FRITZ!Box 7590 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.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Enabling USB 3.0 mode

The following step is only necessary if you are using a USB 3.0 storage device:

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "USB Devices" in the "Home Network" menu.
  3. Click on the "USB Settings" tab.
  4. Enable the option "Power Mode USB 3.0" for the USB port you are using.
  5. Click "Apply" to save the settings.

    Important:If the FRITZ!Box no longer detects the USB storage device when "Power Mode USB 3.0" is enabled, then your USB storage device does not correctly identify itself as a USB 3.0 device. In this case, reenable the "Green Mode USB 2.0" option.

2 Using a USB 3.0 cable

The following step is only necessary if you used a USB cable to connect the USB 3.0 storage device to the FRITZ!Box:

  1. Use a USB 3.0 cable ("super speed") to connect the USB storage device to the FRITZ!Box. The storage device cannot be integrated as a USB 3.0 device if you use a different type of USB cable.

3 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 (Wi-Fi, LAN) being used.
  • FRITZ!Box functions currently in use and the FRITZ!OS being used.

Depending on these factors, throughput rates of up to 95 MB/s (FAT32, FTP) and 35 MB/s (NTFS, SMB) are possible. However, the write speed is normally significantly slower than the read speed.

If possible, we will optimize future FRITZ!OS versions so that the throughput is increased.
