I should write a book!

I got the USB info from http://www.usb.org/developers/packaging about the data rates for High Speed USB transfer, which is up to x40. That still does not indicate whether that memory is standard or flash. I have many Jump drives which are x10 to x20 and they will now work with ReadyBoost. 

 

I got more info from Crucial about USB Flash Drives http://www.crucial.com/store/listmfgr.asp?cat=drives+storage that indicate the reads are twice as fast as the writes. 13 meg read x80 and and 25 meg x160 writes for Very High Speed USB 2 Flash. So, there is a big difference between USB speeds and x rates for all USB 2 memory drives. 

 

Microsoft says USB Flash Memory for ReadyBoost. So, that would mean a very High Speed USB 2 Flash drive or a Flash Card Reader that can read Flash memory, which is usually x40 and higher?   In fact I have several x133 2.2 gig microdrives with a Card Reader, and they will work with ReadyBoost. I also have a friend who has x300 flash memory, so the rates can go up pretty high, but are they necessary?  

 

If USB High Speed 2 can only transfer at a rate of x40, I am still in the dark as to why ReadyBoost needs anything higher?

 

Microsoft KB’s also state that many manufacturers use a small cached Flash memory at high level and then the remaining memory at low level, which is not compatible with ReadyBoost. They also indicate Kingston memory meets the specs.

 

Well I won’t know how all of this will effect Vue until they ship the Retail. Man my teeth are getting short!!!
