Capacity and fit

The Samsung PM1633 is a 3.84TB internal solid-state drive in a 2.5-inch form factor. It uses TLC memory and connects through a SAS 12Gb/s interface for enterprise storage arrays and servers.

SAS throughput ceiling

The SAS 12Gb/s link sets the maximum bus bandwidth for the drive. Sustained performance will not exceed this interface limit, and the 4KB random read rate reaches up to 195,000 IOPS while random write reaches up to 20,000 IOPS.

Host requirements checklist

Verify that your system provides a 2.5-inch SAS bay with a 12Gb/s controller and backplane. Confirm the operating environment stays within 0°C to 70°C and that the power supply can deliver the drive's specified current.

Questions about this item

Should I choose the 3.84TB PM1633 or a smaller capacity for my workload?

The 3.84TB model provides the highest capacity in this series; select it when you need maximum space for read-intensive workloads, otherwise a smaller drive reduces cost.

What does the 195,000 IOPS random read figure mean once the drive is installed in a server?

It indicates the peak 4KB random read performance the PM1633 can deliver under optimal queue depth; real-world throughput depends on the controller, queue depth and workload mix.

How does the SAS 12Gbps interface cap performance in practice?

The 12Gbps SAS link defines the maximum bus bandwidth; sustained speeds will be limited by the drive's internal 195,000 read IOPS and 20,000 write IOPS ratings.
