182GB/s, for up to 32MB of data. It's an interesting study in misusing the tech, but it's ultimately a bit meaningless.
What we really need is for someone to modify the ramdisk driver to appear as usb storage and make it so it runs under Vista, so we can use it for ReadyBoost.
There's a list of 802.3 standards at https://en.m.wikipedia.org/wiki/IEEE_802.3, if anyone's curious to see the development and future of ethernet. Some of the numbers involved are absolutely crazy.
Curious to ask what you're using this for.
Regarding buying raw cards, you'd want to buy from an industrial-facing outlet. Going closer to source is your best bet, so, buying from a reseller on Aliexpress or the like. You'll probably need to buy in volume though. The easier solution is probably just to use Diskpart to clean the disk, which takes seconds.
32MB is what they tested on the article.
To clarify a little on what's happening here, they're not using the v-cache as a memory space and making the volume there as you might create a partition on a conventional disk drive, but rather, they're accessing the ramdisk in such a way as to trick the system into keeping that it in cache. It's almost completely impractical in real terms, but it's a fun way to exploit the cache algorithm to get some silly numbers out of it.
