Today?s newest external enclosure designs are based on architectures that support both SATA and SAS drives. The MegaRAID® SAS 9280DE-8e, with eight external SATA+SAS ports, is ideal for configuring these external enclosures with your choice of high-performance SAS hard drives, high-capacity SATA hard drives or energy-efficient solid state drives (SSDs). With data transfer rates of up to 6Gb/s per port, the MegaRAID SAS 9280DE-8e bring users new features and improved performance, while continuing to support all the features of the previous 3Gb/s SATA+SAS generation. Using LSI? SafeStore? encryption services, including instant secure erase and local key management, this controller provides additional security against any unauthorized access or modification of a drive?s data, resulting from theft, loss, or repurposing of drives.
