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.

There's a difference but it doesn't seem to be night and day IME.

It makes a bit of difference to certain usage scenarios, but it's not like
your system feels twice as quick or anything like that. The most noticeable
difference is arguably a reduction in the carriage tracking noise (the
clicking and grinding) you often hear from a regular HD when performing
disk-intensive multitasking.

There are a variety of reasons for what you're seeing and the most effective
cure may not be TCQ/NCQ. If, for example, your swap file is on the same disk
as the one you're copying from/to, and the thing you're "doing" is very
memory-intensive, the constant paging to and from the swapfile will
interrupt the file copy and vice-versa. While command queueing will make a
bit of a difference in that scenario, the best solution would either be to
add memory sufficient to reduce/eliminate swapfile use, or indeed to put
your swapfile on another disk.

Without knowing the spec of your current box it's difficult to comment
authoritatively, but as things stand it sounds like NCQ alone isn't the
answer to your prayers.

Better yes! Since that was the objective. A lot better is debatable.

Lol! Just the same as you and the rest of the computer fraternity who
dismissed SCSI.

Probably not, however the functionality obviously wasn't regarded as a
necessity for a "normal" single home user since it's been around for
ages and only now is it fit for the SATA/IDE user.

Then you use a sub-optimal OS.

Fantastic! Fix software problems by buying new hardware! Kyoto is but a
a distant memory.

Stop using the most grossly over marketed OS in history and attempt to
use an OS which realistically fits your business/bollox requirements.

Any time.
