As you can imagine, the RocketRAID 2680 from HighPoint is all about cost effectiveness and value. The RocketRAID 2680 is a PCI Express x4 card with a built in XOR processor and directly supports up to eight SAS or SATA hard drives, however through an expander, it can support up to 128 hard drives. The card can be managed either through its own BIOS at startup or through a web interface with Quick or Background initialization modes for instant RAID setup.
While it can neither wash your car nor clean your stove, its higher end counterpart, the RocketRAID 4320 is another story.
The RocketRAID 4320 has its own processor running at 1.2 GHz, IO processor for parity calculations and 256MB of ECC SDRAM. The card runs PCI- Express x8 for all your bandwidth needs and like the RocketRAID 2680 supports either eight SAS or SATA drives through the two mini SAS ports or through an expander up to 128 drives.
