Abstract
A data storage assembly for cold storage. The data storage assembly includes a circuit board and a plurality of hard disk assemblies (HDA). Each HDA includes a platter and a head assembly to read and write data on the platter. The circuit board includes a processor and a memory. The processor acts as a hard disk controller for the plurality of HDAs and controls the platters. The processor further manages which HDAs are active at a time and the memory is shared by the plurality of HDAs.

A data storage assembly comprising:
- a circuit board comprising:
- a processor;
- a memory;
- and
- a read channel;
- and
- a plurality of hard disk assemblies (HDAs), each HDA comprising:
- a platter configured to store data;
