1 Here are some theories.

3 * You gotta properly align the sectors for 4K advanced format
4 * USB doesn't have NCQ which really slows things down.
5 * Copying many small files is almost always slow since they are located
6 on various parts of the drive not in a contiguous block (again see NCQ)
7 * System is set to use IDE not AHCI thus no NCQ etc
8 * You are using a secondary SATA chip such as the terrible ones from
9 JMicron or what not instead of what is on your systems northbridge or a
10 quality PCI-e HBA.
