Offering data transfer rates of up to 3 Gb/s per port in a low-profile form factor, the MegaRAID SATA 300-4XLP addresses the growing demand for RAID in high-density rack-mount chassis environments. Also, with the addition of individual drive activity and fault LED headers, you can view the status of hard drives through LEDs on the chassis. In addition to 3 Gb/s SATA transfer rates, the MegaRAID SATA 300-4XLP also supports Native Command Queuing (NCQ) and Enclosure Management (SAF-TE)
