SATA II - 300MBS?

[GhandiInstinct]

Anyone know anything regarding the SATA 2.0 interface? Such as specs and release dates?

why do we need it when we dont saturate the SATA I?

 

[GhandiInstinct]

Every motherboard made from 2003-now has SATA.

furthermore, when are serial ata cd roms coming out?

who cares?

I do! I'm really tired of giant ide cables...

Actually very soon

sata cd roms are out. there was an article on toms hardware about it a few months back. nothin special about it except the lack of an ide cable though

I could only find dvd burners with SATA. No cd-roms.

Interesting enough, the bandwidth of SATA2 will actually be put to good use; it allows the concept of splitting the connection(like a network switch), so you could have a board with just 2 SATA ports that drives several different storage devices. This will lead to greater saturation of the root ports that everything is based on.

Could you connect your existing SATA Hard Drive to a SATA2 interface?

you can pretty much phase out cd rom as dvd rom is as cheap as 25 dollars.. even dvd burners are reaching $50 levels..

Not true (ie. PC chips w/and/or Shuttle)... come to think of it SATA 300 is due out in the 1st 1/2 of next year but for speed performance, I would think that the HD and MoBo chipset would have to be Native...which s possible

According to serialata.org

The Serial ATA II 3Gbps phy specification was formally adopted according to the terms of the Serial ATA II agreements on July 1, 2004.

So it'll take about 6 months for solid demo units to come out (controllers and drives) and another year or so until manufacturers integrate it on their chipsets etc....

The only reason(s) I can think of are better command queueing support and interface hubs (multiple drives per channel).

There are already SATA optical drives available however they are few and far between because the interface provides no benefits to the devices.

A 52x drive can't even saturate a ATA33 channel let alone a ATA66/ATA100/ATA133/SATA150 channel.

52 x 150KB/sec = 7.8MB/sec
72 x 150KB/Sec = 10.8MB/Sec

You'd need a 220x CDROM drive to saturate a ATA33 channel 😉

Even a 16x DVDROM doesn't do it 16 x ~1.3MB/Sec = ~21.

You'd need a 25x DVDROM drive to saturate a ATA33 channel 😉
