Definition

What is IDE?
 IDE
or EIDE: Enhanced Integrated/Intelligent
Drive Electronics
 An ATA specification (the terms are often used
interchangeably)
 Most common disk interface for hard drives,
CD-ROM drives
 hard drives that use parallel signaling.
What is SATA?

Serial Advanced Technology Attachment)

Is an evolutionary replacement for the
Parallel ATA physical storage interface

based on serial signaling technology
Structure of IDE



- 40 pins arranged
parallel, 80-wire cable
- Jumper:10 pins for
master/slave/cable
select
- Length of the IDE
cable 45,72 cm
Structure of SATA



speed data transfer to
150 MB / s
SATA data cable has
two flat 7 plug pins
Length of the SATA
cables can be up to 1
meter

Interface

IDE and SATA drives are not interchangeable
without an adapter.
IDE
SATA
uses a 40-pin ribbon cable that
can connect up to two drives
SATA uses a much
smaller 7-pin cable that
will only allow for one
drive connection
runs in parallel (data are sent in
groups as compared to serial
connections with a single
stream of data. The receiving
end will have to wait for all
streams of data to arrive before
it can be processed)
runs in serial (data
streamed with just one
connection and eliminate
the delay)
Power Connection
IDE
uses a standard 4pin Molex power
connection found
on virtually all
computer power
supplies
SATA
uses a new power connection that
has a 15-pin connector (Instead of
the standard 5v or 12v in the Molex
connector, SATA power connectors
also have a 3.3v line. The SATAs'
new power connector also allows for
hot-plugging or plugging in the power
while the computer is on. This is
accomplished by having a ground
contact that is longer so it connects
first.
Data Transfer Rates
IDE
SATA
ranges in data transfer rates ranges in data transfer rates
from 100 MB/s to 133 MB/s of 150 MB/s for SATA I and
300 MB/s for SATA II
Command Queuing
IDE
SATA
operates on a FIFO method
for handling commands
perform commands in the
order that they are received.
has multiple commands
within the drive
simultaneously.
store commands up to
perform them in a much
more logical path based on
speed and performance
instead of which command
was first
Hot Swapping
IDE
SATA
can only be used as a
hot swappable drive if
they are used inside of a
hot swappable adapter.
IDE drives do not have
this functionality built in
uses a new type of
power connector, they
are able to be plugged in
while the computer or
power supply is on
The Aim of SATA standard

Make a HDD :
 using
low voltage
 Use much lower signal voltage levels
 Less wire
 Taking less place in PC
 Increase the spread speed
The aim of IDE standard
-
-
-
Make a controller that suitable to ST506
standard
Catching Track ability
Separate the controller out of the
interface standard
Compatibility of IDE





IDE interface compatible with the IBM controller
Primarily desktop interface is IDE exposed 10
years ago
PCI EIDE controller card
Windows 2000/XP/2003/Vista
CRC error checking function
 only
be performed on the data being transmitted back
Compatibility SATA

PCI SATA controller card

Windows 2000/XP/2003/Vista

Integrated SATA CRC on both levels of
command and data packets
SATA and IDE application

Great for transferring data between IDE devices
and Serial ATA HD

Ideal for business and enterprises using a
combination of IDE and Serial ATA HD

Make the best HDD for PC

Make USB SATA/ IDE ( pocket HDD)
Conclusion

Definition and structure of IDE and SATA

Comparison between IDE and SATA

The aim of 2 standard- Compatibility
application
