This section partially describes the interface requirements as implemented on Seagate 1200 SSD drives. Additional 
information is provided in the SAS Interface Manual (part number 100293071).

This section lists the SAS-specific features supported by Seagate 1200 SSD drives.

Seagate 1200 SSD SAS drives have two independent ports. These ports may be connected in the same or different SCSI 
domains. Each drive port has a unique SAS address.

The two ports have the capability of independent port clocking (e.g. both ports can run at 12Gb/s or the first port can run at 
12Gb/s while the second port runs at 6Gb/s.) The supported link rates are 1.5, 3.0, 6.0 or 12.0 Gb/s.

Subject to buffer availability, the Seagate 1200 SSD drives support:
• Concurrent port transfers—The drive supports receiving COMMAND, TASK management transfers on both ports at the 

same time.

• Full duplex—The drive supports sending XFER_RDY, DATA and RESPONSE transfers while receiving frames on both 

ports.
