Psuedo Hybrid Drive
I am planning a Vista64 Home Premium build and have a few questions about
increasing the performance of the OS. Due to the lack of availability of 3.5" Hybrid Desktop Hard Drives I am looking at the ReadyBoost feature of Vista. Obviously a Hybrid drive would cache data to allow better use of the SATA bus by bursting the data at high speed. I am trying to figure out if I can substitue another media for this funciton. From what I have read ReadyBoost is a mechanism to move or distribute the pagefile/virtual memory to a secondary storage device. I found a vague article "http://windowshelp.microsoft.com/Windows/en-US/Help/12428141-2e4c-43ab-8dd2-a6ed6e3b87761033.mspx" which references removable storage devices and mentions USB drives several times. It also mentioned setting the ReadyBoost size to 1.5 times the physical ram (typical windows managed pagefile size), which I think it is moving the pagefile. My questions a 1. Is ReadyBoost limited to USB drives? Could a seconday drive in the computer be used for this feature, like mapping the pagefile to another drive to free the OS drive from the I/O load. More importantly can I use my SATA RAM drive which has 0.1ms seek time and 152 MB/sec transfer rate across the drive space? 2. Does ReadyBoost provide the same benefit as a Hybrid drive in terms of boot up performance. 3. Can anyone validate my belief that ReadyBoost is just a pagefile mounted to another drive to releive the main drive of the I/O load 4. At what point would allocating space to an external storage device be un-beneficial? If it is just a pagefile, then I know the answer. A better understanding of the two mechanisms will help me decide what hardware to put in my upcoming computer. Thank You in Advance!

Psuedo Hybrid Drive
As it happens, after I made my original post I continued to do research. I
came a across a document at http://download.microsoft.com/downlo.../perfaccel.doc which does explain in more detail how SuperFetch, ReadyBoost, and ReadyBoost work. This document answered most of my questions, and I guess I could always move the pagefile to my ram drive.
