I was just told by a Lenovo CS rep that the W520 doesn't support 6Gbps for "data integrity" reasons

The main HDD bay in my W520 drops from 6Gbps to 3Gbps shortly after boot. The speed drop is triggered when I start to pass data over the port. I can take the same drive (Vertex 3 240GB) and put it in the ultrabay and I get full 6Gbps speeds. It seems pretty obvious to me that this is a problem with the SATA controller on the laptop's motherboard (my specific laptop, not the whole run; other prople have the same drive with no issues), but after arguing with Lenovo support for over a week now, a customer satisfaction rep just sent me this email:


"I was able to confirm with are technical support that SSD transfer rate for the W520 ThinkPad is 3,0GB/s (chipset has the capability but we limit it for data integrity). So, your system is working as designed. 

One bay for removable devices, Ultrabay Slim-compatible, 12.7mm high, bottom access 
Some: Solid State Drive (SSD) / SATA 3.0Gb/s, 2.5" wide, 7mm high 
Some: HDD / SATA 3.0Gb/s, 2.5" wide, 7mm or 9.5mm high, Active Protection System 
All: removable, upgradable, supports the second disk, Shock Mounted Hard Drive"


(w/ a link to this: http://www.lenovo.com/psref/pdf/tabook.pdf)


Obviously, these numbers refer to the speeds of the drives that Lenovo sells, not the speed that the port itself is capable of. Additionally, there are dozens of people that have confirmed that the main bay is capable of 6Gbps speeds. I also confirmed this with several sales reps before I purchased the laptop.


How should I handle this? He is going to have his tech support people call me back tomorow, but I seriously doubt they're going to be very helpful.

Yes. I've tried the latest drivers from Intel's site and the unreleased version that's floating around, too.

<QUOTE>

[UPDATE for 4/6/2011] A little over a week ago I sent some questions into Lenovo around the drives and storage for the new Sandy Bridge based notebooks.  Here are the questions and the answers I received.

1. Are the supported SATA interface speeds on the new ThinkPad's SATA III 6GB? Specifically, is this true for the T420, T420s, X220, X220t, T520, and W520?

[Lenovo] Yes, The new Huron River ThinkPads will support 6Gb/s, but our current drives that have been certified are only 3GB/s drives. The current roadmap is showing Late 3Q or early 4Q is when we'll qualify 6GB/s drives. This is true for the T420, T420s, X220, X220t, T520, and W520.

Might be totally pointless, but can you clean the SATA connector on the main bay? Maybe some contamination and interference is forcing it to drop to lower speeds?

I don't want to state the obvious, but what if OCZ's Vertex 3 is defective? Also, I recently had a problem with SATA drive where it would degrade shortly after bootup, and turns out there was a tiny crack on the flat ribbon cable where it connected with mobo. It's easier said then done, but make sure cheap cable is not defective.

If the drive itself was defective, it would not work at 6Gbps in the ultrabay.

 

I'll open it up and have a look at the cable.

How can I check my speeds for you in the main drive slot?

Run CrystalDiskMark or AS SSD Benchmark and post screenshots please. Thank you!

How exactly are you testing this drive and drawing that conclusion?  The question earlier in this thread is a good one. How do you know your drive isn't defective?
