It
is important to know ATA device first. ATA
stands for Advanced Technology Attachment.
It is a standard for connecting CD-ROM drive or hard disc device to IDE
interface. ATA is divided in two parts:
P-ATA (E-IDE), CD-ROM standard and S-ATA device, the latest version.
Those
are the brief information about the ATA standard.
Here
is information about P-ATA and S-ATA.
First,
The
letter P in P-ATA stands for parallel.
Data
moves through several cables in parallel.
ATA-100 and ATA-133 hard disc are all P-ATA method.
ATA-100
has 100MB/S standard (the maximum transfer rate per second), and ATA-133 has
133MB/S standard.
It
uses a wide 40pin cable which is used in general hard and CD-ROM. By using a parallel method, two devices are
connected in one cable (Master/Slave).
IDE
/ E-IDE / ATA-100 / ATA-133 are connected with 40pin cable.
Second,
The
letter S in S-ATA stands for serial.
It
is the latest version of ATA standard and used in hard disc.
It
is an in-line data transfer method with narrow cable (2cm wide). It has faster transfer rate than existing
P-ATA.
The
standards of S-ATA I and S-ATA II are S-ATA method, and one device can be
connected to only one cable and one port.
S-ATA I has 10MB/S standard (the maximum transfer
rate per second), and S-ATA II has ??GB/S standard.
