Macbook Pro Link Speed 1.5G instead 3G

It doesn’t seem anybody from Samsung reads this forum. I submitted a support question, here: http://kb.sandisk.com/app/ask/

A member of our support team will get back to you soon.

That would be SanDisk support and engineering doesn’t seem to read this forum. 

Hi 

I have the same problem as all from this thread and many other. My MBP is middle of 2009 (macbook pro 5,4) and nvidia 

MCP79 AHCI and my sata speed shows 1,5gb. I brought few days ago SANDISK SDSSDX-120G-G25 and can’t get my money back (live in Russia… ). So i wonder to know how long we need to wait for fix? Why OCZ can do it? Where the hell information about solving problem? It’s so difficult to tell people that engeneers will fix this problem in 2 month or half of year. What should people do? just wait and hope? 

 

p.s. sorry for my bad english, hope you will understand me.

I’ve submitted now a question to Sandisk on http://kb.sandisk.com

A good description of the issue, with information from another users attempt to get status on a fix for this: http://amzn.to/RAf85T

This reviewer states that LSI has pending firmware fix 5.0.3 and 5.0.4 for SandForce controllers. They tested 5.0.3 on Sandisk Extreme, and it fixes the TRIM issue. No word on if they have fixed the fallback to 1.5 G with Nvidia controllers issue.

Today we’re re-testing the SanDisk Extreme 240GB SSD with the new 5.0.3 firmware that fixes TRIM and keeps the drive running at extreme speeds. Like many Team SandForce manufacturers, SanDisk is not releasing 5.0.3 to the general public. A very small issue was found in 5.0.3, but 5.0.4 will fix the issue and we have confirmation that 5.0.4 will be ready for your flashing pleasure in less than a month.

nice…:smiley:

Hope that this solution will came out asap!!!

Is anyone else experiencing the occasional lag/freeze? Happens every 30-60 seconds; beachballing and what not. Running an iMac from early 2009, 480gb extreme with 1.5gbps link speed. This is seriously annoying. 

Do you have any SMART probing software running in background (like iStatPro, TemperatureMonitor) ?

I had these kind of freezes in the past on a magnetic disk, disabling SMART queries did the trick. 

Does anyone knows when the firmware will came out? i can’t wait more time… :stuck_out_tongue:

i think never, i’m already died…

Tried disabling iSTAT Pro + other ‘SMART’ apps, no dice! Still getting those annoying freezes. Is there any way to monitor these queries if you’re unsure what other apps may be making the call?

Come on sanddisk tech support says something. I know that you are waiting for the public release of sandforce firmware but please tell us something.

Is there any word if the Sandforce 5.0.4 firmware will include a fix for this fallback to SATA I problem with the

NVidia controllers on legacy MacBook Pros that support SATAII (late 2008-to and including early 2011)?

Thanks.

Sandisk release the update. Use the 5.0.4 even it that have issues.

I think this will be the last product that i bought from sandisk. I have some sd and mmc cards and adapters but i never thought that support has so bad. :cry:

For me is for sure: i will never ever buy nor suggest to anyone sandisk products.

You definetly right, will never buy any of andisk products. NEVER EVER! YOU KNOW WHAT SANDISK? YOU ARE S****T

Contacted Sandisk support a few months ago, said they may (or may not) correct this bug in a future firmware release.

I guess our best move is to talk about this on twitter @SanDisk @SanDiskSSD @SanDiskSupport

There is all kinds of misinformation in this thread, really a mess.

A little history first. The Nvidia SATA chipsets were a huge failure, they had all kinds of problems and are infamous for their inability to work with SATA III SSDs. Nvidia no longer makes any SATA chipsets, and has not done so for years. Even worse, they provide no support for them at all, as in driver updates. The manufactures that used the Nvidia SATA chips also have not provided any updated drivers. It is the Nvidia driver program that is the source of the problems with SATA III SSDs, or really any SATA III device.

It is the SATA chipset and driver that controls any HDD or SSD. All any drive can do is provide the SATA speed protocol data to the SATA chipset, drives cannot control the SATA chipset interface. The Nvidia driver is not up to date with the current SATA protocol, but is also so bad that it can’t even try to use SATA II, and just shifts to SATA I. NO OTHER SATA chipset that only supports up to SATA II speeds does this, all the AMD and Intel SATA II chipsets stay in SATA II mode with SATA III drives. The only SATA chipset that has this problem is the Nvidia.

OCZ tried to fix this problem with the Nvidia SATA chipset, with a special program that changed the SATA speed protocol data in (only) their Vertex 3 SSDs, from SATA III to SATA II. Apparently it did work, but of course the SSD then became a SATA II speed drive even when connected to a SATA III supporting chipset. Doing that was a violation of the SATA standard, and no other SSD manufacture has provided a program like that. Check the forum of any SSD manufacture, and you’ll find threads about this Nvidia chipset problem with SATA III SSDs. This is not a SanDisk or a SandForce issue, it is all Nvidia’s problem.

So on one hand we have the obsolete, out of production Nvidia SATA chipsets, which Nvidia refuses to support with driver updates, and the companies that used those chipsets also refusing to provide driver updates, while those chipsets are still in use by their customers. On the other hand we have SSD manufactures that have nothing to do with Nvidia and their failed, unsupported SATA chipsets, and have built their products to the correct PC industry and SATA standards. Yet when modern SATA III SSDs don’t function correctly due to the flaws of the Nvidia chipset, people blame the SSD? It simply does not make sense.
