Abstract
Embodiments provide systems and methods for maintaining immutable data in an archiving system using random access memory. To ensure data is immutable, novel pointers are maintained in the hardware/firmware of the drive ports and on the removable disk drives. For example, a hardware/firmware in a modular drive bay maintains a pointer to a memory address in the removable disk drive memory that cannot write to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable disk drive. As such, once data is written to the removable disk drive, the data cannot be overwritten although the removable disk drive employs random access memory.
