When Intel launched its Santa Rosa platform, many new
features were added to improve notebook performance. Intel bumped the front
side bus to 800MHz, added new Merom-based Core 2 Duo processors along
with Intel Active
Management Technology 2.5, the GMA X3100 integrated
graphics solution and the Intel Wireless Wi-Fi Link
4965AGN Draft-N network adapter.
The company also announced NAND flash-based Intel Turbo
Memory which is aimed at improving performance and increasing battery life for
notebooks in Windows Vista. Intel claims that Turbo Memory (which is available
in 512MB or 1GB varieties) can provide up to 2x faster
loading times with applications and a 20 percent decrease when booting
Although Intel makes these claims for Turbo Memory
performance, the results in the real world haven't been as promising.
Hewlett-Packard has publicly stated that it hasn't been impressed with Turbo
Memory performance and that its notebook computers will not carry the feature.
"We have done quite a bit of research on this [to see]
whether there is any true value for our customers, rather than taking what is
available and putting it in," said HP's Steven Gales to ZDNET
UK. "We added 1GB of RAM and saw a much higher improvement in
performance compared to using any of the ReadyBoost or Robson technology. If
you have enough system RAM in the system already, ReadyBoost doesn't give you a
HP also took issue with the fact that the use of Turbo
Memory onboard a notebook locks out the customer from adding a ReadyBoost
compliant Secure Digital card or USB thumb drive to improve system performance.
"A customer can have more flexibility with an SD card
or USB key because they can choose for themselves (when to add it and) pick the
price point at which they want to add that technology. We're not forcing them
into paying X and being locked into 512MB," Gales continued.
Finally, HP showed concern over the price of the Turbo
Memory module. HP points out that Intel charges around $50 for the 1GB module.
On the other hand, a consumer could pick up a 2GB Secure Digital card for
around $20 and get roughly the same performance boost in Windows Vista.

This cache buffers disk writes and allows the disk drive to stay spun down for longer periods of time to increase battery life and the overall reliability of the drives in mobile systems. Serving data from the non-volatile cache increases the performance of the boot and resume processes as well as disk- and memory-intensive applications by avoiding the latency of random disk I/Os.
