Computers And Laptops With Turbo Memory - What Actually Doest It Mean

You may find the new laptops in the market are now comes with “Turbo Memory” feature which is actually an internal flash memory fit inside the laptop. This can be used to increase your cache memory without dangling memory sticks. Its a feature that is already available as "ready-boost" in Windows Vista And Windows 7.

To Know exactly what read boost is, read my previous post. Windows ReadyBoost | Use Your USB Pen Drive As RAM | Easily Boost Windows Performance.

  • When ever you realize more memory is required for smooth running of Windows 7 
  • With many applications got installed on it. 
  • While RAM upgrade is not possible...
The next best option for you was to use Flash memory (USB flash drive) with Readyboost feature in Windows 7. Flash memory is non-volatile, cheaper and can service random reads up to 10 times faster than a typical hard disk, whereas physical hard disk Random Disk IO is still a bottleneck. As per Windows 7 Team Blog ” Windows 7 will disable Superfetch, ReadyBoost, as well as boot and application launch prefetching on SSDs with good random read, random write and flush performance”.

ReadyBoost will leverage the flash memory storage devices by creating an intermediate caching layer on them that logically sits between memory and disks.Windows ReadyBoost relies on the intelligent memory management of Windows SuperFetch feature and can significantly improve system responsiveness.

Configuring Windows ReadyBoost is as easy as booting your OS, but many people are not discovering this hidden feature. When a removable memory device such as a USB flash drive or a secure digital (SD) memory card is first inserted into a port, Windows 7 checks to see if its performance is fast enough to work with Windows ReadyBoost. If so, you are asked if you want to use this device to speed up system performance. You can choose to allocate part (you can even allocate the full available space) of a USB drive’s memory to speed up performance and use the remainder to store files. See the screen captures below which explains the steps you go through while enabling ReadyBoost.

Select ‘Use this Device” and decide how much RAM you want to allocate. The maximum space from one Flash Drive can be allocated for Readyboost is 4GB. So use multiple Flash Drives for Readyboost if you want more than 4GB.





Once Readyboost is done, you will see a Readboost Cache file as shown below in the figure.



You can measure the performance using perfmon utility – choose “Readyboost Cache” object . As can see in the below screen capture, I have used two flash memories for readyboost and allocated 6GB in total (in Red) and used space is 2gb at that moment (in Green).

First flash drive has been allocated with 4GB, and remaining for data store. In the second one, I have allocated 2 GB and remaining for data store. I feel faster now working on my netbook than without having it.
