Windows 7: ReadyBoost - Setup and Use

About the same as a SSD with USB 2.0. But that was not the point of discussion. The point I wanted to make is that now every USB stick lends itself for Ready Boost. One has to compare the access time of the stick to the access time of the HDD.

Hello 24x24,

Since you will have to have RAM installed in your computer for it to run, then no. If you have very little RAM, say 512MB, then it would use ReadyBoost a lot more. However, using ReadyBoost instead of having more RAM would decrease your computer's performance. RAM is always faster.

Hope this helps,
Shawn
i thought it was all to do with the paging file that normally runs on c drive by default what readyboost helps with not ram??

Hello Brian,

It's a combination of both. If you have low RAM, then you will be using the paging file more. If you add ReadyBoost, then it will use it in combination with RAM and the paging file to help improve performance if the USB drive is faster than the HDD. Unfortunately, most HDDs these days are faster than a USB 2.0 drive. I don't think that they will be until USB 3.0 flash drives are out and plugged into a USB 3.0 supporting motherboard.

Hello Kucing,

Usually it will only matter if the USB flash drive is faster (most likely not) than your Windows 7 HDD where the paging file is on will it help improve performance. Having more memory on the USB drive just means that there is more than can be allocated for ReadyBoost to use.

When USB 3.0 flash drives are out with supporting USB 3.0 motherboards, then ReadyBoost might be useful again to help performance if you are low on RAM with a slow HDD.

As Shawn pointed out, many USB sticks are slower than the HDDs. There are, however, some that are very fast in access times - some are below 1ms. Those are useful for Ready Boost even if the data transfer times do not match the HDD values.

I therefore recommend to test the devices with HDTune to determine the data and decide on the basis of that. Below you find an example of an average HDD as compared to 2 sticks - both are the same make and model but watch the difference in access times.

In my estimation, the data transfer rate is of a lesser importance since a page activity transfers relatively small amounts of data.

That's a very good point WHS.
