6Gbps SATA
Twenty eight days after Intel launched its Sandy Bridge microprocessors, it announced the stop-shipment of all 6-series Sandy Bridge chipsets. The first shipping version of these chipsets (B2 stepping) was affected by an unfortunate "oversight" that could cause failure in the four 3Gbps SATA ports that branch off the chipset. The remaining two 6Gbps SATA ports were unaffected by the bug.
Most notebooks only use two of the six SATA ports supported by most members of Intel's 6-series chipset family. If a notebook design used the 6Gbps ports exclusively, the notebook would be fine to ship using the flawed B2 stepping parts. With the 3Gbps ports not in use the bug would never show up. Notebooks that used more than just two ports or used at least one of the 3Gbps ports would be affected and would have to be remanufactured with a fixed version of the 6-series chipset. Intel promised to begin shipping fixed (B3 stepping) 6-series chipsets by the end of February.
Apple announced and started selling the 2011 MacBook Pro lineup on February 24, four days before the end of the month. Surely that would be too soon for Apple's manufacturing partners to have received B3 stepping chipsets, built boards around them, integrated them into MacBook Pro designs and shipped them half way across the world to Apple stores all around the US.
Naturally Apple wouldn't comment on what chipset revision was in the 2011 MacBook Pro, so the first thing we did was check to see what SATA ports were in use on our systems.
Here we have the high end 15-inch MacBook Pro. I installed an Intel SSD 510 in the lone 2.5" drive bay and it is connected via a 6Gbps port internally:
So far, so good. The only other bay in the new MacBook Pro is used for the optical drive. And it's connected to a:
...3Gbps SATA port. Uh-oh.
Apple doesn't directly report chipset IDs under OS X. I installed Windows 7 via Boot Camp and headed over to device manager to pull the device ID of the SATA controller: 1C01.
Cross referencing with Intel's datasheets I found that there are two revisions of the SATA controller: 04 and 05. The latter is used in the "fixed" B3 stepping chipsets. And what do we have here at the end of the hardware ID string for the SATA controller?
REV_05.
This is a B3 stepping chipset. In fact, Apple's manufacturing partners seem to have received B3 chipsets before anyone else given that boards were produced, tested and shipped in time for a February 24th launch. It would appear that Apple was among the first if not the first company to receive B3 stepping 6-series chipsets. Although I had concern for the health of the Apple/Intel relationship over the past couple of years, it looks like the two are back to being bedfellows.
Internally there are no visible changes to the MacBook Pro's primary SATA cable. It's still a flex cable but apparently capable of delivering twice the bandwidth of last year's model. Apple doesn't ship the new MacBook Pros with any 6Gbps drives and I would be surprised if it selected anything other than Samsung or Toshiba for SSDs, which means even the SSD options are 3Gbps. Luckily I happen to have a small cache of SSDs, including a bunch of new 6Gbps offerings.

I'm really considering splashing out on the 13" but I've read countless articles and all I hear is the glossy screen is either horrible or awful. I don’t want the 15", I need the portability and I don’t know what on earth to do!??????????Then comes the SSD issue, if I want this option I have to wait 6 weeks!
I can always get this later down the line I guess?? Well from what the article suggests??
Any help (opinions) would be great as right now I’m lost! :(

