Pay attention to the SATA connector

About what the SATA connector looks like, everyone knowsowner of a modern personal computer. The Serial ATA serial bus (hence the name), intended for connecting optical drives and hard drives, has replaced the obsolete parallel (PATA).sata connectorMany still remember IDE hard drives,which for connection to the motherboard used wide and flat trails, consisting of 40 and 80 conductors. It can not be said that they violated the air circulation or were uncomfortable, because installation and laying were not performed every day. The reason is that the "ceiling" of the transmission speed was reached, amounting to 150 megabits per second, and the addition of additional cores to protect against mutual interference was inexpedient. As a result, another standard was proposed - SATA, which by some parameters exceeded PATA (IDE). All modern hard drives are hdd-SATA devices.

Rules for handling ... connectors

The serial bus bus is practicallycan not be confused with anything else. This is a cable with dimensions 10x3x30 (width, thickness, length). As a rule, its shell is red (although there are models in blue, yellow and orange scales). Both sides of it have a SATA connector. Although the developers took into account some disadvantages of PATA, ignoring the rules for handling SATA loops, we can not expect stable and continuous operation of the disk subsystem.hdd sataFirst of all, you need to connectcarefully inspect the SATA connector on the wire: its special design does not allow an erroneous connection. The connectors on the board and the cable (sometimes referred to as the plug) must match the internal protrusions. Conclusion: excessive effort is unacceptable. Few people know that the SATA connector does not involve frequent on / off cycles. The internally mounted contacts are thin, curved (spring-loaded) copper strips, which, when connected, gives a qualitative electrical contact. With frequent switching, the clamping force is reduced, which can lead to data transmission failures.sata usbConclusion: you need to use a special solution - eSATA or, if there is no other way out (as in the case of laptops), SATA-usb converters, which allow connecting devices not to the serial ATA bus, but USB.

Unclear drawback

Some users have already encountered this issuethe fact that sometimes a SATA device completely ceases to function for no apparent reason or there are various transmission failures (from errors to slowdowns). One of the reasons is that the connectors of the loop and the board are disconnected. It is possible to restore the operability by removing and re-enabling the loop. However, there is a more reliable solution. It is necessary to purchase such a SATA cable, in which a metal latch-lock is located on the connector. Thanks to her spontaneous disconnection is almost impossible. This train is 30-50% more expensive than usual. Some manufacturers of motherboards complete with the product offer one such cable. In general, SATA connectors are quite reliable and very rarely fail. If you follow the recommendations above, then the duration of their operation is the same as the entire board.
