1. A storage device enclosure system comprising:
two hard disk drives (HDDs);
a form factor compatible connector, the form factor compatible connector attached to the two HDDs and configured to connect the two HDDs to an external computing system; and
a controller, the controller located on the form factor compatible connector and configured to perform redundant array of independent disks (RAID) functions on data from the external computing system via a SATA port multiplier onto the two HDDs.
2. The storage device enclosure system of claim 1 , wherein the form factor compatible connector is compatible with an approximately 2.5″ form factor.
3. The storage device enclosure system of claim 1 , wherein the storage device enclosure system is configured for an approximately 10-15 mm personal computer slot.
4. The storage device enclosure system of claim 1 , wherein the two HDDs communicate with each other via the customized RAID controller using SATA commands.
5. The storage device enclosure system of claim 1 , wherein at least one of the two HDDs is a solid state hybrid drive.
6. The storage device enclosure system of claim 1 , furthering comprising a shared dongle on the form factor compatible connector to connect the two HDDs to the external computing system.
7. A storage device enclosure system comprising:
two hard disk drives (HDDs), wherein at least one of the two HDDs is a solid state hybrid drive;
a form factor compatible connector, the form factor compatible connector attached to the two HDDs and configured to connect the two HDDs to an external computing system; and
a customized controller, the customized controller located on the form factor compatible connector and configured to selectively perform operations on one or both of the two HDDs via a SATA port multiplier.
8. The storage device enclosure system of claim 7 , customized redundant array of independent disks (RAID) controller configured to perform data mirroring write operations on data from the external computing system via the SATA multiplier to the two HDDs.
9. The storage device enclosure system of claim 8 , wherein the two HDDs communicate with each other via the customized RAID controller using SATA commands.
10. The storage device enclosure system of claim 9 , wherein the customized RAID controller is further configured to perform staggered spin-up operations based on a determination that the external computing system is performing a power-on sequence.
11. The storage device enclosure system of claim 10 , wherein the customized RAID controller is further configured to perform spin-down operations on at least one of the two HDDs based on a determination that the external computing system has entered a lower power state.
12. The storage device enclosure system of claim 11 , wherein the customized RAID controller is further configured to perform striping read operations on data from the external computing system via the port multiplier to the two HDDs reading approximately half the data from each HDD in parallel for better performance.
13. A method comprising:
mirroring data from an external host computer to two hard disk drives (HDDs) in a storage device enclosure via a form factor compatible connector attached to the two HDDs, the form factor compatible connector including a controller and a SATA port multiplier and configured to facilitate communication via SATA commands between the two HDDs.
14. The method of claim 13 , further comprising selectively performing operations on one of the two HDDs with a customized redundant array of independent disks (RAID) controller.
15. The method of claim 14 , further comprising retrieving data from one of the HDDs if the other HDD exhibits slow read performance.
16. The method of claim 14 , further comprising retrieving data from one of the HDDs if the other HDD fails.
17. The method of claim 16 , further comprising performing a staggered spin operation with the customized RAID controller during data retrieval.
18. The method of claim 17 , wherein at least one of the HDDs is a solid state hybrid drive.
19. The method of claim 18 , further comprising steering data read operations to the solid state hybrid drive.
