w500 with 4GB TurboMemory

Any thoughts on speed compared to 2GB TM?

the 4GB TM is available for w500 no the canadian website

 

If you have more than 2gb of ram, turbo memory will have no performance gain.
get ram, not turbomemory. their bandwidthes are not comparable.

 

Turbo Memory is pretty much a scam. Like tianxia said, just get 2+ GB of RAM and you're set.

 

As I said:

What are you basing that on? The only benchmarks I've seen were when turbo memory first came out and I havn't seen anything since then. That meant they were based on the initial driver version with the initial 1 gig version of the memory on Vista before SP1. There is a chance the 2 gig memory that is used now is faster, the driver is improved, and the changes made in SP1 also could improve the performance.

I hate making assumptions off really old data. And if there is a 4GB option then the new turbo memory is 4 times the size of the original making its performance even more likly to be different.

Also the larger turbo memory means a larger readydrive cache. That in turn means the HDD may be accessed less which in addition to perf reasons also means the drive can spin down more leading to a longer battery life.

Of course all this requires benchmarking to see if any of this holds up.

 

Agreed, there's no new data. That's why I got the TM on my new t400 - worst case senario I take it out, if it causes problems.

 

Actually they will add some nice features to Turbo Memory 2, according to the first page here on NBR. From what I can read it will be user programmable, so to speak, as you will be able to chose what to keep there in order to load faster (or something like that).
