What Is the Typical Amount of RAM Required for RAM-based EWF?
Submitted by: Nandini Shenoy For EWF RAM-based overlays, writes made to your EWF-protected volume are redirected to RAM. The changes that are made to your protected volume are not permanent and are lost when the computer restarts. You can retain the writes that were made to a volume when you commit your EWF overlay. The amount of RAM that is required for RAM-based EWF depends on the configuration of the run-time image. If you have applications in the run-time image that are making a lot of writes to your protected volume, RAM consumption is high. Minimally, an EWF overlay requires only a few megabytes of RAM. The maximum size of an EWF RAM overlay is the size of the protected volume in addition to a small percent for overhead (less than one percent). The EWF RAM usage reaches maximum size if all sectors on the protected volume are overwritten in a single boot. For best results, monitor the writes of your applications and configure your runtime to avoid all unnecessary writes. Keep in m
