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.. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | |||||||||
