Claims

1. A data storage unit having a source of electronic communication and a source of electronic power, the data storage unit comprising: a frame defining a storage unit interior space,at least one media blade accommodating a plurality of storage elements;the plurality of storage elements receiving at least electronic communication and electronic power from said electronic communication source and said electronic power source via said media blade;the media blade adapted for being at least partially moved into and out from the interior space without interruption of the communication and power.

2. The storage unit of claim 1 further comprising a latch mechanism to prevent the media blade from totally being removed from the unit interior space.

3. The storage unit of claim 1 wherein said media blade is adapted to be received by an accommodating opening in the frame.

4. The storage unit of claim 3 wherein the storage unit is adapted to accommodate a plurality of media blades.

5. The storage unit of claim 1 wherein the media blade is partially moved between a retracted position wherein substantially all of the storage elements are within the interior space and an extended position wherein substantially all of the storage elements are external to the interior space, the media blade remains supported by data storage unit while the media blade is partially moved.

6. The storage unit of claim 5 wherein the media blade is adapted to be supported by the storage unit when fully in the extended position.

7. The storage unit of claim 1 wherein the media blade comprises a base for supporting a base board, the communication and the power can be transmitted via the base board.

8. The storage unit of claim 7 wherein the base can accommodate a plurality of storage element power and communication connectors for the storage elements.

9. The storage unit of claim 8 wherein the storage element power and communication connectors are Serial Attached Small Computer System Interface connectors.

10. The storage unit of claim 1 wherein the power and the communication are provided to the media blade by a power and communication linking device selected from one of the group consisting of: a ribbon cable, at least one independent conductive wire, a flex cable, at least one group of conductive wires.

11. The storage system of claim 10 wherein the power and communication linking device comprises a tangling prevention device.

12. A method of operating a data storage unit wherein the data storage unit comprises a frame that defines an interior space, the method comprising the steps of: receiving a first data package from a host;storing the first data package on at least one of a plurality of data storage elements that are supported by a first media blade;moving the first media blade along a guided pathway adapted for the first media blade from a first position that is substantially within the interior space to a second position that is less than substantially within the interior space without interrupting the storing.

13. The method of claim 12 wherein the first position is when at least all of the storage elements are within the interior space.

14. The method of claim 13 wherein the second position is when all of the storage elements are out side of the interior space.
