Windows 7: Windows 7 Readyboost - How high can you go on 1 flash?

Windows 7 Readyboost - How high can you go on 1 flash?

Hey all I just came upon the concept of using readyboost with my computer since I usually run quite a few programs in the background while I'm gaming. I know it wont help much but just a little increase in performance is better than nothing.

I was just curious how much memory can be used on 1 flash drive?

I just bought a 16 GB Sandisk from Best Buy and when I used Readyboost with it the cap was 4 GB. I wasn't sure if the drive I bought wasn't designed to go higher or my USB port couldnt handle it. Then I wondered if the file format the drive was in was capping it so I can confused and thinking of buying a better one possibly designed for the readyboost. I was wondering if anyone could add some light to this situation and appreciate any feedback, thanks very much.

Welcome to SevenForums!

There is a 4GB limit on Readyboost. Due to the limitations of the FAT32 file system, the file cannot be more than 4GB.

I do not know what would happen if you formatted with NTFS, but I doubt it would work.

Read this for more info.

Hope this helps,
