Modular mass storage system and method therefor
View Patent ↗A modular mass storage system and method that enables cableless mounting of ATA and/or similar high speed interface-based mass storage devices in a computer system. The system includes a printed circuit board, a system expansion slot interface on the printed circuit board and comprising power and data pins, a host bus controller on the printed circuit board and electrically connected to the system expansion slot interface, docking connectors connected with the host bus controller to receive power and exchange data therewith and adapted to electrically couple with industry-standard non-volatile memory devices without cabling therebetween, and features on the printed circuit board for securing the memory devices thereto once coupled to the docking connectors.
1. A mass storage system for a computer system, the mass storage system comprising:
a printed circuit board;
a system expansion slot interface on the printed circuit board and comprising power and data pins;
a host bus controller on the printed circuit board and electrically connected to the system expansion slot interface;
docking connectors adapted to electrically couple with industry-standard non-volatile memory devices without cabling therebetween, the docking connectors being connected with the host bus controller to receive power and exchange data therewith; and
means on the printed circuit board for securing the memory devices thereto once coupled to the docking connectors.
2. The mass storage system according to claim 1 , wherein the system expansion slot interface is a PCIe connector.
3. The mass storage system according to claim 2 , wherein the power and data pins conform to female SATA connectors, eSATA connectors, USB connectors, HDMI connectors, IEEE 1394 interface connectors or SO-DIMM sockets.
4. The mass storage system according to claim 1 , wherein the host bus controller is configured as a RAID controller.
5. The mass storage system according to claim 4 , wherein the host bus controller comprises onboard SDRAM, SRAM or pipeline burst SRAM used as data cache.
6. The mass storage system according to claim 4 , wherein the host bus controller comprises onboard logic capable of carrying out parity calculations for the RAID controller.
7. The mass storage system according to claim 1 , further comprising the memory devices secured to the printed circuit board and coupled to the docking connectors.
8. The mass storage system according to claim 7 , wherein the memory devices comprise at least one solid state drive.
9. The mass storage system according to claim 7 , wherein the memory devices comprise at least one hard disk drive.
10. The mass storage system according to claim 7 , wherein the memory devices comprise at least one USB 3.0 flash drive.
11. The mass storage system according to claim 7 , wherein the memory devices comprise at least one SO-DIMM.
12. The mass storage system according to claim 7 , wherein the memory devices comprise at least two drives chosen from the group consisting of solid state drives, hard disk drives, USB 3.0 flash drives, SO-DIMMs, HDMI drives, and IEEE 1394 interface drives.
13. The mass storage system according to claim 1 , wherein the mass storage system lacks any cables by which the memory devices receive power from and exchange data with a computer motherboard other than through the system expansion slot interface.
