Partitioning in Regards to ReadyBoost

Community,

Before I begin, I'd like to make one thing explicitly clear: this question is going to ask if it's possible to do a particularly frivolous, if not expensive project, in theory. I do not want to see answers that read "Oh, that wouldn't make a difference even if it worked," or, "that's dumb, just leave it alone." I really, really, really hate answers that, rather than answer the question, simply give the OP a thoughtlessly written, if not arrogantly toned, statement declaring why they feel that the project doesn't deserve a proper answer, but rather a (financially) biased opinion. I'm well aware that all gains, if any, will be minimal at best, and just want to know if it will work, not if it's practical. Now, with that out of the way...

I've recently grown interested in Microsoft's ReadyBoost for Windows 7; from what I understand in the Wikipedia article discussing ReadyBoost in all its forms, the Windows 7 version can support up to 8 devices ranging from 256mb to 32gb each (for a possible maximum of 256gb in an array similar to a RAID 0 set-up). I'd like to try reaching this maximum, but my laptop only has three (3) USB ports and a single SD card slot.

So here's my plan to reach that limit, as wanton as it is: grabbing a single 256gb SD card and partitioning it into 8 separate drives.

And here's my question: Will Windows ReadyBoost recognize each partition as a separate device? And if it does, will it be able to use all eight partitions simultaneously? And, if it can, how would the Read/Write speed of each partition be affected if the device were a Class 10 card?

As mentioned ablove, I'm fully aware of the impracticality of implementing this wanton amount of cache into my already speedy system; I'd just like to know, in theory, could this work and work well?

And for those of you even remotely interested in my laptop's baseline specifications, here they are:
HP 4-1030us
i5-3317u @ 1.7ghz (2.6ghz w/ Turbo Boost)
2x4gb Corsair RAM (1600mhz, 9-9-9-24, Dual-Channel) (self-upgrade)
500gb Hitachi 5400 RPM drive w/ 32gb mSata chip (RAID 0)
Intel HD 4000 Graphics (350mhz idle, 1050mhz w/ Turbo Boost)

Regards,
A.J.
