View Edit Delete	2380.2.01	The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available data storage systems. Accordingly, the present invention has been developed to provide an apparatus, system, and method for managing data that overcome many or all of the above-discussed shortcomings in the art.	10	Added by DJM 3 2021	3/16/21, 12:00 AM
View Edit Delete	2380.2.01	From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method that manages data using a data pipeline within a solid-state storage device. Beneficially, such an apparatus, system, and method would allow each stored data segment to be indexed and stored with different requirements, such as different compression requirements, different encryption keys, etc.	9	Added by DJM 3 2021	3/16/21, 12:00 AM
View Edit Delete	2380.2.01	Traditional write-in-place and other data handling techniques associated data management techniques associated with write-in-place and other traditional storage prevent solid-state storage from achieving much higher possible performance.	8	Added by DJM 3 2021	3/16/21, 12:00 AM
View Edit Delete	2380.2.01	Using write-in-place for solid-state storage can lead to premature failure of the solid-state storage because typically each cell in a solid-state storage device can only be written to a certain number of times before the cell begins to fail. Write-in-place typically does not evenly distribute writing data over the solid-state storage so some regions or addresses are used much more than other areas. This overuse of some areas can lead to premature failure of all or a portion of a solid-state storage device.	7	Added by DJM 3 2021	3/16/21, 12:00 AM
View Edit Delete	2380.2.01	Using write-in-place for solid-state storage can be inefficient because typically writing data often takes much longer than reading data. For flash memory, which is a type of solid-state storage, changing a bit from a “zero” state (“zero”) to a “one” state (“one”) usually takes longer than changing a bit from a one to a zero. This is the case for typical flash memory that uses capacitors as cells where a zero equates to a discharged capacitor in a cell and a one equates to a charged capacitor in a cell. Typically, charging a capacitor takes longer than discharging a capacitor.	6	Added by DJM 3 2021	3/16/21, 12:00 AM
View Edit Delete	2380.2.01	Data storage devices are typically write-in-place in that data accessed at a particular location can be modified and then put back in the same location. A file or object may be divided and placed piecemeal in the data storage device in various locations where no data is stored or where data is marked invalid. While this method works well for devices such as a hard disk drive (“HDD”), using write-in-place for solid-state storage can be inefficient and can cause premature failure.	5	Added by DJM 3 2021	3/16/21, 12:00 AM
