3079WM SATA speed (SATA 1 or II)?

Hello,
I am trying to find out the sata controller/SATA speed used in my laptop (3079wm). I have scoured the net and am unable to confirm its speed. I want to install an SSD drive into the laptop but am wondering if its worth it or not due to possible bandwidth restrictions (I am still considering just putting the money into a new laptop.
Can anyone confirm what the speed is?
CPU-z info:
Motherboard 363A
Chipset: AMD 785G
Southbridge: AMD SB700
Thanks for the help.

Do you think there is a possible program that can read SATA speed? I've been looking for years until I quit looking for it. If you have any update on this, I would also want to know.
HP Pavilion DV5..
and still working perfectly..

  • My MacBook Pro 2010 unable to link with SSD at SATA 2, 3 Gb speed

    I have a MacBook Pro 13-inch Mid-2010 that I used with the standard 5400 RPM HDD for about a year. Last week I decided to replace it with an SSD, the Corsair Force GT 120 GB to be more precise. I knew that my MacBook Pro model only supports SATA I & SATA II & that the SSD is backwards compatible. I expected (and still expect) the SSD to link up at SATA II 3 Gb speed.
    However, System Profiler gives the following information:
    NVidia MCP89 AHCI:
      Vendor:          NVidia
      Product:          MCP89 AHCI
      Link Speed:          3 Gigabit
      Negotiated Link Speed:          1.5 Gigabit
      Description:          AHCI Version 1.30 Supported
    Corsair Force GT:
      Capacity:          120,03 GB (120.034.123.776 bytes)
      Model:          Corsair Force GT                       
      Revision:          1.3.3
    Benchmark tests show my write & read speeds are at about 100 & 110-130 MB/s. I have searched for a while on this and other forums and not been able to find a way to get negotiated link speed at 3 Gb and then to check whether this solves the rather sluggish performance.
    Some extra info that might be useful:
    -The 1.3.3 firmware of the SSD is the latest available. There are also no updates available via Apple Software Update.
    -The SSD is the only drive in my system. After booting to the Mac OS X Lion DVD I had created, I used the disk tool to partition the new drive with the settings at GUID partition table & HFS+ Journaled. I haven't experienced any other problems.
    -I have reset the SMC, PRAM & NVRAM. This didn't change anything.
    -I haven't installed any Windows version using Boot Camp (yet).
    -System has Boot ROM Version:          MBP71.0039.B0B and SMC Version (system):          1.62f6
    Thank you in advance.

    Guys, have any of you tried these:

    Thanks, and cheers

  • Why is my hard drive not performing at the maximum Sata II speed?  MBP mid-2010 (macbook pro 7,1)

    I have a question pertaining to the factory hard drive in this Macbook pro mid-2010 that i have.  Currently my system profiler is showing that I am using only 1.5 GB/s of the maximum 3.0 GB/s allowed in the SATA II controller.  below are a couple of copy and pastes of the information on my Apple product.  Any help would be much appreciated before i have to go to the genius bar and battle it out with them.  I am using the operating System: Lion OS X 10.7.2

  • How to Reset the Sata Link Controller for Full Sata 3 speeds on an OCZ Agility 3

    So I purchased a new OCZ Agility 3 drive, installed it into the main bay of my 2012 Macbook Pro, and the drive was running at half speed. I called OCZ and spoke to the guys about how to resolve this issue, they were very knowledgeable, but they had no ideas how to make thier Linux Live Tool work on the Mac, which gives us the ability to reset the controller. Here's what I did to get the full speeds out of my OCZ Agility 3.
    - You will need a Windows computer, or the ability to create and install Windows on a Bootcamp partition on your Mac.
    - Thumb Drive
    - Lots of Patience
    1. Open Disk Utility and create one partition on your thumb drive under MS-DOS Fat 32. Click the Options tab and select “Master Boot Record.”
    2. Go to the OCZ forum and download the older Linux Live Tool version: OCZ_Tools_316-old.zip. From my experience, the newer version doesn’t work on the 2012 Macbook Pro.
    3.Download the “Universal USB Installer” for Windows, and follow the steps to install the ISO to your Thumb Drive using the instructions located on the OCZ Forum. http://www.ocztechnologyforum.com/forum/showthread.php?99275-NEW!-Bootable-Linux -based-tools-for-OCZ-SSD-s&p=714047&viewfull=1#post714047
    4. Once the ISO is successfully copied to the Thumb Drive, insert the USB stick into your Mac with the OCZ SSD installed in the Main Bay, Power On, and hold down the “Option” key. You should see a yellow hard disk icon that says “Windows,” select it and press enter.
    5. Once the OCZ Tool loads up, click the “Green Arrows” to put the drive into Sata II mode. Shutdown the computer, power on, and check the System Profiler. The drive should be running at Sata II speeds.
    6. Shutdown the computer and boot into the OCZ Tool, and click on the “Red Arrows.” This will reset the controller to its default mode of Sata III (Sata 6 Mode).
    7. Check the speed of the drive using the disk speed test of your choice. The drive should now be running at full speed.
    The biggest accomplishment here was actually getting the OCZ Linux Live Tool to load on a 2012 Macbook Pro. The newer version of the tool doesnt support the USB 3.0 drivers, so you loose the funtion of your trackpad and keyboard or bluetooth keyboard and mouse.
    **Note: Black Magic Disk Speed Test Version 2.0 may give you lower numbers than expected due to the compression method in testing the drive. I would prefer using XBench or Disk Speed Test Version 1.0**   
    ***Here's a link to a thread that explains how to properly install your OS onto the drive. If not done correctly, this can also cripple the speed of the drive.***

