Why does mass storage send a 16k data packet into multiple data packets? #406
Comments
Depends on the flash drive. Oftentimes, some support larger ones, some do not. But anyways, the ScsiWrite and Read commands currently only support some smaller chunk sizes. Currently, there is a read command 32, which probably speeds up transfer by a lot if usb drive supports it. See here: https://www.seagate.com/files/staticfiles/support/docs/manual/Interface%20manuals/100293068j.pdf I am happy to take a PR. But as the USB spec is complex, it is hard to support each of these flawlessly. |

I have a 16k data packet. Why is it divided into 5 reads? Can I read 16k data packets at once? Instead of subcontracting to read
