What interface and bandwidth does this SSD support?

The drive features a native SAS 3.0 controller with 12 Gbps bandwidth connectivity. This optimized interface supports dual-port high-availability configurations and ensures compatibility with standard enterprise server infrastructure. The SAS 12Gbps interface enables reliable multi-path I/O operations for mission-critical applications.

What is the random I/O performance capability?

The PM1633a provides 200 KIOPS random read performance and 20 KIOPS random write performance. These specifications support transactional database workloads and applications requiring consistent random access patterns. The random read performance enables responsive access for database queries and other latency-sensitive operations.

What is the endurance rating and what does it mean?

The drive is rated for 1 DWPD (drive writes per day), meaning 480GB of data can be written daily to this drive. This endurance rating is designed for read-intensive enterprise workloads where write operations are less frequent than read operations, providing predictable performance and reliability for sustained daily operations.

What are the physical dimensions and weight?

The PM1633a measures 70 x 100 x 15 mm and weighs 140 grams. The compact 2.5 inch small form factor enables high storage density, allowing up to 384TB capacity in a 2U server configuration. This standardized form factor maintains compatibility with enterprise server chassis while delivering superior capacity per drive.

How does the 2.5 inch form factor benefit enterprise deployments?

The 2.5 inch SFF with 480GB capacity enables significant storage density improvements compared to traditional hard drives. Multiple drives can be consolidated into standard server form factors, reducing physical footprint, power consumption, and cooling requirements. This density advantage reduces operational overhead and enables efficient use of datacenter space.
