Pros: * 16 6 gb/s ports with a totol throughput 12,888 MB/s * 16E HBA + JBOD + ZFS = legacy hardware raid killer * Ability to expand to 1024 disks.

Cons: It is a bummer this is not available in a Low Profile model... I guess they have to stack the ports some where.

Overall Review: This is a HBA meaning there is no support for hardware raid. This is a GOOD thing! You no longer need to worry about picky controllers or disks timing out. This should be paired with several JBODS and ZFS on either BSD, Opensolariss, Linux +FUSE or Nexentastor.

Pros: The top is bright ?

Cons: I bought 4 spindle in December so far 3 have failed 1 was recovered by a format but just failed again. so 4 drive failures and 2 RMA's. one drive has 184 reallocated sectors.

Overall Review: seagate Support says that these disks we not designed to run in raid 5 which could be my problem but, they are in a very light duty NAS. Stay away from these drives.
