System and method for selecting a write unit size for a block storage device

A method for selecting a data unit size for accessing a storage media, the method comprising:

• preconditioning the block storage device by:
• emptying the block storage device;
• and
• writing data to the block storage device to fill the block storage device above a predetermined level;
• performing a plurality of series of write and read operations to the storage media, each series having a single data unit size over time that is different from the other series of write and read operations;
• measuring performance metrics of the series of write and read operations;
• and
• accessing the storage media using the data unit size having the best performance metrics.

A system for monitoring of movement of data in a computer network, the system comprising:

• a memory;
• and
• a processor configured to:
• perform preconditioning the block storage device by:
• emptying the block storage device;
• and
• writing data to the block storage device to fill the block storage device above a predetermined level;
• perform a plurality of sequences of I/O operations to the block storage device, each sequence having a write unit size from a plurality of write unit sizes;
• collect performance metrics of the sequences of I/O operations;
• and
• select the write unit size for the block storage device from the plurality of write unit sizes based on the performance metrics.
