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.

Help: Slow Crucial C300 256GB SSD in 17" MacBook Pro (2011) via SATA III 6Gb/s

Computer: 2011 17" MacBook Pro
Drive: Crucial C300 256GB
Drive Firmware: Revision 7
Bay: Main Drive Bay (6Gb/s)
OS: Lion 10.7.1
I did a fresh install of 10.7.1 and I'm getting these speeds on the above configuration:
Here is the same test run on my previous computer, a 2008 Mac Pro, with SATA II (same exact drive):
What is going on here? The Mac Pro with SATA II was running the C300 faster than the brand new 17" MacBook Pro 2011 running SATA III. This drive should be getting up up to 355MB/s read on SATA III.
Can someone please help me figure out why this drive is not running faster in my computer?
Thank you in advance.
FYI - I did install the new EFI 2.2 Update that was released in September. The above tests were after I installed the update! So you can rule out that I didn't install this update that supposedly fixed SATA speed issues on these Mac's.

I solved it. Xbench didn't give the best results. I tried other benchmarking tools and concluded that I am getting the SATA III speeds on this drive on this MacBook Pro.

Is my MacBook Pro early 2011 SATA II or SATA III ? Model Identifier: MacBookPro8,1

Hello all,
I'm thinking about updating my HD to a SSD to give my "mature" MAC an speed bump.
QUESTION:
Is my MacBook Pro early 2011 SATA II or SATA III ????
Model Name: MacBook Pro
Model Identifier: MacBookPro8,1
Processor Name: Intel Core i5
Processor Speed: 2.4 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache (per Core): 256 KB
L3 Cache: 3 MB
Memory: 4 GB

Hold down the option key and, under the Apple () menu, select System Information. Under Hardware, look at the SATA/SATA Express tab and you'll see:
6 Gigabit is SATA III speed.
Good luck,
Clinton

I'm on the East Coast, USA. Here are my stats. I think they're more like what you are looking for.
1. Do you have any internet security or firewall app on there???
2. Have you gone to your Network Preferences, and clicked on "Assist Me?" It could be a setting is messed up.
3. How much RAM is in your MBP?
4. If you are near an Apple Store, I would take it in and have them troubleshoot it for you.

Corsair Force GT issue on MacBook Pro Mid-2010 (Sata 2)

I just bought the Corsair Force GT 120 GB to use as the only hard drive in a MacBook Pro Mid-2010. 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 in Mac OS X Lion 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:
-I have installed all available updates.
-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.

Why is the MacBook Pro Serial ATA transfer speed half that of the new iMac?

I have a MacBook Pro 2.4 GHz 15.4 inch with a Seagate Momentus 160 GB, 7200 rpm, serial ATA, PRT hard drive. This hard drive has a serial ATA transfer speed rating of 3.0 Gigabits per second. The MBP logic board has an Intel 965 chip set that has a serial transfer speed rating of 3.0 Gigabits per second. I was at the Mac Store the other day and noticed that the new iMac 20 and 24 inch computers (that have the same intel 965 chip set) have an Intel ICH8-MAHCI speed rating of 3.0 Gigabits per second. My question is why does the MacBook and MacBook Pro's only have an Intel ICH8-M AHCI speed rating of 1.5 Gigabits per second? Attached is a copy of my Serial-ATA information:

For several reason although the main one is that the vast majority of 2.5" drives have a 1.5Gbps interfacce. Drives with a 3Gbps interface in this size are rare where as they're very common in the 3.5" drive size which is used in the iMac.
Additionally you'll find that few drives do in fact make use of this larger bandwidth. For instance, the fastest 3.5" SATA drive one can buy for an iMac/Mac Pro up to 500GB is in fact a Western Digital Raptor 150GB which has an SATA I 1.5Gbps interface. So the interface bandwidth isn't everything. Yes there are faster drives than this now but they are in the 750GB size and up.

Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
So to sum up, the symptoms I'm seeing:
MacBook Pro CAN see internal SATA hard drives.
MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

UPDATE: An interesting development!
I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
Onward!

