How many model of lenovo notebook PC has been set this way (for the so claim of saving battery)?


all of them except the W700 (and possibly W500) have been limited.   i haven't tested a W500 or heard anything about it to know whether or not it has been limited.

Re: T61 Support SATA II ?

Hi Erik,

 

I have one of those new generation SSD drives that is capable of 250MB/s Read 100MB/s write.  Because Lenovo decided to limit the speed of the interface to 1.5Gb/s my drive is running at a fraction of what it is capable of.  On my non-lenovo desktop the same drive runs much faster since it supports 3.0Gb/s SATA II.

 

Lenovo must provide a way to turn 3.0 Gb/s back on.  I understand that at the time the 61 series was engineered decisions were made to save power but that decision is going to come back to haunt Lenovo.  The second generation of SSD drives are going to start shipping very early next year and you are going to have a bunch of irate customers.

 

Just put a setting in the BIOS and be done with it. 

 

I still don't understand how Lenovo never expected SSD speeds to bypass 150 MB/s. It's no secret what Intel and others have been working on for the last year. Especially with the NDA roadmap meetings I'm sure you have with them. 

 

Thanks

You are right, turning off the feature with battery life saving is hard to justify. One may not run Thinkpad on battery all the time.

If my data is still on cache of harddisk. I expert a full tranfer rate support.

 

I put the same disk to my other Acer notebook. It is noticable faster although both notebook use the same intel chipset and CPU speed.

Erik,

 

Is this a limitation within the BIOS or is it a modified ICH8 ?  As an owner of an X25 SSD I am disappointed with the current Lenovo results and hope for a solution.

Erik,

 

What is the channel to escalate this to an engineer and follow-up if there is something that can be done ?

 

 

Thank you

Sata speed is set by bios per intel's 965GM chipset specs, obviously there is no option to do that as of now through

Lenovo's bios.

 

Erik, I bought intel's x25-e for my T61 for Christmas , which theoretically should have about 200-250 MB/s throughput, all I am getting - 110-125 MB/s

It means, when I bought the laptop and expected per specs to have SATA II operational , I wasted my  money  ?

 

This is obviously has been a mistake by engineering team, I would really like to get my money's worth and have this corrected .


What would be a procedure to do that ? Any way to contact engineering team and put this request in ?

 

I am assuming more and more people are looking to get SSD's this year - seems like a priority and important fix , no ?
