Those two products don't look awesome, because they're still bottlenecked
through the system SATA bus.  (Although they should beat the SSD).

This is better:

Because they implement their sas/sata controller on-chip, and interface the
PCIe bus.  The PCIe bus is the bottleneck, which is much faster than
SAS/SATA 6Gbit.
