13" Mbp Only 1.5gb Sata ? - SOLVED!!!!!!!!!

[ImaBigD]

You guys all rock! WE DID IT! I'm proud of everyones efforts to pressure Apple into releasing a firmware so quickly. This is how an effective campaign is run. This should serve as a lesson - there is power in numbers.

Here are my new benchmarks with a 3.0 Gb/s controller.

Those numbers would be more useful if you compared them to the 1.5Gbs results. 😕

Glad I got the update, I can now think about an SSD now 😀

Did an Xbench before and after the update, and as I thought, there's no noticeable speed increase with my HDD... but that was expected.

Looks like the performance is worse for HDD after firmware update. Anybody confirm? If that's case, I will walk away from the update.

 

[tsubikiddo]

Well Done, you guys rock!

wt more needs to be said?😎

 

[Belm]

Even more impressive is that's 2009 and they still allow themselves to state something as ludicrous as this. Ho well, who cares?
We can now safely buy the MBP range without remorse or fear that in a few months time our new gear would be relatively obsolete.

Again, kudos to everyone.

Exactly

Here we go again...

The difference in the numbers is well within the variational limits between runs. If you run the test multiple times on the same setup you'll get slightly different results every time. The performance is not any different with the new update.

Here's a before and after from my Corsair P256: Biggest gains in sequential reading and writing, although I did see some modest gains in the random section as well. Honestly though I think I would be hard pressed to notice these differences in anything other than very specific tasks (i.e. large sequential writes)

I think my results may give you a more complete overview of the XBench scores from stock to SSD (at 1.5 cap) and now with SSD and (3.0). This history is on a the new 13" MacBook Pro, 4gb, 250 gbHDD, and then upgrading to the 256 GB Corsair SSD.

Hope this is helpful to those interested to see the actual upgrade values. I gotta admit, I'm very pleased with the user experience on this MacBook with the upgrade to the SSD drive. YMMV

Before and After

Here is my before and after test

13" MBP 2.53GHz, 4GB, Intel X25M 160gb

 

[baseline01]

Here we go again...
The difference in the numbers is well within the variational limits between runs. If you run the test multiple times on the same setup you'll get slightly different results every time. The performance is not any different with the new update
Ruahrc

Ho god, thank you for this. You beat me to the punch.
Yes people, these are marginal differences (3 ~ 4 decimal points) in I/O transactions measured in MBs per second, you won't feel a thing believe me.
But those of us working with bulk inserts into transactional databases sure will.
Can't wait to install my new vertex on to this baby 😀

Cheers

 

[Nistilian]

The drive was less then a week old.

That really sucks. You should be able to return it as defective, right? What about manufacturer's warranty?

Intel fedex'd me a new one on a cross ship.. I should have it tomorrow morning.

 

[Jiten]

Although I'm not directly affected by this, I'm extremely happy that Apple fixed this problem. It just shows that its good to complain and make ourselves heard - unlike certain apologists who defend the mistakes of Apple and thus get in the way of progress. 😀

 

[Slurpy2k8]

Now I can recommend the new laptops to my niece (and maybe one or myself as well). 😎

Yes, because your niece's usage would certainly have been crippled by that 1.5Gps transfer speed, right? How old is she? Was she planning on using a raid SSD array? Or running SATA benchmarking software for fun? Because if not, then I don't see how this changes anything for her.

I always wonder if these types of posts are satire or not. Unfortunately, I doubt they are.

Ha, you gave MR the credit for Apple fixing this? Do you really think this vocal minority has that much power. I can assure you there were people at Apple (like the employees and engineers) that noticed this amongst many other of Apple's customers that brought this issue up. 😛

Dude what are you talking about? Your post is discriminatory towards young people, like they are not somehow able to tax a computer via multimedia and gaming usage? Why do you think he should have recommended it anyway when an obvious problem was built into the machine? Maybe you should be less arrogant and short sighted.

[ImaBigD]

Read the EFI upgrade page. It says "MacBook Pro EFI Firmware Update 1.7 addresses an issue reported by a small number of customers using drives based on the SATA 3Gbps specification with the June 2009 MacBook Pro..."

Who do you think the vocal minority of those "small number of customers" represents? Very likely, the hundreds (if not thousands) of us who have been posting to forums like this one and yelling and screaming at Apple via their feedback. The Mac Rumors thread had 1,600+ posts and the Apple Discussion thread had over 20,000 views.

Yes, I give credit to the "small number of customers" that forced a giant's hand (in this case, an Apple). In the end, they didn't need to release this upgrade - it doesn't affect their core customers who don't intend to upgrade one bit - but it affects the vocal minority, who expected a "PRO" product and was unwilling to accept an outdated SATA.

We are loud, and we are proud. Viva la revolution!

This what I expected before. Also the system profiler is now showing the SATA bus as 3Gb.

I see everyone's comparison stats and I'm trying to figure out why mine looks so poor?

Because it looks like you have a standard hard drive and not an SSD drive. Is this correct? The big gains are coming from people with fast SSD's like the Intel X25 models. But that was the whole point of this....it wasn't about regular drives but the newest versions of SSD's that are very fast.

Ooops. Yes I do 🙁

Question though. Why would my system be slower after the firmware upgrade?

5-10% or less differences are negligible.
