Time shift buffer via flash memory

A method comprising:

• receiving, by one or more computing devices, content from a storage medium for playback, wherein the received content comprises a stored portion of a transport stream;
• causing, by the one or more computing devices, playback of the received content;
• determining, by the one or more computing devices, a playback position of the received content relative to a live position of the transport stream;
• and
• storing, by the one or more computing devices, at least a first portion of the transport stream to a first partition of the storage medium and at least a second portion of the transport stream to a second partition of the storage medium in response to a determination that the determined playback position of the received content satisfies a threshold proximity to the live position.

• responsive to a determination that the determined playback position of the received content satisfies a threshold proximity to the live position, storing, by the one or more computing devices, at least a first portion of the transport stream to a first portion of a data block having a finite block size and at least a second portion of the transport stream to a second portion of the data block, wherein the second portion of the data block is configured to be read prior to the first portion of the data block.
