Full Description:
BACKGROUND OF THE INVENTION  
     Field of the Invention  
       [0001]     The invention lies in the computer technology field. More specifically, the invention relates to a storage device for the computer industry.  
         [0002]     The personal computer revolution of the early 1980&#39;s created a need for data storage devices with the ability to read/write and modify data as needed by the computer applications. Before the personal computer revolution, data was saved on magnetic ring units that occupied a large space and had a limited capacity and very low performance levels.  
         [0003]     With the personal computer revolution, the market demanded a larger storage capacity and more compact sized storage device that could be connected to the computer. The first Personal Computer (PC) that was produced by IBM (International Business Machine) in the early 1980&#39;s supported a 5.25″ floppy disk with a limited storage capacity and very poor performance. At the time it was the height of technology.  
         [0004]     With the release of the IBM XT, the first Hard File Device—a ST506 5.25″ 10 MB Disk—was introduced in the personal computer market. As software applications began to require more and more storage space and a faster data transfer rate between the computer and the storage device, the computer industry faced a challenge of supplying faster and higher capacity storage devices.  
         [0005]     The computer industry has introduced various types of storage devices such as hard disks, tape drives, optical disks, CD ROMs, DVD players, removable media (floppy drives, Zip drive) with various types of interface formats (ST506, ESDI, IDE, EIDE, ATA, SATA, SCSI, SAS) with the goal of being faster, higher-capacity and more affordable to the user.  
         [0006]     Over time, the computer industry settled on the two common mostly used interfaces: SCSI and ATA/ATAPI. The SCSI interface (Small Computer System Interface) has long been considered the highest performance and highest capacity drive interface. For this reason, SCSI disks are used for high performance systems such as servers and workstations. The ATA/ATAPI (Advance Technology Attachment Protocol Interface) interface is a less expensive alternative to the SCSI interface, with a lower performance levels adequate for the personal desktop computer market as well as other moderately sized computer systems (POS, medical equipment, web server, etc.). Over time, the ATA/ATAPI storage devices interface has improved to close the gap in performance and capacity with the SCSI interface storage devices.  
         [0007]     The early SCSI devices were supported by 50 pin connectors and the ATA/ATAPI by 40 pin connectors. Both storage types are connected via a flat cable to the host computer system. This type of connection is known as parallel connection. The flat parallel cable connection limits the use of these storage devices to internal use due to the limited recommended cable lengths and the complexity of delivering several signals at once.  
         [0008]     To overcome some of the problems caused by the flat cable, (noise, cable length, space, speed of data transfer, air flow limitation, etc.) the computer industry recently introduced the SATA (Serial Advanced Technology Attachment) and the SAS (Serial Attachment SCSI), two new interface formats that transfer data through serial connection but follow the same protocols required by ATA/ATAPI and SCSI interfaces respectively. The protocol compatibility is necessary to allow the existing operating systems and software applications to be compatible with the new storage devices without the need for any software modification. This compatibility allowed the industry to quickly and easily adapt to the new serial interface technologies.  
         [0009]     The desired sharing of data and the increase of a local network at work place and homes started a new category of external devices called Network Attached Storage (NAS). A network-attached storage (NAS) device is dedicated to nothing more than file sharing. A NAS device does not need to be located within the server but can exist anywhere in a LAN.  
         [0010]     It is a safe prediction that networks will always be short of storage capacity. As a clients&#39; storage grow, so do the volumes of data they want to store locally and share on a central server. For a small or medium size business adding storage to a server to keep user happy is a tiresome and often-time consuming business. Far easier, is to buy a network attached storage (NAS) appliance that simply plugs into the network with a minimum setting. In fact this easy of use combined with the dropping cost of storage means that NAS has grown to become a very popular hardware category.  
         [0011]     In today&#39;s market, one of the most widely used connections to a network is via the so-called RJ-45 connector. The protocol communication of the attached device can be any given protocol and it should not be used as a limitation to this invention.  
