For writing I would have assumed it already did use ram to cache. Maybe not so much for later rereading.
I forget exactly what but I could have sworn there was a command for preloading a file into memory.

yep. In fact, if you've recently worked with it, the OS doesn't have to reload it from disk. And, depending upon how you tune the kernel you could make it to where the OS practically only ever flushes the disk writes upon reboot or exceeding physical memory. until that point all work with the file is being performed within in the memory space.
