@spoof: I am using readycache for 3 month now and it works fine. I am using version 1.1 on a raid 1 disk configuration (dq57tm motherboard, win 7 x86).
I agree with you that it is very annoying to have to close a window every time the pc boots. From a developer prespective this is a design fail that professionals should not do.
There should be an option not to load the gui on startup.
I hope that this option will be included in the next version of the software and that the new software will be released soon. (Sandisk do you hear?)
Regarding version 1.1, send an email to sandisk and i bielieve they will give you a link to download it.
