    Using Linksys WRTSL54GS with Tomato v1.28.8752 ND USB vpn3.6. Connected an external USB drive FAT32/NTFS to the USB port of the router.

    The harddisk is mainly used as a media storage to stream the audio/video media as a shared network location available to other DLNA media players on the network.

    I have noticed that the transfer speed when writing to a NTFS formatted network share on the router is pretty slow around 1 - 1.5 Mb/s. Is that the case with everyone using a similar setup ? It is very slow somehow bearable since I use the connected drive as a media dump location to store all the media related files.

    Similarly now I can see that the read rate from the shared network folder (on tomato usb connected drive) is also somewhat slow, I can assume that safely when I play hi-definition MKV files on my NMT and they start stuttering specially at the scenes with high bitrate 5 ~ 7 Mbps . Usually encoded at 4.1 or 5.1 Level with AC3/DTS sound.

    I have checked the MKV files are correct by copying and connecting them directly to the NMT on a USB flash drive, they play perfectly in such cases. I have a 100MBps wired connection between the router and the NMT, there is no network cable attenuation / line loss. So it leaves the factor of the combination of SAMBA/Linksys/Tomato not been able to stream from the connected USB at the desired reading date.

    I have tried that with stock SAMBA installation (supplied with tomato) and also recently when I upgraded to SAMBA 3.5 from the optware repository. The behavior is almost the same, (the newer SAMBA version however is supposed to improve the read/write rate).

    So has anyone used or checked the read/write rate or has used the router in a similar media streaming setup and has some workable good advice for me.

    Thanks for the info.

    I don´t have personal experience. But If I´m right, you have to use native linux file system like EXT3 to get faster transfer speed. But don´t have high expectations.

    Well that sounds like a distant possibility to me :). Since the harddisk is sometimes also attached to the Windows PC to copy files to and fro. And Ext3 write support in Windows is still very unreliable, and has corrupted my data once earlier.

    Anyways will try having some other alternative to fix it.

    You can try it with another usb device. If transfer speed and stability will be high enough with EXT3, you can consider make USB disc only for router to make cheap NAS. I expect speed between 3-5 MB/s (40mb/s).
