Windows ReadyBoost

Is there a certain size or speed that my flash drive needs to be to take
advantage of ReadyBoost?

The following are requirements for USB flash devices enhanced for
ReadyBoost:
• USB flash drives themselves and the host controllers they are inserted
into must both use the USB 2.0 standard.
• USB flash drives must have at least 230 MB of free space.

Flash Performance
Flash storage devices must meet minimum performance requirements to support
ReadyBoost, including 2.5 MB/s throughput for random 4K reads and 1.75 MB/s
for random 512 K writes.
Higher performance requirements must be met for the device to be designated
as “enhanced for ReadyBoost�: 5 MB/s for random 4K reads and 3 MB/s for
randmon 512 K writes. Microsoft recommends that users use devices enhanced
for ReadyBoost

You may also want to have a look at Grant Gibson's 'ReadyBoost
Compatibility List' (http://www.grantgibson.co.uk/misc/readyboost/). I
can't say how up to date it is, but there are listings for over 1,000
flash drives on there.

Antec Nine Hundred / Core 2 Quad Q6600 / MSI P6N Diamond / CoolerMaster
RP Pro 1000 PSU / X-Fi 7.1 / 4x 1GB Corsair XMS2 PC-6400 / 2x MSI
NX8600GTS-OC / 150GB Raptor (system) / 2 x 500GB HDD (RAID 0) / 1x 300GB

I would like to add that for now, ready boost is only designed for 1 flash
drive up to 4gb. They plan to increase this after further testing and design
work.

Actually, it is limited to 4GB on a flash drive of arbitrary size. I use a
16GB Xporter.
