is a software driver that emulates as fully as possible the low-level
functionality of a hard disk with system RAM. It speeds up applications because
RAM is much faster than mechanical hard disks for storing and retrieving data.
Applications that do a lot of reading and writing to storage, like database
queries, will show the most improvement. It can be configured to automatically
load a disk image at startup and save the image to disk at shutdown. This allows
it to function almost exactly like a hard disk; no data is lost when the power
is turned off.
