ReadyBoost (Win 7) - Has anybody seen any Speed Up? | Gen-Tech | Forums

I haven't tried ReadyBoost (still on XP), but from [my] memory of what I've read/heard, the speed of your USB Flash Drive/Flash Memory Cards is the most likely cause of a problem.

Not all USB Drives are the same speed, and for ReadyBoost to work you need a quick one.

hmmm …..

from reading http://technet.microsoft.com/en-us/magazine/ff356869.aspx

it could be that your computer may not benefit from ReadyBoost?

(I would still recommend testing some other USB Flash Drives/Flash Memory Cards to see if they provide a benefit)

ReadyBoost provides the most significant performance improvement under the following circumstances:

* The computer has a slow hard disk drive. Computers with a primary hard disk Windows Experience Index (WEI) subscore lower than 4.0 will see the most significant improvements.
* The flash storage provides fast, random, non-sequential reads. Sequential read speed is less important.
* The flash storage is connected by a fast bus. Typically, USB memory card readers are not sufficiently fast. However, connecting flash memory to an internal memory card reader might provide sufficient performance.

Computers with fast hard disks (such as 7,200- or 10,000-RPM disks) might realize minimal performance gains because of the already high disk I/O.

maybe you could run Windows Experience Index and see what it rates your hard drive as?

and to test your USB / Flash memory to see if it "provides fast, random, non-sequential reads", something like Crystal Disk Mark (http://crystalmark.info/software/CrystalDiskMark/index-e.html) is what you're after.

good luck :-)
