I don't think so. It's *very* unlikely a driver can mess up linear speed - it's far more easier to mess up random IO. I don't know why it's so (it might be cause by FreeBSD's tiny MAXPHYS), but it's probably not the driver's fault. I've seen this behaviour with other controllers (including plain SATA). >> ZFS was very good, but not so much when compared to Linux file systems, > > ZFS in your benchmart is similar to UFS. Look at the read speed.
