I have several SSDs in my system and several hard drives too. I boot from one of the SSDs and would really like to use some of the spare space on one of my other SSDs to cache the hard drives (or at least one of the hard drives).
I know that this wasn't possible at the time I wrote my answer to that question (you could only SRT cache the boot drive), but is it still true? A quick search didn't find anything useful, most articles appear to refer to the version of SRT released at the time of the Z68 chipset.
If it is possible to cache an arbitrary hard drive, what are the requirements? Do you just need to update SRT, or does this functionality need a more recent chipset or ICH? Is it possible to set up multiple cache sets (presumably one cache partition per real partition or drive cached). Could you cache several hard drives using several partitions on a single SSD (so give each of 4 HDs a 64GB partition on a single 256GB SSD etc.)?