    I can almost see a big grin appearing in Bob's avatar... 
    Hopefully his reply has given you a clue already?
    If not, some explanation:
    Many settings in the standard "Media" panel (for both video and audio) don't apply for publications that need to go the Folio-way. This panel is mainly concerned with lovely Flash stuff, but apart from the Poster frame and the Markers, it is useless for Folio's.
    A quick guide: create a video with the necessary codec (H.264 for video, MP# or AAC for audio) at the required pixel size (exact width/height). Simply Place the file in InDesign, but don't scale it (or recreate and place a properly sized new video afterwards). Choose what to do with the Poster frame (and maybe some Markers), but all other settings are done in the Overlay Creator.
    Check Bob Bringhurst's Tutorials and his DPS Tips app for more info. But I guess you get the idea now.

  • Can G4 PowerMac MDD take advantage of SATA II hard drive speed?

    A PowerMac G4 MDD has 33Mhz PCI slots and a 167Mhz bus -- correct? Can this architecture take full advantage of a PCI SATA II controller card (if it exists for a Mac) and a connected SATA II hard drive w. 16mb cache operating at 3Gb/s? Or even a 1.5Gb/s SATA I drive? Thanks.

    Hi-
    Or am I trying to cram a V8 Hemi engine into my Mini Cooper, but just hooking it up to my 4-spark plug ignition system to run it on four cylinders?
    Aw, you outa get at least 6 cylinders worth out of it...and it will be one mean Mini C!
    The SATA won't run at it's potential, there is no doubt. But, you will see performance increases over the ATA drives, this is for sure..
    In my Sawtooth, after I installed the SATA drives, the speed increase was palpable. The SATA drives have better performance characteristics than ATA, and even without full data transfer rates, the increase in bandwidth, the speed of the drives, and the increase in cache definitely help performance.
    As for the question of SATA vs. SATA II, SATA II drives are all backward compatible to earlier SATA standard, so there is no reason to "limit" yourself to early SATA. Most all controllers are SATA II standard, and the SATA II drives are the latest in technology, and give the greatest benefit.
    I would recommend the Firmtek Seritek line of controllers. Bootable, and reliable.

  • 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.

  • Looking for Answers:  Bootcamp, WinXP, SATA drive speed

    Hey - I'm wondering if someone can pass along some info. I've yet to upgrade to 10.5 I'm running a 2.66 4-core MacPro under 10.4.11.
    I am still running the Bootcamp Beta and my original sp2 install of WinXpPro.
    And my SATA drives are dog-dead-slow! I've been looking around the net and most of the SATA/Drive/Bootcamp talk comes from early 2006.
    My thought was Bootcamp only installed Windows - and since I have already installed windows (for 2 pieces of graphics software), I wonder if I upgrade to 10.5 and the new Bootcamp, will my drives run at full speed?
    Thanks -

  • 2008 - How to make the SATA drives run full speed with Bootcamp and XP ?

    Has anyone found a way - after all this time - of repairing a 2006 install of Windows XP SP2 - or in someway fixing the rather slow SATA drive problems?
    I have not upgraded to 10.5 - but would if the new Bootcamp somehow (via new drivers??) fixed the problem!
    My machine is now 2 years old ( 2.66 4 core ) and I finally need XP's full speed for a project - but most of the posts I've seen are fro 2006 and expired.
    Help!

    And again, my objective to is get 'full speed' from the SATA drives while running XP.

  • MacBook Pro 9,1 SATA Speeds?

    Does anyone know what the internal SATA interface speeds are on the MacBook Pro 9,1? I'm planning on using OWC's Data Doubler to mount (2) hard drives in my MacBook and I want to purchase the fastest drives possible.
    Thanks!

    RE: SATA Bus speed:
    Rotating drives available today, whatever their SATA spec, can source data off the spinning platters no faster than about 125MBytes/sec.
    SATA 3 is rated at 6G bits/sec, which theoretically is about 750 Mega Bytes/sec
    SATA 2 is rated at 3G bits/sec, which is theoretically about 375 Mega Bytes/sec
    SATA 1 is rated at 1.5G bits/sec, which is theoretically about 187.5 Meg Bytes/sec
    None of the SATA Busses is a bottleneck for consumer Rotating drives you can buy today. Trying to speed up the SATA Bus will not provide any real-world performance increases for Rotating Drives.
    Even most common SSD drives are not bottlenecked by SATA 2.
    • Do not pay extra for SATA-3 over SATA-2.
    • DO pay extra for a larger Disk Cache, it will make a modest difference.
    • DO pay extra for an SSD over a rotating drive, it will make a difference.

