How to enable RAID 0?

    I have a Linksys E3000 running Shibby's 104 tomato firmware, Big-VPN version.

    I noticed this in the changelog for release 101:
    - RAID 0/1 support. Modules and mdadm tool available in extras. Mega-VPN and AIO have RAID modules and tool build-in

    I would *LOVE* to get this working. Unfortunately I don't think Mega-VPN or AIO fit on my router's flash.
    I found "extras-mips2.tar.gz" in the K26 firmware directory.
    It has a folder called raid with the files md-mod.ko, raid0.ko & raid1.ko.
    Can someone tell me what to do with these and how I could enable raid 0 or 1?

    For now, I'd like to put a few old usb flash drives together to improve performance & storage capacity.

    A Broadcom based devices has poor HDD speed. The bottleneck is not a media itself, but USB controller. No matter how many disks you will use in RAID0, the performance will remains the same. Also, it's a soft-RAID, so it will drain CPU's (already weak!) resources.

    If you still want to set up RAID0, please refer this manual.

    PS Don't know why, but I get better performance not with:
    Code:
    $ insmod md-mod.ko
    $ insmod raid0.ko
    but with:
    Code:
    $ insmod md.ko
    $ insmod md-mod.ko
    $ insmod linear.ko
