Many USB 2.0 memory devices are fast enough to use for
ReadyBoost, but others are not, including some that claim to be very fast. The problem
is that ReadyBoost requires all the memory in the memory device to be consistently
fast, while some devices use a special high-speed memory gateway to get better performance
out of a larger bank of slower memory. Such an arrangement doesn??™t work
for ReadyBoost.
Some companies market memory devices as being suitable for ReadyBoost. With
such devices, you??™re on safe ground??”although the prices tend to be higher than for
regular memory devices. If a device isn??™t marked as being suitable for ReadyBoost,
make sure all its memory can provide at least 1.75 megabytes per second (Mbps) for
512KB random writes, and 2.5 Mbps for 4KB random reads. Finding out this information
usually involves reading the manufacturer??™s specification sheet.
If you already have a USB 2.0 memory stick, it??™ll cost you nothing to find out
whether it works for ReadyBoost.
Step 4: Configure ReadyBoost on Your PC
Once you??™ve chosen your device, configure ReadyBoost on your PC. Follow these steps:
Plug the drive into a USB port on your PC. (You can also use a USB hub, but
plugging it directly into a port usually gives more consistent results.) Windows
displays the AutoPlay dialog box for the drive.
