16GB module.
    so that config is working now:
    Mac Pro 2009  2x 2.66 GhZ Quad-Core
    80 GB RAM - 3x 16GB + 2x 16GB
    ATI RADEON HD5870 1GB
    Apple RAID Card installed (with 4 drives raid 5 attached)
    Apple Fibre Channel Card installed (2x 4GB Fiberchannel)
    Monitor NEC PA301W
    Booting from a Crucial M$ 512MB SSD

  • Sata III hard drive cable compatible with older generation of macbook pro

    Would my macbook ( 17 in mid 2009 ) be compatible with a new hard drive cable ( sata III ) ? I upgraded my hard drive to Samsung Pro 840 and wanted to upgrade my sata II cable to a sata III for faster read and write. Is this possible?

    Dave The Newbie,
    replacing the cable will not increase the interface speed, just as putting racing slicks on a minivan won’t make it a dragster. I have the same model SSD in my Mid 2010 MacBook Pro, and my MacBook Pro’s SATA interface is limited to SATA II, just like yours. Unless you’re planning on mainly running disk-bound apps, it’s not something that you’ll need to worry about — just enjoy the SSD as is.

  • Macbook Pro 2011 SATA III support

    I would like to know if the new Macbook Pro 2011 supports SATA III SSD's. I know the thunderbolt needs the Sandy Bridge to work, however I am not sure if that means that the chip will definitely support a SATA III SSD. Does anyone know ????

    Eww,
    Thank you very much or your response. I have a clarifying question. I am looking at buy a OCZ VERTEX 3 SATA III 2.5" SSD and I just want to be sure that if I spend the money on it I am going to get 100% functionality to include the 6/Gbps, minus of course the TRIM feature because from what I understand Apple locked it out. Do you know if this drive will work on the 2011 MacBook Pro.

  • G62-340us Sata III

    Need to replace hard drive on my G62-340US.  Can I use a SATA III drive with 500GB and 7200RPM?

    HP will provide a replacement Hard Disk Drive if the Notebook warranty is Active, If not you need buy a SATA Hard Disk Drive from a retail shop nearby
    Please make sure you are getting at least equal capacity as the original one in order to use Recovery Disks. If you need you can buy a larger, but not smaller capacity Hard Disk Drive. For example if you have a 500GB Hard Disk Drive you can upgrade it to 750GB Hard Disk Drive but not 320GB Hard Disk Drive
    Note: Back up all the personal data to an external drive if it's possible. Otherwise you could connect the failed HDD via SATA to USB adapter with another PC or same PC after replacement of HDD & re-installation of OS and try copying /recovering the files.

  • PCI SATA III card on 2006 MacPro

    I'd like to instal a SATA III SSD on my macpro to use it as scratch disk for photoshop and other software.
    To be able to use all the speed of the ssd I wont to instal a pci sata III card... but I don't know if there are cards compatible with my 2006 macpro
    Could you help my?
    Thanks
    Daniele

    Yes, if your SSD is new SATA3 6G, and also, to not have to share, to off load, the scratch to PCIe
    Mac Pro is very limited in just how much I/O bandwidth there is even with 4 internal SATA ports it is less than 1Gb, less than even 250MB/sec per port in real world.
    Ideal is to max out RAM to 24GB first or instead, then dedicated scratch disk or array.
    Much much more:

  • On my Macbook pro 15 2011, System Profiler is suggesting that it uses SATA III for the hard drive and SATA II for the Optical Drive.  Is that true?

    On my Macbook pro 15, 2011, System Profiler is suggesting that it uses SATA III for the hard drive and SATA II for the Optical Drive.  Is that true?

    That is correct. The tech specs indicate:
    Hard Drive Interface
    6.0 Gbps Serial ATA (SATA)
    Optical Drive Interface
    3.0 or 6.0 Gbps Serial ATA (SATA)

  • I have a late 2011 mac book pro and I'm wondering if it uses SATA II or SATA III for the hard drive? Which eventually I'm going to replace with a SSD.

    I was wondering if the late 2011 macbook pro uses SATA II or SATA III for the hard drive. The reseason I'm asking this is because some day I'm going to replace the Hard drive for a SSD drive down the road and would like to use all the performance of the SATA controler.

    SATA III.

  • Right, MacBook Pro 17" early 2011(Built March) and my new OCZ sata III 6G not working, when is Apple going to admit there is a problem with the Intel's 6 Series Chipset. In System Information it says "Link Speed: 6 Gigabit" which is sata III.

