Since you brought it up, and since I am curious.Â* I would like
to ask if there a difference between running these 2
technologies? My MB has the capability of running both (I am
using SSD Sata 6.0).Â*Â* I don't process video, play games, or do

Let's take an example.

If I run a Macrium backup, if the storage is infinitely
fast, the backup still only runs at 200-250MB/sec.
Why is that ? The software computes a checksum while
it is backing up, and that is the rate limiting step.

I have little MD5 and SHA1 programs here of my own,
and the speed ranges between 100MB/sec and 300MB/sec.
And these are far from optimal programs.

Now, given these speeds for some existing tasks,
how much difference would a 600MB/sec or a 2400MB/sec
storage device make.

The answer is... none.

Paul, Thank you for your detailed explanation. I got the point!
Maybe some details besides speed will emerge about these two
technologies. I've learned about the 4 or so types of "cell
technology", single, double, octal, etc.--though I may be abusing
their appropriate names in favor of how I think about them.
