Data storage apparatus with a HDD and a removable solid state device

摘要

According to an example, a data storage apparatus may include a non-volatile primary storage medium, a coupling interface to removably receive a non-volatile solid state device, a communication line connected to the non-volatile primary storage medium and the coupling interface, and a storage controller connected to the communication line. The storage controller may determine a memory type of the non-volatile solid state device, cache a first type of data in the non-volatile solid state device in response to a determination that the non-volatile to solid state device is of a first memory type, and cache a second type of data in the non-volatile solid state device in response to a determination that the non-volatile solid state device is of a second memory type, in which the second type of data differs from the first type of data.

1. A data storage apparatus comprising:
a non-volatile primary storage medium; a plurality of coupling interfaces to removably receive a plurality of non-volatile solid state devices of differing memory types operable as caches; a communication line functionally connected to the non-volatile primary storage medium and the plurality of coupling interfaces; and a storage controller connected to the communication line to control operations of the non-volatile primary storage medium and the plurality of non-volatile solid state devices, wherein the storage controller is to determine memory types of the plurality of non-volatile solid state devices and cache data in the plurality of non-volatile solid state devices based upon a priority of the data and the memory types of the plurality of non-volatile solid state devices to control caching operations of the non-volatile primary storage medium.