2 issues with MacBook Pro Retina - Fan randomly speeds up and USB3.0 Issues

So I just purchased a brand new MacBook Pro Retina 15" 2.40GHz.
Randomly, when nothing but finder is open, the fans will spin at full speed.
I have opened every application on the machine including serato, ableton, photoshop, VLC playing a 1080P movie, iTunes playing music and youtube playing videos in 2 tabs - and the fans do not spin as fast at it does when nothing is open or running (confirmed with activity monitor too).
Secondly, once I eject a USB3.0 drive from the machine, I have to reboot the system before the drive can be mounted, or even recognized at all by the computer. (it does not even show up in disk utility till the reboot). this happens with 2 seperate USB3.0 external hard drives that work fine on other rMBPs. This happens with both usb ports too.
I have reset SMC, PRAM, ran all Apple updates as well as reinstalled the operating system (as well as booted from a known good system in target disk mode).
Please help

There are a few threads reporting the fan issues you are dealing with which you might want to look at. I have now experianced it with four brand new 2013 rMBP.

Macbook pro: Extremely slow upload speed

Hi,
I know this question has beed raised many times before me, seemingly from hundreds or thousands of users, but none of the threads I have found has lead to any solution.
My new Macbook Pro (15 inch), using Lion 10.7.3, is simply unable to obtain anything but an extremely slow upload speed, when using Wifi. I am using an Apple Airpor Extreme wifi device. My work PC, my older Macbook Pro (13 inch), all tablets and telephones etc hooks up to the same Wifi device and obtain all the speed they should, but my new Macbook Pro is sloooooooooooowwwww and sometimes cannot even initiated an uload speedtest at i.a. www.speedtest.net.
As mentioned, I am aware that there are plenty of threads on this, but I am not aware of any that provides a solution.
Is there a solution or is my new Macbook nothing but crAplle?
Best regards,
n

My subscription is 10 Mbps downloadand 2 Mbps download. upload
I get that (10/2 Mbps) on all other devices, other than my new Macbook Pro.
On my new Macbook pro I get 10 Mbps download, but only from 0 to 25 Kbps upload.

Macbook Pro Fans at high speed

My macbook pro has been running at high speeds, non-stop, for a few days now. I tried resetting the SMC, but that did not work. Any suggestions?
Thanks!

Macbook Pro fans run max speed constantly.

I have one of the pre-aluminum body Macbook Pros, a 2.2 Intel Core 2 Duo with the 15" monitor. For the past few months, both my fans have been running full blast (6000+ rpms) from boot to shutdown. I've tried reseting the SMC, PRAM, and even the misleading "Repair Drive Permissions," but my fans stay full blast. Using Activity Monitor and the Terminal command to check CPU usage, When I have Firefox open everything runs with about a 89%-90% CPU idle. No strange printer problems sucking up my CPU, not watching youtube videos, just high fan speed. I'm hoping it's not a logic board issue. Any suggestions?

Hey, just dealt with the same problem...I think it is finally solved!
Online people offered all sorts of suggestions about the activity monitor, printer queues, etc. Nothing worked. Then I remembered that when I updated to Snow Leopard, it warned me that ONE OF MY APPLICATIONS WAS INCOMPATIBLE.
I searched everywhere (e.g. application support, preferences) and deleted EVERY SINGLE SHRED of that application (Viruscan from McAfee), even the plist files. Finally, no more fan running hot for no good reason!
Hope you can remember which of your apps was incompatible, if not, you may want to delete non-essential applications you have downloaded. Good luck!

MacBook Pro fans won't speed up

I have a MacBook Pro (Early 2008) 2.6Ghz with a 200GB drive and 4GB RAM.
The problem is that i.e. I'm creating a movie in iMovie, so the computer does a heavy task, the CPU works at lets say 75% and according to iStatPro, it's temperature reaches 80-82 Cº, but the fans won't go over 2500 rpm! Is that normal? Because I'm pretty sure that when I first got the machine almost 2 years ago the fans would go much faster on occasions...
I noticed the problem while I was still in Leopard, and now that I upgraded to Snow Leopard it continues...
I tried the SMC reset but nothing happened. Should I be worried? I always use a fan pad underneath my MacBook Pro and I still get these temperatures! What should I do?