If a person bought a MacBook Pro in the last 18-24 months,I don't see the reason to upgrade unless you're on the Bleeding-edge of performance needs and Mac your living with your Mac. Many Apps and advanced Software aren't even optimized to take advantage of multiple Cores,or Hyper-Threading/Turbo Boost. I don't care as much for Auto Switching Graphics,since I have total control of my Graphics with my March 2010 MacBook Pro 17"/Core 2 Duo/2.8 Ghz/4GB RAM/AG/500GB HD/512MB or 256(IG) VRAM-dual cards/express card. if I was buying new today,Hyper-Threading and Turbo Boost schemes would be OK,but there's no way that I'd trade or sell my machine for these updates! To me,speed hasn't been an issue in 2 or 3 years! My 2006 20" iMac was at 2.0 Ghz,and the newest Macs are 2.0-3.0Ghz or so. I know that Sandy Bridge is faster than a Merom Core Duo,but most improvements seem to have come from adding more Cores and RAM,so that more tasks can be done simultaneously! I don't care for gimmicks,Turbo-Boosting,Hyper-Threading,and poorer graphics to convince me to upgrade my Macs. Unless you are a Digital Video Content Creator,or other high-powered user,or your Mac is 3 yrs. Old or so,you should Max-out your RAM,get a faster HDD or an SSD,rather than buying a Whole New Mac! If you have the money to spend,good for you,but a combination of Power,Battery-Life,and Portability,are the REAL issues! I wish people would stop telling others that they're Idiots for paying Mac prices,since it's our Money,and only YOU can determine what's good value for the Performance,elegance,and Stability of Apple Hardware!rredge - Thursday, March 17, 2011 - link
Today, the local Apple store acknowledged that my 15" MacBook Pro is not functioning properly and refunded the purchase price despite the fact that I was just past the 14 day return period.The problem is that the computer ceased to respond to the trackpad even when rebooted with the power button.
In the course of trying to figure out what the problem was, I discovered that there are reports of people experiencing similar problems for all three models (13", 15", 17") on Apple's support forum, where one thread alone now runs 19 pages, as well as elsewhere on the internet.
The Apple store personnel told me that Apple has not acknowledged that there is a problem with this line of computers, although they acknowledged in less than two minutes that my computer has a problem sufficiently serious to warrant a refund out of the return period. I declined a replacement because they expressed ignorance of the issue, indeed said that Apple did not acknowledge an issue, and were unable to give me any assurance that a replacement would perform any better.
The questions at this point are how widespread this freezing problem is and whether Apple is going to acknowledge it and fix it.

The second paragraph should have said that the computer ceased to respond to both the trackpad and keyboard.nitrousninja - Thursday, March 17, 2011 - link
I saw the benches but I dont know if that translates into a big real world difference in SSDs. I'm mostly doing stuff in Word/Excel, some light video editing/converting, and occasionally some WoW. This would be in the base model 13"Should i go with the stock 3GB 128GB SSD or the OCZ 6GB I can get at Microcenter and install it mysel?. I've never done that on a Mac.
Thanks for the help!

Doubt you're still wondering but, if you want to have any space left after installing an OS and still want an SSD then you should splash for the 128GB SSD or wait till a reliable larger SSD is available. I wouldn't go less than 120GB.As to whether you should get an SSD, just ask yourself this question:
Have you ever sat, even for a moment, and wondered why an otherwise well specced (but magnetically driven) computer seemed slow?
If yes, then you'll likely be able to set that question aside by putting in an SSD.

Hello Rredge,how frustrating your experience sounds!
2011 was the year I was finally supposed to buy myself my 1st ever MBP after 18 years in the Windows environment.
It took me long enough to choose between a 13-inch or 15-inch one but then I started reading about these freeze issues a lot of users have been facing. being French i only heard about this problem within French forums and i was hoping this would have to be a specific problem for a batch of units delivered in France but now I have to admit this really is a larger scope problem.
For what it's worth there were comments on the forums I went through about I-Stats being a cause for these problems as it installs by default with a settings that take over the fans control.
Did you have that app on your computer?
Best regards
Tranksen

Bonjour Tranksen,The fan on my computer was acting normally when this happened and I do not have that widget installed. I was running Terminal, TextEdit and Safari and the processor was under extremely light load.
You will find a good deal of discussion about this problem on the Apple U.S. support forum at http://discussions.apple.com/category.jspa?categor...
This is not an imaginary issue. Apple agreed to the return of my computer for full refund despite it being outside the 14 return period.
I would consider repurchasing one of these computers, but not until Apple clarifies what the problem is and fixes it.

You said that noise was an issue with the larger MPB, but I'd like that to be quantified in decibels and compared to other laptops in a table, in future reviews.Omid.M - Monday, March 21, 2011 - link
Can the AT team comment on this please:http://apple.slashdot.org/submission/1504006/2011-...

Can you guys duplicate this issue? Is it just simple overheating and poor design on Apple's part? I really want to know...
Also tweeted to the three of you. Thanks for your thoroughness, gang.
