Primarily cost, reliability (less complex hw = less hw that can fail), and serviceability (no need to rebuy the exact same raid card model when it fails, any SATA controller will do). If you want good write performance, instead of adding N GB of cache memory to a disk controller, add N*5 or N*10 GB of system memory (DDR2 is maybe 1/5th or 1/10th cheaper per GB, and the OS already uses main memory to cache disk writes). -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