    My MacBook Pro 17" early 2011(built March) and my new OCZ sata III 6G are not working together, when is Apple going to admit there is a problem with the Intel's 6 Series Chipset. In System Information it says "Link Speed: 6 Gigabit" which is sata III and in my MacBook Pro it does not work. 
    Now MacBook Pro 17" early 2011 built May onward do not have this problem it was fixed in the Intel's 6 Series Chipset. (So there is a problem). Cam I have my MacBook Pro fixed please.

    After biting the bullet and ordering more RAM, my computer now is working a ton better. So that must have been the main issue. With 8 GB RAM, I can now even run Parallels fluidly (better than my work PC!) where before simple things like logging in to my MBP after reboot could take forever.
    The place I went to had several other people getting RAM upgrades at the same time as me, so between this and other comments I've seen in discussions here and elsewhere on the Internets, I take it to mean that either Apple should bump up the base RAM on its new machines, and/or stop charging so much for additional RAM.
    I refused to believe a Pro machine bought with Lion installed would come with too little RAM for light to medium usage, but it was apparently the case. I'll mark this as a correct answer and hope some other poor soul will come across this thread and be helped by it.

  • Big Problems with Samsung Series 830 SSD SATA III (256GB) and W520

    Hi,
    i get my W520 last week with an normal SATA 500 GB Drive, at home i changed it to a Samsung Series 830 SSD SATA III (256GB) and install windows 7 64bit pro via recovery media.
    I was wondering, startup was taking very long .... from starting windows to the logon screen 1.45 minutes ... Now i tried a new recovery, same issue, tested the harddisk which is in good state.
    I changed back to the 500GB Drive, startup take only 30 seconds around....
    Are there any known issues?

  • SSD Upgrade - SATA III Compatible Macbook Pro 2009

    Hi there,
    Just wondering if someone could clarify this for me please:
    Looking to upgrade to an SSD, a high end model. I want to spend around £250, but I'm not after lots of GB's as I'll be happy to move my media to an external drive, which is what currently uses 90% of my HDD space.
    Anyway, I was looking into the OCZ Vertex SATA III, but after some searching around I'm not sure if the MB Pro has the ability to handle SATA III at 6GB's, so would be totally pointless paying extra for the SATA III capabilities.
    Could someone just clear this up for me please, and if anyone could suggest a make/model for me? I'm looking to spend £250 tops, although like I said, i'll settle for little storage space. I'm really after just the quickest one I can find for that price. Looking to upgrade in time for a clean install of Lion, then I can take a lightening quick MB with me when I start med school in September!
    Thanks guys!
    Harrison

    Unfortunately, without your actual Mac model how can we tell if it supports 6 Gb/s SATA?  You can check the specs for your model at support.apple.com/specs/.

  • GD-85 and SATA III

      Guy's, have a new build on the GD-85 with a single WD black sata III HD. On the marvell controller post screen it shows the drive running as SATA II. The drive is connected to the white MB SATA connecters, using the MSI supplied
    SATA cable, no jumpers on the drive. HD tuner shows the HD running as SATA II in win 7.All drivers are loaded in win 7 and the device manager shows all controllers. I'm missing something in the BIOS to get this HD into SATA III mode,
    what is it that I'm missing?
    Bruce

    How many red ones do you have?  Look closely at each cable.  There should be specifications information printed onto them.
    I just found the following document on this site: http://www.sata-io.org/developers/technical_library.asp
    http://www.sata-io.org/documents/SATA-6Gbs-Fast-Just-Got-Faster.pdf
    Page 4:
    Quote
    The same cables and connectors used for current SATA implementations can be
    used to connect SATA 6Gb/s devices. SATA-IO recommends utilizing quality
    components to ensure data integrity and robust operation at the fast 6Gb/s transfer rate.
    Cables already at the threshold of 3Gb/s operating margins may experience lower
    performance than expected at 6Gb/s due to an increased number of resends.
    Not sure if this has to do anything with you issue but it still makes me scratch my head.

  • Sata-II or Sata-III -- R945 and Z935 series

    are R945 or z935 laptops series support sata-III ??

    I have the Z935 and from Device Manager I can see the Intel(R) 7 Series Chipset Family SATA AHCI Controller.
    From the Intel web site that is part of the HM77 mobile series chipset. That chipset includes USB 3.0 and SATA III.
    I upgraded to a Crucial M4 256GB mSata III SSD and I get read speeds in excess of 300 Mbps as measured by HDTune.
    So I believe the Z935 is truely SATA III. I cannot speak for the newer R series models.
