I've started to use a ram disk too for the 'disk' cache (DataRam's free one) formatted with exFAT (4 or 8k allocation units). I also don't notice a huge speed improvement. I do want to try imDisk's version which is supposed to be direct IO and one of the fastest, but It's not as easy to configure as Dataram's.
I also notice that the hard drive light still blinks, which I thought it wasn't supposed to do that... So I'm not sure if it's ONLY accessing the RAMdrive or is something else that's downloading still going to the physical disk??? Should the hard-drive light still blink for accesses to a ramdrive? (i.e. Does it usually blink for accesses to ALL drives listed in 'my computer'?)
Historical note: I used to have a RAMdisk back when using my Commodore AMIGA 4000, since I had a whopping 256MB of ram! 8-O
Also interesting was that most RAMdisk programs were automatically able to survive a reboot, and be used to do a boot from them very early in the startup-sequence. Unfortunately, I don't think any Windows versions survive a reboot - only that copy-to-img and copy-from-img stuff. :-/ Well - at least I notice that process to be *VERY* quick on Windows, so that's good.
