Yes. Like What Garrett said, this comparison is between *enterprise* SATA and SAS drives. But I mean *consumer* SATA drives. So my statement should be changed to " the price delta between sas and laptop sata drive under the same capacity is not small like USD30 at all. ☹" > SAS would be cheap at twice the price.

Even replaced with SAS drives, the effort is still in vain. Anyway, it looks like there is a very clear gap between commodity and enterprise market. I definitely understand it is because of different business model. LSI and ADAPTEC are enterprise-oriented. And so far I cannot find commodity-oriented(Marvell?) HBAs working in illumos. The on-board AHCI SATA interfaces are friends for individual/home users. _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
