    Hi,

    I've been browsing through the mailing list archive, but could not find the
    answer/conclusion/solution to this...

    Running FreeBSD 5.4... three machines with twe/3ware 8000 and three twa/
    3ware 9500-8 controllers. All of them running RAID 1+0 without write cache
    since we dont have battery backup unit. All of them Seagate 7200 SATA.

    I get about 46Mb/s write on the 8000 series and only 5(!)MB/s on the 9500 series.

    How is this possible? Machines are in production so I can do very little
    testing... Any ideas?

    Alexis
