Weak performance of USB drive on RT-N66u

[PrivateJoker]

Transferred file between the router and computer (on 5G): Windows 8 ISO (2.8Gbyte).
Connection speed 702 Mbps
Signal strength: -60db
Used program: Total Commander
Op system Win 8 (64bit)

I used to check the wireless speed with NAS Tester http://www.808.dk/?code-csharp-nas-performance which produced similar result with the 400Mbyte test file size

Thank you for sharing that further info. Wow that AC connection speed is funny to look at (my eyes aren't used to fast and furious AC #s)! Nice. . .anyway, I think that is pretty good performance out of a NAS that is not packing big CPU power.

Thanks! I forgot to note that both the original ASUS and Merlin firmware produce similar transfer speeds. Btw, by default the WD NAS has non optimized smb configuration. I spent days with testing the different options and their effect to the transfer speed (default r/w speed was around 14Mbyte/sec).

FWIW, I just tested the fastest drive I had laying around, but in a USB 2.0 adapter, just for the heck of it.

Samsung 840 SSD 500GB MZ-7TD500 in a StarTech SATADOCK22UE USB 2.0 dock, formatted EXT3. Tested w/ LAN Speed Lite on Win8 Pro64, 300MB file.

- Connected as a shared volume through NAS's USB port over SMB by gigabit wired connection (eg no RAID, no nothing, just giving a USB dock a way to connect to network). Writes 293.97 Mb/s (36.75 MB/s) & Reads 602.65 Mb/s (75.33 MB/s). That read # is higher than I believe USB 2.0 should allow (and actually that write # is pretty high too), but I think the read at least is somehow getting some favorable mojo from the NAS's CPU.

- Shared through RT-N66U SMB share in exact same dock, etc. Writes 72.41 Mb/s (9.05 MB/s) & Reads 102.04 Mb/s (12.75 MB/s). Based on my speeds testing a USB flash drive, it probably makes sense to at least connect a spinning drive to get best possible txfr speeds, cause it can txfr more than my (new high speed USB 3.0) flash drive could bring to the interface.

- Connected directly to PC's USB 2.0 port, reformatted in NTFS (can't r/w EXT3 natively). Writes 245.23 Mb/s (30.65 MB/s) & Reads 278.61 Mb/s (34.83 MB/s).