  • External sata drive speed ...

    HI,
    I have an iMac G5 1.6GHZ. Am I right to say that I cannot benefit of the speed of an external SATA drive until I have a computer that has a SATA connection in the back ???
    Thanks in advance.
    Robert Lespérance

    Thank you ... That's speed !!!
    By the way, I want to buy one of these 2.5" external hard drive for my backups and move it around with me on the road. Do you know if the outside temperature could be a concern for the drive if I leave it in the car for a long period of time ??
    I understand though that I would have to let it warm up before using it once back !!

  • SATA link speed

    Hi, this topic didn't appear to be up here yet, so I'm going to ask it. When did the white MacBook switch to the SATA 3.0 Gb/s standard? I recently updated my hard drive to one that has 3.0 capability, but the link speed in the System Profiler says 1.5 only.
    Every bit of research I've done tells me that SATA hardware is forward- and backward-compatible, meaning the only thing standing between my new hard drive and its full capability is the MacBook's firmware.
    I noticed a recent firmware release for MacBook Pros that "unlocks" the faster standard, and it also mentioned that the newer white MacBooks have it already set up no problem. So my question is: Which model is the earliest capable of SATA 3.0 Gb/s? Also, if my late-2007 MacBook is not compatible...why is that? What is actually responsible for this limitation, if not firmware?
    Thanks.
    P.S. Your login link malfunctioned in Safari ("404 - We can't find the page you're looking for"). I had to use Firefox to post this message...my Mac was disappointed. Better get your "geniuses" on that

    Ah yes, I admit now to have forgotten to search the MacBook Pro discussion posts. That's the only place I now see a date mentioned.
    And indeed, this afternoon Safari allowed me to log in, after a week or so of "malfunctioning."
    Thanks for the answer, but I would still like to understand what part of the computer is responsible for the 1.5 Gb/s limitation, since serialata.org clearly states that its hardware is forward compatible.
    You have an impressive collection of devices; can I have one? :P

  • What should the real world transfer speeds be on the SATA drive?

    I've getting the following speeds on my Hitachi Deskstar drive that shipped with my MacPro.
    I read somewhere that the hitachi drives shipped running at a lower speed and one had to use the tools supplied on the Hitachi website (DOS disk!!) to enable the higher speeds.
    This is the reading from Xbench.
    Is this correct? 66mb/sec? Isn't this less than Firewire 800?
    Sequential 100.30
    Uncached Write 108.53 66.64 MB/sec [4K blocks]
    Uncached Write 101.51 57.43 MB/sec [256K blocks]
    Uncached Read 84.80 24.82 MB/sec [4K blocks]
    Uncached Read 110.85 55.71 MB/sec [256K blocks]
    Bit of a newbie to drive architecture, but what does the 3gb/sec come from???
    Thanks in advance

    FW is capable of 800 Mbps.
    SATA has a bandwidth of 3Gbps
    SATA 1.0 specifies a channel bandwidth of up to 150MB/sec theoretical.
    SATA 2.x specifies 300MB/sec.
    Compare that more to how Ultra160 SCSI shares or uses that for multiple drives (and there was some overhead and inefficiency that could result in loss of 10-15%).
    SATA Port Multiplier controllers can share that 3Gbps with up to 5 drives.
    My 10K Raptor has 84MB/sec writes, and about 75MB/sec reads.
    Xbench is not accurate.
    You might want to take a look at StorageReview -> Drive Performance DB.
    Most 7.2K drives, PATA or SATA, are in the 60-65MB/sec range today.

  • Problems with 17" 2011 MBP optibay sata speeds for SSD.

    I have a 17" early 2011 MBP.  I noticed that the optibay SATA is only 3GB/S.  Since I need to set up an internal RAID with SSD (SATA III 6Gb/S), and newer versions are now supporting this (I was under the impression that my earlier one would too), what are my options to get the optibay to work at the proper speed?  Do I need to replace the MBP?  Are there fixes that can be done by Apple repair?
    I need this for a number of on site video editing jobs that I need to complete over the next four months.  without the RAID set up, i don't see how I can do this.  I am also in process of getting the new thunderbolt RAID for in the office.
    Can anyone give me advice on how to address this issue?  I can swap the system as long as I can pull the current disk drive (and replace with the one that was delivered with the system), if that is what I need to do.
    Many thanks in advance.

    Hi David,
    What little I know about this for sure is that there are at least 2 different optical drive interfaces for the 2011 17" MBP.
    I bet you can guess the difference; iirc correctly, the ones that shipped early on have the SATA II interface, while later/current ones have the SATA III. You can check yours in System Profiler, but again, I bet you know already. Again, iirc, the early ones cannot be updated to run at SATA III/6Gbps.
    I don't know any of the above with 100% certainty, so I would continue looking/asking, but if it is correct, that means you'd need a new MBP (and need to make sure it's newer stock; what the cutoff is, I have no idea). fwiw

Maybe you are looking for
