I recently got a 8GB flash drive to move around my portable apps, as well as some music, and simple data files. It’s bigger than I probably need for now, but I figure I’ll grow into it pretty quickly. Since I currently have a lot of free space on it, I figured why not put that space to use, and speed up my computer at the same time, so I turned on ReadyBoost. It’s simple, here’s how to do it:
- Right-click on your flash drive icon. In my case, mine is the E: drive. From the menu that appears, choose Properties
- In the Properties window, select Use this device. If you want to change the suggested amount of space to use, move the slider or type in the amount you desire. Mine suggested 4GB, which is fine for now.
- Click the Apply button, or just click OK and ReadyBoost is activated.
You’ll now see a file called ReadyBoost.sfcache (it will just display as ‘ReadyBoost’ if you have your extensions hidden on your flash drive that takes up the amount of space that was set in the Properties window. If you want to free up that space, just return to the Properties window and disable ReadyBoost.

ReadyBoost speed-up the system ???
USB Flash Drives are very SLOW to use as cache.
HDDs are very quicker than USB Flash Drives. Use these as cache, not Flash Drives!

My laptop, and many current models now, have a built in SD slot which is much more convenient thatn hanging USB drive off the side or back of your laptop.
Anyway, I currently have 2 GB SD memory card dedicated to just ReadyBoost and I just couldn’t use any SD memory card. I guess the SD memory card needs to have fast read and write performance if you plan to use a built in SD card slot. At first I assumed that an 80x SD memory card would be OK but Vista rejected it. I then tried a “high speed” SD memory card recommended for use in digital cameras and digital video recorders (which I think are also 80x) and found it to work.
As to speed improvements, I’ve been running with it since February 2007 and where I’ve noticed the performance has been with the launching of applications that I use on a regular basis; Outlook 2003, MSIE, Word, Excel, Adobe Acrobat Reader and OneNote 2007. These apps do load up much faster with ReadyBoost.
Some argue that what I’m experiencing is prefetching performance. If that were the case then why did load times drop by a good full 2 to 3 seconds when ReadyBoost was not being used?
To touch back on the SD memory card, I’ve now begun to see “Vista ReadyBoost Certified” labels and stickers now on many of the SD memory cards on the shelf.

Flash card are VERY SLOW comparated with HDD.
HDD is 20-40 Mbytes/s (RAM is 10-20 times faster), but
Flash memory tipically can’t reach HDD speed, then use HDD disk system cache (pagefile).
If did you add a 8Gb HDD instead of 8Gb Flash memory, you think to it as a added RAM ?
Of course you have more free GB on HDD than on USB or SD card !
I disabled ReadyBoost at all because it SLOW the system, with his very slow memory cache.

Hi, download this free utility http://crystalmark.info/software/CrystalDiskMark/index-e.html
If you have better speed with flash memory than your HDD speed then you can use ReadyBoost.

According to programmers’ team to have benefit with ReadyBoost you must have a Flash memory with MINIMUM Random (not sequential) Write Speed (512K) of 1.75 MB/s (HDD is about 30-35 MB/s) and Random Read Speed (4K) of 2.25 MB/s (HDD is about 1 MB/s).
You can test all these speeds with free CrystalDiskMark above.

neat tip but windows tells me that there is a cache already on another drive, how do i force it to use my 1GB sd card (well its a 1GB microsd card in a sd card adapter which i had lying around)

Readyboost is meant for less powerful systems to handle the stress. But it does add some kick when needed. 1 GB SD card in the slot helps.
