A kind of CD-ROM drive with the SATA interface
[technical field]
The utility model relates to a kind of CD-ROM drive of SATA interface, particularly a kind of CD-ROM drive with the New type of S ata interface.
[background technology]
Universal day by day along with science and technology, and SATA (the serial advanced technology is additional, SerialAdvanced Technology Attachment) technical manual is universal day by day.The underspeed that traditional USB interface provides is to support following Large Volume Data transmission requirements.And existing SATA interface but can't provide power supply simultaneously also only so that speed to be provided simultaneously.
In being the patent of CN1534499A, the Chinese patent publication number disclosed a kind of storage element that forms in conjunction with the additional technology of a serial advanced technology with flash memory array.This storage element comprise can accept read write command and for can wipe, non-volatile memory module (abbreviating the flash module as).This advanced technology is additional/and the flash controller is configured in order to provide the serial advanced technology additional functional and compatible with common flash memory operation, reads and eliminate aforesaid assembly as program design.
More common CD-ROM drive is divided into built-in, external 2 kinds at present:
General external interface all adopts the USB2.0 interface, and the speed 480Mb/s that this interface provides is not enough to support following Large Volume Data transmission requirements.And computing machine often just can load USB2.0 and drive after the WINDOWS booting operating system gets up, so difficult realization during external CD-ROM drive pilot operationp system.And the electric energy of USB interface output comes from mainboard, and maximum is no more than 1000mA, so traditional external CD-ROM drive needs independent supplier of electricity to use, for very inconvenience of mobile office user.
And built-in ide interface belongs to internal interface, and the interface rate theoretical value is 133MB/s, has not reached the upper limit, does not have room for promotion.All volume is very big for plug, socket that particularly this interface uses, can't accomplish external, hot plug.
For existing CD-ROM drive, if use existing SATA interface that speed can be provided, volume is little, but can't provide power supply simultaneously, must increase a power interface in addition for the normal use of existing SATA interface, be equipped with corresponding other power paths such as power lead.When using such CD-ROM drive, can produce the inconvenient problem of carrying.In addition, because power lead is the accessory of this CD-ROM drive necessity, in case leave behind power lead then make this CD-ROM drive to use, for the user brings trouble in the use.
