Windows 7: Sata 6Gbit/psec - does it double your speed?

Sata 6Gbit/psec - does it double your speed?

Quote:
"Those of us in the business of keeping an eye on new technologies wonder why the buzz about SATA 6Gbit/sec. (a.k.a. Serial ATA Revision 3) hasn't been louder than it is."

"I would wait at least four to six months before plunging into SATA Revision 3 technology. That will allow prices to drop a bit and the technology itself to mature. While Seagate has packed the Barracuda XT with 64MB of cache, I believe that 128MB would be better, given the optimal speed of the interface, and I can honestly speculate that Seagate will get here.
I suspect that Western Digital will be tweaking the firmware on its Caviar Black as well. What you can't do is achieve the overall performance advantage -- which in some cases is admittedly slim -- offered by the 6Gbit/sec. drives themselves."

Eh?
You lost me!

It clearly says "SATA 3" on the above blurb
"A.k.a Serial ATA Rev. 3"

If you mean USB 3.0 Test - i'll humour you with this link too

I have a new WD SATA 3 (6GB's) HDD .. But can only test it with an older SATA 2 Mobo.

It seems like there's some performance improvement .. (backwards compatible) ..
But nothing to shout about.

I'm waiting on some tests with a newer USB 3.0 and SATA 3 Capable Mobo...
Or maybe a card ... There might be one of These in my future

It doubles the theoretical throughput on the interface.

However, since current drives are incapable of maxing out the interface of SATA 3.0Gbps by a fair amount....it's absurd to think that a faster interface will make any improvement.

SATA 3 is a worthless investment if you are using a mechanical HDD. They barely make full use of SATA 1 speeds. Must have a solid state drive to get even close to the full potential of SATA 3. (And I know the committee that governs SATA does not want this to be called SATA 3, but SATA 6Gb/s [product name] is just so freaking stupid. It is the third revision for ffs.)

Actually, SSD's are not even yet maxing out SATA 3.0Gbps interfaces. Technically that interface can handle 385MB/s...but with overhead it's closer to 300MB/s. I've yet to see an SSD drive max out that interface.

Well didn't mean SSD were maxing out, just saying they are what can get close to the potential :P

I'm sorry, I misread your post. I thought you said SSD's were the only thing coming close to max out 6.0Gbps. But you said Sata 3.0Gbps. And you are absolutely correct with that.

This is the reason for the arguing between Sata 3 and Sata 6.0Gbps naming....because of the speeds and such, it's easy to miscommunicate.
