We have about 7 serverraid card from 4L to 5i. All of them is sitting on

significant faster, as we measured with bonnie++. Even the old aic7892 is
faster (these built-in scsi controllers on xseries motherboards).

The 6i and 7 series of cards seem to have quite a bit better relative speeds. Certainly the 4Lx cards can be outperformed in simple "hdparm" tests by a 3ware SATA controller/disks of half the price..

Plus, software RAID can't provide good performance on many server/DB applications without risking data loss in certain cases - for such things one really wants something with a battery-backed cache on it..
