SATA Question

[Appolyons]

I was looking at harddrives yesterday online, and was curious why I wasnt seeing any SATA II drives. Obviously, SATA II is better than SATA I, but I was curious, is this link (http://www.newegg.com/Product/Product.aspx?Item=N82E16822136073) a SATA II hard drive. 'Cause honestly, I cant find one hard drive on newegg that has SATA II in the title. Am I missing something? Any help is appreciated.

Yes it is a SATAII
SATA 300/SATAII/SATA 3.0Gigb/sec is the same thing

SATA I is 150Gb/sec

Ah, thank you so much. This was really worrying me for a minute!

SATA Specifications have been evolving and have often been confusing since what one manufacturer meant by SATA2 (SATAII is deprecated (http://www.sata-io.org/namingguidelines.asp) since it is an organisation) didn't mean the same for another one. This was coalesced into what is termed SATA2.5 (http://www.theinquirer.net/default.aspx?article=25682) to attempt to introduce uniformity. SATA2 and SATA2.5 both have 300 speeds but the other aspects of SATA such as NCQ are intended to become standardised under the specification. SATA 600 is in the pipestream.

Why on earth they used 2.5 when this is bound to confuse between 2.5" and 3.5" drives heaven only knows. SATA 150, 300, 600 seem a much clearer way of describing the main series that SATA drives belong to since this is what affects most users most of the time.

AnandTech referred to the same matter 2 years ago (http://www.anandtech.com/weblog/default.aspx?bid=245) and since the web is not littered with 2.5 spec references its obvious that it never caught on.
