Is it normal to take two hours to copy a 158GB drive/partition to another one? Or is my computer not normal? It seems to take forever. It's simply too slow...

This is on an Asus M5A78L-M LX with a 560 BE. Trying to do one thing before the board is gone forever.
 
Do the math. That's ~22.5MB/s.

Old disks? Small files? Could be right.
 
do you have a paging file on each drive in your system, this could help. Also which drives?
 
It's not on a boot partition, just storage. It seems to take forever. The HDs are not that old, 2-3 years old, but not super old by any means. 500GB capacity, partitioned into 250GB each.

No paging file.
 
What are you using to copy these drives? If its file by file that will be much slower than a bit for bit block for block copy with a utility like dd or a partition cloning program. The reason is instead of keeping the heads on (or close to) the data to be read / written writing file by file will cause a multiple seeks per file.
 
This is why its a good idea to bench the drives, and create the partitions according to the speeds so the respective sizes see thier best speed.

You would be surprised what a paging file can help with. I know for me copying from a caviar blue to a caviar black 1tb sata 6 and a 640 respectively, the black is faster all around, and without the paging file on each is noticeably slower.

At the leading edge of the disk(where the paging file should be) the speed is the fastest the drive will be, at around 20% of its total the speed drops quite a bit, at around 45-55% you have lost most of its speed and the last chunk performance wise 65-84% is way slower then the rest, the last 15-20% is hella slow, so it really depends on where the information is on the disk, how much the paging file is being used etc.

Generally to have a pging file per, means the drive in use is able to page the other drive and vice versa(this is far more helpfull with slower drives) and multiple smaller partitions vs 2 largers ones helps alot as well.

For my 640, I partitioned it, 20gb/150gb/125gb/remainder, the first 2 are super fast, the next is quite a bit of drop in speed and the last is very noticable speed difference. The average speed is around 118mb/s the slowest it goes is around 48-62mb/s, the caviar blue is about the same, a touch higher on the top end, a tough lower on the low end, the burst is also important for smaller paging file usage and such in my case just under 180mb/s and 165mb/s respectively.

Anyways, I would drop a paging file on it, it can help alot, also next time you go to partition the drives, use some hard drive benching tool, and make the partitions accordingly, something like Crystal Disk mark or HD Tune.
