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. For example, a modular drive bay maintains a pointer to a memory address in the removable drive memory cannot write data to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable drive. As such, once data is written to the removable drive, the data cannot be overwritten although the removable drive employs random access memory.
