    Can anyone report their max/average speed for usb nas? Using latest Toastman Ext build (1.28.0497) and it max. at 1700 kbytes.
    I had similar behavior when using stock firmware but only in samba transfers. Ftp transfers in stock firmware was much better but in Tomato speeds in both samba and ftp are equally poor.
    I'd like some feedback from your experience to see whether this is the norm for Tomato.

    With stock firmware 8260KBps (8MB/s), when I had tried toastman I saw the same speeds are you posted, around 1,700KBps... sadly that was WAY too slow for me.

    Please search the site, there are hundreds of post on here explaining the phenomenon of slow speeds on Tomato versions, and how to improve the situation.

    Hi Toastman. I did a search before posting. Most of the search results where mostly relevant to wifi speed issues (drops) and the ones related to usb speed transfers reported decent speeds. The only similar post I found is this one but without resolution to the problem. The keywords I used are a combination of "usb" ,"speed" , "nas". Not sure what else to search for.

    Thanks for mentioning this post Toastman. Sadly I have to wait as I have no space to put my hdd data and make the switch from NTFS to EXT3.

    In the thread it states that the code fix was added by Victek in Beta RAF. Any plans to include it to your releases as well?

    It was added at that time. However, while it seems from the article that this is a kind of magic cure for all ills, it only fixed issues which were due to the HDD being incorrectly set to use USB 1.0. Other issues still exist for some people.

    Using a 1GB SanDisk U3 Titanium USB stick formated as ext2 I get the following ftp throughput via Gigabit Ethernet access on a Linksys E4200v1.

    Firmware: v1.28.0497 MIPSR2-Toastman-VLAN-RT-N K26 USB VPN

    FTP Read(get): 11052.16Kbytes/sec (~11MB/sec)
    FTP Write(put): 7930.36Kbtyes/sec (~7.9MB/sec)

    Using HDTune (Disk benchmark utility) on Win7 we get the following raw access stats for the USB 2.0 stick as not all USB sticks are born the same.

    Transfer rate
    Minimum: 13.6MB/sec
    Maximum: 14.2MB/sec
    Average: 14.0MB/sec
    Access Time: 1.2ms
    Burst Rate: 10.7MB/sec

    That's good enough for me.
