RAM disks can be dynamically created and destroyed after the device boots, or remain static after creation by the First Boot Agent. A RAM disk’s content (image) can be saved to a storage device (including a network drive) automatically at device shutdown, or by command at any time. Disk size is limited only by available memory. RAM disks can be created with or without a file system, and support FAT, FAT32 and NTFS, according to their size.

The RAM disks created by RamDisk Plus Embedded are allocated from physical memory, not the system’s paged or non-paged pools. Memory is mapped and locked into virtual address space only when required for read or write operations. These design features help keep the disk’s burden on operating system resources to a minimum.

In a static environment (no disk creation or destruction after FBA), a RAM disk can be implemented with a footprint of less than 130 KB. The maximum, full-functionality, footprint of the registered binaries is less than 350 KB.

The RamDisk Plus Embedded package includes a full set of components and their associated repository which can be used as-is or modified by Component Designer. The included components support a wide range of possible configurations, including read-only storage environments.
