My backups are saved on my external HDD
Its about 450GB, when I copy/move the files from my External HDD to Local Disk
The transfer rate is 28.0MB/sec -> 27.9MB/sec -> 27.8MB/sec .....->8.0MB/second?
every second the transfer rate is decreasing?
Is it Normal?

Exactly what is your backup mechanism. The transfer speed of many small files will be less than a large file where sequential transfer speeds should be higher.
Also, have a kook at how fragmented both drives are.
PS: I suggest you update your specs I doubt you have 400GB+ memory.

First i sugest you to disable your antivirus . secondly I think your external Hdd cable is slower than your local hard drive, so it may cause of limit data transfer speed
There may be the initial estimates are not correct, or that there was compression coming in to play that's not applicable on the whole drive
Run a full Disk Check to check the file System on each drive.
Compression can cause problems on data drives, and can be disastrous on OS drives.
It would be interesting to try defrag on each drive to see how speeds are affected after each. I recommend Puran Defrag Free Edition for it's excellent Boot Time defrag.
I've also seen it suggested that data drives don't need defragging but dont' see how it could hurt, and it might help. Let us know.
Theres a sticker on my External HDD cable, "USB 2.0"
thanks it help, my transfer rate is about 30MB/sec but after 2 seconds ,still decreasing
My External HDD is my laptop HDD before this Drive has bac sectors cannot be use for OS but for storage only.
What does it mean?
Something is either running on it or it thinks there is. If you don't think so then Force Dismount.
HDDs function is short bursts. It is normal for the transfer rates to decrease as the time progresses. That is just how they function. Fill up their caches and slow down. On long jobs it can get very low, depending upon how busy the drive is.
Do you know this software EXTREME COPY ?
I would use the superior Win7 functions, after assuring you have a perfect install on adequate hardware.
What are the results of each Disk Check, with both boxes ticked? Check Disk (chkdsk) - Read Event Viewer Log
