FRITZ!Box 3390 Service

USB storage access is slow

Data transmission between a computer and a USB hard drive or USB memory stick connected to the FRITZ!Box is slower than defined in the USB 2.0 specifications.

1 Throughput lower due to functional principle

In the case of integrated systems such as the FRITZ!Box, the highest possible throughput when accessing a USB storage device is lower than that of Windows computers, for example. This is due to its architecture and is influenced by

  • software or communications protocols (SMB, FTP, USB remote connection) being used.
  • architecture of and file system on the USB storage device (NTFS, FAT/FAT32, ext2).

    Note:NTFS is a file system from Microsoft that was specially developed for use with Windows operating systems. The implementation of NTFS support by the Linux-based FRITZ!OS is technically sophisticated, which means that access via NTFS is slower than with other file systems.

  • the use of encryption techniques (FTPS, FTP over SSL/TLS).
  • transmission medium (wireless LAN/LAN) being used.
  • FRITZ!Box functions currently in use and the FRITZ!OS being used.

Depending on these factors, throughput rates between 6 MB/s (48 Mbit/s) and 20 MB/s (160 Mbit/s) are possible. Higher throughput rates can be achieved with current FRITZ!Box models.
