I have a couple ~1GB folders that I am copying from my 128GB Samsung 830 SSD to my 250GB Samsung 840 SSD (Brand new). It goes at around 250MB/s as expected for the first half, but then it stalls partway through. It will sit at the halfway point chugging along at 7MB/s.
I have tested other folders of similar sizes and they copy at the expected speeds. It seems like about 50% of my folders do this. Why is this happening? I have both SSD's optimized.
Clarification: The drives benched at 250MB/s READ. They both got around ~600MB/s write. I am using SATA3 6GB/s with AHCI enabled. It looks like when I copy the folders within a single drive, it goes blazing fast as expected. It is only when copying from one to the other that it goes really slow.
