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

[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.

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?
