SAS drives are far from always being the best choice, because absolute IOPS or throughput numbers do not matter. What only matters in the end is (TB, throughput, or IOPS) per (dollar, Watt, or Rack Unit). 7500rpm (SATA) drives clearly provide the best TB/$, throughput/$, and IOPS/$. You can't argue against that. To paraphrase what was said earlier in this thread, to get the best IOPS out of $1000, spend your money on 10 7500rpm (SATA) drives instead of 3 or 4 15000rpm (SAS) drives. Similarly, for the best IOPS/RU, 15000rpm drives have the advantage. Etc. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
