hello everyone

today let's learn about the Seda bus

Seda bus is a serial bus

for connecting SSD or HDD an optical drive

the set of bus uses an embedded clock signal

it has a stronger error correction ability

compared with the past

the biggest difference is

that the transmission command can be checked

if errors are found

there will be automatically corrected

this greatly improves the reability of data

transmission the serial interface

also has advantages of simple structure

and support for hot swap

say the bus is composed of

pair of sending and a pair of receiving signals

data transfer through coupling capacitors

in notebook motherboards

the say the bus is usually used for them

m say the interface to connect SSD

it will be sent to a common

say the interface for connecting to a say

the hard drive

or an optical drive

also used to connect

external devices by connecting to the e

SATA interface

SATA bus is divided into SATA

1.0 version 2.0 version and 3.0 version

the broadband of version 1.0 is 1GB/s

and the speed is 150 megabytes per second

the current save a

3.0 broadband is 6GB/s

the transfer speed can reach up to

600 megabytes per second

for example

the say the bus for PCH and hard disc communication

it consists of a pair of

sending and a pair of receiving

communication through the company capacitor

in the middle

there are 4 lines in total

this is the say the bus
