Problem configuring readyboost to recognise an 'approved' Transcend 4GB SD card

I am trying to use Vista's 'ReadyBoost' facility to speed up this disappointingly slow laptop.  On the advice of Orcalogic I have installed a 4GB Transcend SD card (150x speed) which they say is compatible with Vista ReadyBoost.  However, when I insert the card into the built-in slot in the laptop and test it for ReadyBoost compatability it reports back that "This device does not have the required performance characteristics" to enable it to speed up the system.

Please can anyone suggest a fix ?  What are the ReadyBoost "performance characteristics ? and does the SD card need formatting in a particular way etc.  All help appreciated.  Thanks, Will

Those 2 QA should tell you what to look for
Q: What perf do you need on your device?
A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes

Q: My device says 12MB/sec (or 133x or something else) on the package but windows says that it isn't fast enough to use as a ReadyBoost device... why?
A: Two possible reasons:

   1. The numbers measure sequential performance and we measure random. We've seen devices that have great sequential perf, but horrible random
   2. The performance isn't consistantly fast across the entire device. Some devices have 128M of lightning fast flash and the rest of the device is really slow. This is fine for some applications but not ReadyBoost.

Thanks for this.  I also found a link to a simple registry edit allowing you to force values for read and write into the registry in order to by-pass the Microsoft ReadyBoost read / write performance requirements. This did enable me to use the SD card with ReadyBoost but I've not yet properley tested whether this has resulted in a significant improvement in performance relative to the system without ReadyBoost. Thanks again anyway for the accurate information supplied anyway !
