Thank you, Erik. Glad to know that something is going on. I'll wait one month before taking further actions.

t61 does not operate at SATA-II speeds?!

2009-02-14, 2:34 AM

why doesn't the t61 operate at sata-ii speeds?  the sata chipset supports it but it seems like the max read speed is only 150MB/sec.

 

are there going to be any bios updates that fixes this BIG BIG problem?

There will be a story on the situation to come out on Wired on Tuesday , probably should embrace servers - traffic might increase a bit.

Just to show that this is not only an T61 Problem.

Re: t61 does not operate at SATA-II speeds?!

All,

 

I've investigated this issues at length through engineering and have received the following explaination of SATA data rates available on the Santa Rosa ('61) and current Montevina based systems (T400/T500, W500, W700, etc)...

 

"For Santa Rosa-based systems, the Intel ICH8 supports a SATA bus speed of up to 3.0 Gb/s. Lenovo made a design decision to prioritize maintaining compatibility with Ultrabay disk drives, which are connected via a SATA-to-PATA conversion chip which could not handle a 3.0 Gb/s SATA bus speed reliably. Therefore the system was standardized to 1.5 Gb/s.

In testing rotating media drives, our measurements show data throughput difference between 1.5 Gb/s and 3.0 Gb/s bus speed is less than 5% since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.   

For those customers who choose to purchase an after-market SSD drive capable of SATA bus speeds up to 3.0 Gb/s, the system will interface with them at 1.5 Gb/s. Lenovo's official position is that the Santa Rosa systems are working as designed.

The Montevina based systems which began shipping last year have direct SATA interfaces for both drive bays and are enabled at a system level for SATA bus speeds of 3.0 Gb/s performance. Current Lenovo drives have firmware set to 1.5 Gb/s data rates.

Exchanging these drives for after-market drives which support SATA bus of 3.0 Gb/s should provide for the higher data rate at the overall system level. Again, it should be noted that our performance measurements show less than 5% performance improvement between 1.5 Gb/s and 3.0 Gb/s SATA bus speeds for rotating drives, since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.

After-market SSDs which support SATA bus speed of 3.0 Gb/s will operate at that bus speed. Depending on the data transfer test method used, your actual data throughput from a 3.0 Gb/s SATA bus speed should be 220-250 MB/s and about 90-120MB/s throughput when running on SATA bus of 1.5 Gb/s. This is due to the bus signaling used for the SATA bus, as well as overhead for error checking."

This helped me too

Mark ,

isn't Ultrabay and main drive located on separate SATA channels ?

According to ICH8 specs chip able to negotiate different speeds on different channels ?

Just shows you that current Lenovo engineering is not what is used to be.

Turning down drive throughput performance, inability to hot dock/undock with the newer models.

Would be nice to get some good old IBM engineering and oversight back in there. It is going downhill.......

And especially interesting to note that an Acer laptop, which was bought for probably half the price, outperforms the supposed to be king of notebooks... If I only could use an apple!!!!

Mark, thanks for your clarification.

 

I'm pretty sure there are alot people that don't use a second PATA hard disk in the Ultrabay. I understand compatibility comes first, and that's why it's speed capped. Anyways, is adding an option in the BIOS setting to be able to switch between SATA1 and SATA2 impossible? After adding those two options, the developers can add a comment on those settings saying SATA1 for Ulatrabay 2nd HDD or something like this.

 

When using mechanical hard disk drives, no one would really care if it is SATA1 or 2. I don't think it will be even 5% difference. You can tell the engineers, they made a good decision back then, different story now. People are starting to move towards faster SSDs like intel's X25-M or X25-E, and at some point, find out the speed cap, google, and see answers like 'congratulations, you just discovered the speedcap on thinkpads'. They sure will start complaining about it. This is not just 5% difference here we are talking about when using SSDs. It is more like 100% difference when justs looking at Disk reading speeds. This won't traslate directly to x2 faster system, but still, limiting the capability is totaly wasting money on consumers point of view. I really hope something can be done to unleash the SATA cap.

 

 

Thanks,

Hoon
