Why So slow?

[GoldDimTzam69]

I am transfering some data from one folder to another. Both folders are in the same hard drive and I am getting ridiculously slow speeds while transferring the data. Why is that?

Probably because there are so many small items. They may be located in various places on the disk and being copied to a further various locations.

There are small items but not a lot. Smallest item in that folder is 6.4mb. I dont think thats small enough to lower the speeds that much

There are 16 thousand items. That is quite a few. The average size of the remaining items is like 46kb.

There are about 5000 items remaining, totaling 236 MB, which is an average of 45 KB per item

The way file transfers work is in sequence - every file is considered a new transfer and so it's essentially starting and stopping transfers 16,000 times.

I always explain it like this: It's faster to transfer ONE single 300GB file than it is to transfer TEN THOUSAND files totalling 30GB because that's how data transfers work. Obviously this is just an example, and not necessarily a real-world situation, but the point stands.