Hi spyros_1,
I find that the fans are "reactive" rather "proactive" in cooling the machine. With that being said, I don't really hear my fans fire up until the temperature on the machine begins to reach the low 70s (Celsius). However at 80 degrees, the fans are usually humming closer to 6000rpm than they are to 2500rpm.
The other thing, I've noticed a few separate instances where iStat Pro does not report the correct reading. Over the weekend, my fans were very audible and iStat Pro reported that they were at 2000rpm (idle).
It might be worth bringing the machine in for diagnostic, just for peace of mine.

2011 MacBook Pro 17 SSD SATA 3 6G problem

Has anyone found the fix for this yet or know if Lion changes the SATA behavior at all?
I know the early 2011s have been identified as having problems with 6G operation and SSD and it has been hit or miss.
I picked up a OWC 6G SSD and the shielding cable to see if I had one of the lucky builds and it seems I did not.
Only the main bay negotiates 6G and the speeds are fast but I see random Drops in performance with AJA System Tests. It seems
to be a problem with negotiation or so I think. When my machine displays random "Write" speed drops it will stay consistent until a reboot.
The same if I display "Read" drops or the combination of both. A reboot or sleeping the laptop results in a reproducable change in behavior by either
clearing up the problem if it had one or picking up one if it did not. A series of reboots and AJA tests allow me to arrive at a state where I am showing consistant
good read/write without drops but it only lasts as long as I have not powered off or slept the machine.
Does anyone with Lion show any differences when it comes to the 6G SSD issues? Or has anyone gotten any help from apple with this since I know it has been documented many times now.

Lion has not yet been released. Discussion about Lion beyond the public information would be forbidden. Anyone here who knew something as yet undisclosed would be violating an NDA with Apple.
In short, we can't answer your question.

Slow firewire 800 speeds on early 2008 macbook pro 17"

I've got an early 2008 macbook pro 17". I'm transferring files between a WD mybook studio II (2TB) configured as raid-1 to a sata dock with a seagate 1TB drive daisy-chained over firewire 800. both 1TB drives in the WD mybook and the 1TB seagate in the sata dock are 7.2k rpm. I'm running a block-level clone FROM the mybook TO the seagate using Carbon Copy Cloner which i would think would be the fastest real-world test i could do. I'm getting pegged speeds of 40MB/s. This is on par with other regular read/write speeds i've noticed in the past. this seems way off. to remove variables i unplugged my two firewire 400 drives (as i've heard that may slow things down, even though they're not doing anything during the clone) and it SLOWED DOWN the fw800 clone to 38MB/s ! plugging the two firewire 400 drives back in during the clone brought the speeds back up to 40MB/s. i don't have a unibody 2009 mbp that had the firewire issues.
1) HDD's should read at 70-80MB/s and at least write at 59 MB/s, why am i not getting that using firewire 800 and two 7200 rpm drives ?? (i know the wd mybook is raid-1 but i'm reading from it...shouldn't effect read performance)
2) (less important) why on earth would having two firewire 400 drives plugged in and inactive make the firewire 800 transfer speeds go up/down 2MB/s
i'm willing to experiment with anyone's suggestions. huge thanks in advance.

i have a similar problem.
i have a new seagate freeagent 1tb drive w/FW800, FW400 and USB2.0 ports, and its connected via the FW800 port/cable to my macbook pro, and read/write speeds are really slow, particularly read speeds.
i'm currently working on an audio project with around 15 audio tracks running at once, and it chokes the drive ('HD overload' errors), so i've done some benchmark testing using Drive Genius and Xbench. the results show that the drive is averaging around 12mb/s read speed, and around 26mb/s write speed. grim.
i tried the drive with the FW400 connection on my missus' old imac g5, and its much faster than my mbp's FW800 connection, so i decided to try the drive back on my machine with OSX booted in Safe mode, and benchmark it again. the results are massively different; the FW800 connection is very fast (as you'd expect).
both the tests were done with all my peripherals attached (usb hub, ethernet cable, usb2 ext. drive) so i don't think the problem is with those.
what i'm wondering is if there are any known system extensions that can screw with the FW bus speeds? if not, any pointers as to where i should start troubleshooting?
many thanks!
