When can I expect a SATAII HDD from Seagate?

Hoooboy. Okay. Any SATA drive can offer NCQ...it doesn't matter whether it is SATA 1.5G or 3G, it can offer Native Command Queuing.

Why? Because NCQ is a SATA II extension, and as I said before, any SATA drive can add SATA II extensions.

Read this as if it was printed in big red, bold, flashing print...SATA II...is not a speed spec.

The speed spec is defined by SATA...not by SATA II, which is a set of capabilities (aside from interface speeds) that you can add to a SATA hard drive.

Yes, I know, I already understand that. But since you said NCQ was a possible feature of any SATA drive, I wasn't thinking it was a SATAII extension, and as such I was questioning the need for ANY SATAII extensions or capabilities as of now.

I didn't say "possible"...I said it "was". (in reference to NCQ'ing)

Don't worry, you're not the only one not getting this.

Here is what I said below:


"SATA II is just a set of extensions that can be added to either a SATA 1.5G or SATA 3G drive, providing features such as Native Command Queuing, staggered spin up, etc., etc.

A SATA drive can have some, all, or none of the SATA II extensions.
In some cases the mobo's controller must support the extensions too, such as with Native Command Queuing. All nForce4 boards support some SATA II extensions, such as NCQ. "

So if it has NCQ then it has a SATAII extension, even though it may be labeled as a "SATA150" drive.

mine gets 53mb/s according to SAndra, comapred to ~40mb/s for the ATA-133 PATA counter part. SATAII probably wont give you anything compared to SATA150 when using the same drive.

Exactly! I'm running, on this particular machine, a Maxtor DiamondMax 10 250GB SATA (150), which also happens to have NCQ.

Thanks for clearing some of that up.

There is no SATA II at all. Never will be. NCQ is not an extension of SATA I, it was included in SATA I, but was not a required component. NCQ is not a requirement for anything, as WD's "post" SATA I drives do not support NCQ either. WD has just announced one that does, but the ones they have out now do not.

Neither SATA I or whatever the 2nd generation of SATA is going to be called provide any performance benefits to a typical user. None at all. Nor will they anytime soon. Do not buy SATA drives for better performance, unless you buy a Raptor which is SATA only.

You have absolutely no idea as to what you're talking about.

i believe what pariah is talking about it that SATAII has been change to SATA IO. though SATA II drives are out in the market.
