In hard-disk player-vehicle and vehicle drive video recorder, the disc are two types available, namely, SATA and PATA. The next briefly explain the difference between the two.
PATA stands for Parallel ATA. Parallel ATA drives have a long history and now we ATA33/66 ATA100/133 ATA150.
SATA stands for Serial ATA. The writing speed is ATA100 65MB / s, but the speed of the first generation of SATA 150MB / s, andthe second generation reaches 300 MB / s. SATA will replace PATA as DDR and SDRAM.
The Port of hard drive left of the hard drive and the host, transmission of data between disk cache and the memory of the host country, thus the quality of the port has a direct impact on the speed and functionality of the system. In general, we have two types of IDE and SATA port. The first one is usually applied in time to the player and recorder in the morning.SATA has just been created, it is very popular, with a promising future for the product line vehicle.
IDE:
IDE stands for Integrated Drive Electronics ", the integration of the washer hard disk controller and the body des This reduces the number and length of cable from the hard, reinforced the credibility of the data so that the production of disk light, the producers need not worry if yourThe hard drive is compatible with the controller manufactured by other companies. It also makes the hard drive installation more convenient for the customer. IDE CD-ROM is very important, because the IDE port is kept updated with the function of it getting better, you also have a high quality report. IDE stands for a kind of hard disk, but in actual application, people used to called ATA-1, the generation of trees IDE, but was killed, as the development of technology brings. Many other types of port was then, as ATA, Ultra DMA, Ultra DMA, and all belong to the IDE hard disk.
SATA:
The hard disk SATA port is also used as a SATA hard disk, the disk trend in car electronics products. In 2001 he formed the Commission Serial ATA, Intel, APT, Dell, IBM, Seagate, Maxtor, set the standard for Serial ATA 1.0. In 2002, even though the SATA> Hard Drive products not listed, the Serial ATA 2.0 Commission has set the standard for Serial ATA. Serial ATA Serial accepts the connection mode data bus and Serial-ATA takes the clock signal, which have a greater capacity for error correction embedded.
Compared to its predecessor, is its most important difference is that examining the transfer order, in addition to the data. It is correct when an error is detected, which improved to a large extent, the credibilitydata transmission. In addition, the structure is simple and SATA supports hot-swappable as well.
SATA connector is a completely different type of disks. Compared PATA, SATA has several advantages. On the one hand, the SATA data transfer mode in a consecutive series, a piece of data at a time, thus reducing the number of pins on the SATA connection and the number of cable connections as a result, its effectiveness can be improved. Indeed, Serial ATA4-pin only, and are created in the connection of cables, cable grounding, data transmission and receiving data. In addition, this structure minimizes the consumption of the system and makes it less complicated. On the other hand, Serial ATA is a starting point higher, with lots of potential.
The data transfer rate of Serial ATA 1.0 can be up to 150MB / s, which could even be higher than the last edition of PATA, ATA/133, data is transmitted at a speed of only 133MB / s is alsoSerial ATA 2.0, up to 300MB / s SATA data and, finally, at a speed of 600MB / s transfer
Technically, how much faster is SATA and PATA?
Since SATA will replace PATA, SATA, what are the advantages over PATA? Comes first is the speed, as we have, the second generation of SATA can transfer data at 300 MB / s mentioned, and the third can be as high as 600 MB / s. Therefore, in order to achieve the speed, SATA, PATA so advanced. What's more, the mode of transmissionSATA is much better than IDE. SATA resume transmission to a single IDE channel during transmission takes multi-channel code. Literally, some think that the multi-channel needs to be faster than one channel, but not the truth.
The reason for this is that SATA is not a speed limit on its frequency as an IDE. The transmission line is the SATA transfer rate is 30 times faster than IDE. IDE to transmit 16 signals at a time, and if the signals do not arriveNow there is a delay or will be errors in the data. As a result, the transmission speed of the bit stream is slow to correct mistakes. SATA-bit data transfers is one at a time, and speed of the bit stream much faster. In addition, the improvement of SATA is another that his data in a row, with better heat dissipation, and smaller and easier connection of the disk. Compared with IDE, SATA is much lower consumption, the absolute benefit iscar, along with its unique technology CRC so that data transfer secure.
After this level of technology, products Yusong select your hard disk port like this: IDE ports for the vehicle MP4, MP5 vehicle adopt dual-port, that is, both IDE and SATA drives can be used. All hard disk recorder adopt SATA port.
