It seems that your target drive's capacity is quite large. You can try 32KB/64KB if the memory overhead is not too big. Increase the block size until the memory overhead is acceptable.

Hi and thank you for the reply!
Where I can see the memory overhead?
And what is the acceptable amount?

regards,

For the block size: I just tested my systems performance with Crystal Disk mark on any block size, and I found that on my system 32k blocks gave the highest performance.

The overhead seems high. I think you may change the block size to 128KB or bigger to reduce the memory overhead.

I think this is acceptable. If you want to reduce the overhead even more, you can change the block size to 256KB. But generally the performance of 128KB should be better than 256KB.
