Bulk transfer of a bunch of small files almost always runs significantly slower than transferring the same amount of data as one big file due to the overhead associated with creating files. | |

| Nov 12, 2021 at 15:07 | comment | added | Paamand | This is a reasonable suggestion. I will do some testing. This transfer was many small files with identical size. The USB sticks are brand new USB3.2, so writing speed was also waaay slower than expected. | |
| Nov 11, 2021 at 22:20 | comment | added | Austin Hemmelgarn | This was my first thought also. About 90% of the times that I’ve seen oscilating transfer throughput with a stable frequency like this, it’s been a case of harmonic interaction between the sampling rate and the transfer frequency. | |
