Enable ReadyBoost on a second internal HDD?

Enable ReadyBoost on a second internal HDD?

I have two SATA HDDs in my desktop PC (one for daily activity, one for storage and backup). I can finely use ReadyBoost with pendrives, but I wonder, Is there a way I could use my underutilized second HDD to participate in the cacheing mechanism (same concept as having two CPU cores crunch things in parallel: have two HDDs fetch data in parallel)? Clearly speaking: I want to enable ReadyBoost on my separate D: drive.

"ReadyBoost is designed to take advantage of the almost non-existant latency of most flash drives to get small amounts of data into memory quickly. A modern hard drive will still easily out transfer most usb flash drives (50-100MB/s vs. 10-20MB/s) after just a few hundred milliseconds on average.

There really isn't a good way to enable your suggested scenario, or a performance reason to consider it. You would be better off using your second hard drive in a RAID1 configuration (some controllers support parallel reading), or possibly offloading programs/data that won't have to contend for I/O with the boot drive. You would be amazed at the near constant amount of small I/O that happens on the boot drive."

"I think that the memory card reader interface is not as fast as the SATA interface. I thought that the USB2.0 data transfer rate is 400mbps where as the SATA3 transfer rate is 600mbps. In burst, i get transfer rates up to 68mb per second SATA to SATA where as I get only 20mb per second tops from the memory card.

If you are trying to impliment ready boost, make sure you are using a USB3.0 interface card reader (must be USB3.0 on both motherboard and card reader) AND your memory card must be a high speed one too."
