Information processing device, storage device, and method of calculating evaluation value of data storage location

A storage device, comprising:

• a non-volatile memory;
• and
• a controller connected to the non-volatile memory and configured to:
• refer to address conversion data which has a plurality of logical addresses associated with a plurality of physical addresses in the storage device when an evaluation command and the plurality of logical addresses of an evaluation target is received from an external device;
• convert the plurality of logical addresses of the evaluation target into the corresponding plurality of physical addresses of the evaluation target by referring to the address conversion data;
• and
• calculate an evaluation value indicating a parallel reading performance for the plurality of physical addresses of the evaluation target using an internal parameter specifying a number of areas of the storage device readable in parallel.

A method of calculating an evaluation value of a data storage location in a computer system which includes a storage device having a non-volatile memory and an information processing device connected to the storage device, the method comprising:

• causing one of the storage device or the information processing device to refer to stored address conversion data which has a plurality of logical addresses associated with a plurality of physical addresses;
• converting a plurality of logical addresses of an evaluation target into a corresponding plurality of physical addresses of the evaluation target by referring to the stored address conversion data;
• and
• causing the one of the storage device or the information processing device to calculate an evaluation value indicating a parallel reading performance for the plurality of physical addresses of the evaluation target using a parameter specifying a number of areas of the storage device readable in parallel.
