Abstract: A storage device connected to an information processing apparatus includes processing circuitry configured to perform data transfer with the information processing apparatus at any one of a plurality of predetermined data transfer rates. The processing circuitry is further configured to perform the data transfer with the information processing apparatus at a data transfer rate lower than a data transfer rate of an upper limit among the plurality of data transfer rates, without performing the data transfer at the data transfer rate of the upper limit.

Abstract: The process for producing a frozen fish meat for producing a frozen red fish meat, includes: a freezing step of cooling a red fish meat and freezing a whole of the red fish meat including a superficial layer and an inner core part; a superficial layer thawing step of heating the red fish meat frozen in the freezing step from an outer side to thaw the superficial layer of the red fish meat; and a refreezing step of stopping heating the red fish meat after the superficial layer is thawed in the superficial layer thawing step, and then refreezing the superficial layer of the red fish meat at a lower freezing speed than a freezing speed in the freezing step.
