FRITZ!Box 3490 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 specifications.

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/ext3/ext4).

    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 of up to 30 MB/s (240 Mbit/s) are possible. However, the write speed is often significantly slower than the read speed.

If possible, we will implement optimizations in future FRITZ!OS versions that increase the throughput.