         [0012]     In order to use an ATA/ATAPI/SCSI or any other storage device as a NAS device, a bridge between the storage device and the network port (RJ-45) is needed. The industry quickly filled this need by developing hardware to serve as the bridge to convert the storage devices signals interface to a RJ-45 connector with the desired protocol. There is a tremendous market for NAS devices that connect to the network in this fashion.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0033]     Referring now to the figures of the drawing in detail,  FIG. 1  shows a bare storage device  101  without any electronics attached to it. The storage device described in this figure can be a Heads Disk Assembly (HDA) or and type of removable storage device such as a CD-ROM, DVD, tape drive, etc. The figure shows an HDA device that includes magnetic platters, heads and a servo motor protected by a vacuum sealed package to avoid damage from dust and to achieve high speed rotation of the platters. The faster the rotation of the platters, the faster data can be transferred between the HDA, the control unit and the host computer.  
         [0034]      FIG. 2  shows a PCB with electronics forming the Control Unit  102  that includes all components needed to control the storage device  101  for the purpose of transferring data in and out of the storage device  101 . The control unit  102  also includes a 40 pin (male) interface connector  103  (Parallel ATA/ATAPI) that is connected via a 40 pin cable  124  (shown at  FIG. 8 ) to the host computer, and a power connector  105  for receiving the power needed to power the control unit  102  and the storage device  101 . The control unit  102  can be with any type of interface connection.  FIG. 2  shows the 40 pin signal interface connection  103  without any intention of limitation on the storage device interface.  
         [0035]      FIG. 3  shows a storage device  101  integrated with a control unit  102  forming a parallel ATA/ATAPI storage device  106  with a 40 pin signal interface connector  103  and the legacy power connector  105 .  
         [0036]      FIG. 4  shows a storage device  101  integrated with a control unit  102  forming a serial ATA/ATAPI storage device  109  with a serial ATA interface connectors  107 ,  108  that includes the data and power signals and the legacy power connector  105 . The reason for this serial ATA/ATAPI storage device  109  having both types of power connectors is for compatibility purposes only. Only one of the power connectors is actually required for operation at any given time.  
         [0037]      FIG. 5  shows a RJ-45 Modular Jack Female  110  and RJ-45 Modular Jack Male  112  connected to a twisted-pair cable  111 .

         [0048]      FIG. 8  shows a complete assembly of a parallel ATA  106  and an Ethernet bridge  121  to form a storage device to be connected to a computer or computer network via a RJ-45 connector  122 . This Figure also shows a twisted-pair cable  111  that connects at one end to the RJ-45 connector  122  on the Ethernet bridge  121  and at the other end to the computer network  127  to allow data transfer between the parallel ATA Disk  106  and the network computer system.  
         [0049]      FIG. 9  shows the invention that includes a storage device  101  with a control unit  102  that integrates a RJ-45 modular jack female connector  122  forming a native RJ-45 storage device  128 . The native RJ-45 storage device  128  will generate data in any protocol that use the RJ-45 connector as a mean to transmit/receive data via the twisted-pair and the RJ-45 connectors.  
         [0050]      FIG. 10  shows an external storage device in an external enclosure  129  that contains the invention: a native storage device with RJ-45 connector  128  that is connected to the network computer  127  via a twisted-pair cable  111 .  
         [0051]     I consider herein two distinct implementations of the novel configuration, namely: 
        The “bridge component” and the RJ-45 connectors may be integrated on the storage device control unit; or     a new set of components can include, without a limitation, an ASIC (application specific IC) device to be configured and/or assembled to support the storage device heads, the motor and data transfer via a RJ-45 connector, thereby supporting any desired transfer protocol.        
 
         [0054]     The term “native” as used herein should be understood to include these implementations.  
         [0055]     Those of skill in the pertinent art will be familiar with the RJ-45 plug and socket cable specification and pin assignment. Two wiring standards are conventional for the RJ-45, namely, the T-568A and the T-568B designations. In terms of color, the RJ-45 uses four pairs, namely, orange, green, blue, and brown (one solid, one striped). In that regard, it will be understood that the above-noted pin assignment may be varied within the conceptual boundaries of the invention and that one or several of the pin assignments may be exchanged, replaced with a different standard, or omitted altogether.
