Distributed data storage system with offline optimization

A method comprising:

• connecting a customization module to distributed data storage system, the distributed data storage system comprising at least one host connected to a first data storage device and a second data storage device via a network controller;
• disconnect the first data storage device from the host and second data storage device;
• assessing a data access operation of the first data storage device with the customization module;
• generating an optimization strategy with the customization module based on the assessed data access operation;
• implementing the optimization strategy in the first data storage device to alter at least one data access parameter of the first data storage device;
• connecting the first data storage device to the host and second data storage device;
• and
• executing at least one data access to the first data storage device with the altered at least one data access parameter.
