Abstract: According to one embodiment, a storage device includes a non-volatile memory and a control unit that is electrically connected to the non-volatile memory and that is configured to control the non-volatile memory. The control unit is configured to manage a plurality of management areas obtained by logically partitioning storage area of the non-volatile memory, when a write request is received that includes data for which a valid term has been set, determine, based on the valid term, a first management area from among the management areas, write the data included in the write request to the determined first management area, and when the data written to the first management area is erased, collectively erase all data written in the first management area which includes the data.

Abstract: The present invention relates to an improvement in spectral analysis in spectrometry, particularly in a technique of spectral analysis by spectral classification at high speed. A spectral analysis device 10 comprises: a measurement unit 20 that measures a sample spectrum of a target sample 30; and an analysis unit 40 that analyses the sample spectrum, and analyses a compound contained in the target sample 30, wherein the analysis unit has a library that is processed with an arithmetic processing in advance, the library has a plurality of compound groups to which the compound is classified, and the analysis unit further comprises an analysis display part 42, the analysis display part 42 displays, in real time, the compound group to which the compound belongs during analysis of the sample spectrum as the analysis progress or analysis result.
