The USB4 Version 2.0 specification's characteristics include maximum data transfer speeds up to 80Gbps in either direction 40Gbps per lane, and total of four lanes or an optional 120Gbps across three lanes; USB 3.2 data tunnelling to achieve speeds greater than 20Gbps; alignment with the latest DisplayPort and PCIe ...
There are various FAT formats as well, including FAT/FAT16 (max volume size 4GB, max file size 2GB), and FAT32 (max volume size 2TB, max file size 4GB).
USB 2.0 transfers data at a top speed of 480 megabits per second (Mbps), while USB 3.0 can transfer data at up to 5 gigabits per second (Gbps). You can identify USB 3.0 connectors by their blue colour and initials SS, which stand for 'SuperSpeed'.
Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. Reliable exchange of data is ensured at the hardware level using error detection. Data are transferred in the same manner as in Interrupt Transfers, but have no defined polling rate.
Maximum packet size of a bulk endpoint depends on the bus speed of the device. For full speed, high speed, and SuperSpeed; the maximum packet sizes are 64, 512, and 1024 bytes respectively.

Most USB 2 users report that they can only reach about 30MB/sec between the computer and a USB device, even though the USB 2 specification claims to support 480Mb/sec (or 60MB/sec) transfers. However, in practice the maximum transfer limit will usually be constrained by the USB 2 device itself.
