Need sata I or Sata II info

The computations above are not correct:

SERIAL ATA ("SATA") uses a SERIAL protocol,
which includes one start bit and one stop bit
for every 8 data bits i.e. 10 bits per byte.

Thus, 1.5Gb / 10 bits per byte = 150MB/second

3.0Gb / 10 bits per byte = 300MB/second


> Today's hard drives cannot even come close to using all of the bandwith of SATA 1, hell the fastest drives you can buy can barely use 10% of the theoretical bandwidth of SATA 1, let alone SATA 2.


This latter statement is also not correct:

Western Digital's newest WD10EACS is rated
at 1,156 Mb/second (buffer-to-disk),
which is 77.0% of the bandwidth of the SATA-I
150MB/second interface (not 10%):

> SATA 2 is purely marketing hype to sell more drives.

It's NOT "purely marketing hype" [sic].
For that to be true, there would be absolutely
no differences between the two standards,
and that idea is easily disproven.

SATA-2.5 supports a number of features that are
just not available at all in SATA-I HDDs e.g.
Native Command Queuing, Staggered Spin-Up,
and Hot Swap, to name just a few.

There is plenty of documentation already on the
Internet about SATA-II and SATA-2.5.


Humans need to read before they write;
hard drives need to write before they read.
