SATA 2 Native Command Cueing and Multi Tasking. Alot better ???

I know the speed of SATA 2 is 300mbs. Not to fussed about that as we
are not even using the ATA 100 full bandwitdth yet :) 

But i am interested on what effects NCQ has on responsivness of your
computer system. Will it make it much smoother.

Example coying a file and doinf somthing. That make my system grind
toa halt. Still can use it but much easier to leave it and wait.

Iam waiting to build a new 64 bit system. An Amd X2 with SATA 2 driver
sounds IDEAL.

I never want to see an Hour glass or my system slow down like it does
now.

Thanks for any info.

It's not. It's one of the additions in SATA-II

A SATA II drive doesn't necessarily be 3Gb/s.

Actually we do with some SCSI drives which means the (S)ATA ones are on
the way. With SATA's bigger overhead the transfer limits may be similar
for ATA and SATA.

Of course not.
How on earth will delaying transfers make anything go smoother.

Whoa. Stop. Something is wrong if you are running any current operating
system and that is happening. I don't experience that even on the dog-slow
4200 RPM drive on my laptop under XP. As I'm typing this I'm copying my
whole Windows folder to a temp file and at the same time watching an HDTV
recording (not recorded on the same drive--the HD is on a server).

First thing to check is to make sure that DMA is turned on on all
drives--for XP the procedure is described at
<http://www.microsoft.com/whdc/device/storage/IDE-DMA.ms...;. Next, once
DMA is on, make sure you have enough RAM. Right click on the taskbar and
pick "task manager", then "performance" and watch the "Commit charge". If
it's more than the "Physical memory" while you're doing your normal stuff
then you need more RAM in the machine. If you've got the RAM maxed and
you're still paging heavily then put in a separate disk specfically for the
swapfile--if that is the case though then you really need a 64-bit machine
that can hold a serious amount of RAM (not all 64-bit motherboards allow
more RAM than do 32-bit, even though the processors can handle vastly more,
so make sure you get one that can).

Nope, you wouldnt be able to pick it in a proper
double blind trial without using a benchmark.

Nope. Command queing isnt even that useful with normal desktop systems.

Command queing wont help with that situation at all.

Its much better to organise your system so you dont need to copy files.
A single partition and one physical drive eliminates the need to copy files.

The best approach is a single large physical drive with just
one partition so you dont need to copy files around at all.

That's the peak burst rate of the interface and has little to do with the
speed of the drive itself.

Nope, it'll only contribute significantly to performance in saturated
server I/O.

Same with NCQ.
