Details

Storage-Speed is the term used here for the filesystem perfomance of internal and external storage media. This covers:

• USB-Storage
• Internal-Storage (if provided)

This article collects raw sequential filesystem speed tests for some models.

The tests are performed using dd to read and write a huge test file, and time to measure the time this takes.
This method measures the performance of the USB-Controller, its link speed, its drivers and the filesystem drivers.

Current storage performance ranking:

• 7530ac - 205 MB/s read, 82 MB/s write - SSD @ USB3 - 4-core Dakota @ 717 MHz (ARM)
• 7581 - 93 MB/s read, 104 MB/s write - SSD @ USB3 - 2-core BCM63 @ 1000 MHz (ARM)
• 7590ac - 81 MB/s read, 52 MB/s write - SSD @ USB3 - 2-core 4-threads Seale @ 1000 MHz (MIPS)
• 7490 - 69 MB/s read, 28 MB/s write - SSD @ USB3 - 1-core 2-threads VR9 @ 500 MHz (MIPS)
• 6490 - 31 MB/s read, 28 MB/s write - SSD @ USB2 - 2-core Puma6 @ 1200 MHz (ATOM)
• 7320 - 28 MB/s read, 16 MB/s write - SSD @ USB2 - 1-core AR9 @ 393 MHz (MIPS)
• 7390 - 19 MB/s read, 12 MB/s write - SSD @ USB2 - 1-core Fusiv @ 500 MHz (MIPS)
• 7240 - 17 MB/s read, 8 MB/s write - SSD @ USB2 - 1-core UR8 @ 360 MHz (MIPS)

This list shows that the USB-Version is the major bottleneck, followed by CPU core type and horsepower.
Depending on the way storage is accessed and used further bottlenecks apply:

• Online-Storage requires USB-Storage for buffering and uses the HTTPS based WebDAV protocol
• FTP access is handled by ftpd and uses the FTP or FTPS protocols
• Samba access is handled by smbd or nqcs and uses the SMB protocol, which may be encrypted
• DLNA access is handled by mediasrv and uses the UPnP-AV protocol
• fritz.nas and MyFRITZ! are handled by ctlmgr and luacgi and use the HTTP or HTTPS protocols

All these IP based protocols slow down due to packet fragmentation, TCP based protocols additionally due to the handshake.
Encrypted protocols, unless hardware accelerated, additionally eat CPU. More cores can handle this better than fewer cores.
