Today’s newest external enclosure designs are based on architectures that support both SATA and SAS drives. The ServeRAID™ M5025 SAS/SATA Controller, with eight external SATA/SAS ports, is ideal for configuring these external enclosures with your choice of hard drives. With data transfer rates of up to 6 Gbps per port, the ServeRAID M5025 SAS/SATA Controller brings users new features and improved performance, while continuing to support the features of the previous 3 Gbps generation. 6 Gbps performance advantage 6 Gbps SAS is designed for backward compatibility with 3 Gbps SAS as well as with 6 Gbps and 3 Gbps SATA hard drives. Regardless of the drive speed, 6 Gbps ServeRAID controllers will deliver significant performance improvements in both read and write applications as compared to their 3 Gbps predecessors. Other new features of the 6 Gbps ServeRAID controllers include greater signal integrity using Decision Feedback Equalization, support for more sophisticated SAS topologies using Expander Self-discovery/Self-configuration, and additional safeguards to enhance data protection.
