Abstract
Methods for providing non-volatile solid-state mass storage media with different service levels for different types of data associated with different applications. The method includes partitioning the non-volatile solid-state mass storage media into at least first and second volumes, individually assigning different service levels to the first and second volumes based on a type of data to be stored in the first and second volumes and based on the first and second volumes having different data retention requirements and/or data reliability requirements, and then performing service maintenance on data stored within at least the first volume according to the service level of the first volume.
Claims26
A method of storing data on a non-volatile solid-state mass storage media functionally connected to a host system, the method comprising:
- partitioning the non-volatile solid-state mass storage media into at least first and second volumes;
- individually assigning different service levels to the first and second volumes based on a type of data to be stored in the first and second volumes and based on the first and second volumes having different data retention and data reliability requirements;
- and
- performing service maintenance on data stored within at least the first volume according to the service level of the first volume.
A non-volatile solid-state mass storage media comprising:
- non-volatile solid-state memory partitioned into a plurality of volumes, each volume of the plurality of volumes having an individually assigned service level based on a type of data to be stored in the volume, a data retention requirement, and a data reliability requirement, wherein
- at least one volume of the plurality of volumes having a different data retention and data reliability requirements than another volume of the plurality of volumes.
