Mine is fine. Why don't you try an another hard drive?

With ext2 you should be able to reach 5MB/s read and 6,5MB/s write speed if connected via lan cable. This is the maximum this routers cpu can handle. USB needs a lot of cpu power in addition to that the network logic is done in software which also consumes cpu power.

Enabling Qos, Access restrictions and some other features increase the cpu load and therefore decrease smb performance.

Hi, these are my results with DD-WRT 14929 big e2k-e3k (no Kong mod) on E3000:

- FTP upload -- about 7.9 MB/s;
- dd if=/dev/zero of=/mnt/manyGBfile -- about 13 MB/s.

On Kong 18050M with miniDLNA nv60k I have about 4 MB/s for FTP upload, but I am able to upload two different files at once at this speed (4 MB/s each), using FileZilla. Just measured the speeds now for this build: about 5500 kbytes/s download speed; about 4600 kbytes/s upload speed (using only one thread with Total Commander Ultima Prime).

I use a Samsung G3 2 TB hard disk with its own power source. The Mnt partition is ext3 formatted. The computer is connected to the router via Cat5e cable. LAN connection LED is green, showing a 1000 Mbps connection.

Due to the limited RAM memory of the router, the speed isn't comparable with the speed of a NAS (difference in caching). But for what I need it is enough.
