Re: [t13] What's the difference of eSATA Hard drive and normal SATA-II hard drive?

2006-07-09 Thread Alvin . Cox

From the SATA 2.5 specification:

A Serial ATA device enclosure
with a corresponding external connector. A buffer IC is
required to interface to a Gen1i/Gen2i
Serial ATA device unless the Serial ATA device is
Gen1m/Gen2m compliant and designed for
direct external connection.

In other words, normal SATA hard drives
are electrically i specification rather than m
specification and are not necessarily designed to handler the higher ESD
requirements for external connections.

Hard drive and normal SATA-II hard drive?








Hi, Members:

As to title, eSATA ia introduced in
SATA-II specification, I saw there is eSATA HD in market, what's difference
to normal SATA-II HDD, 
Maybe it has integrated the voltage
swing translator?

Sincerely,

In reviewing the ATA/ATAPI-7 V3, R4, Figure 18, I see that the vertical
location of the SATA connector is listed as 3.5 mm from the bottom of the
drive.  However, I am unsure where on the connector the top measurement is
made.  Is it the top of the connector, the top of the L on which the pins
are mounted, the location of the pins, or ???  What part of the connector
is
3.5 mm from the bottom of the drive?

Any help in clarifying this would be appreciated.

Thank you,
