Product Overview
The Samsung PM1643a is an enterprise-grade 2.5-inch SAS 12Gb/s solid-state drive delivering an industry-leading 30.72TB of storage capacity in a compact form factor. Built on Samsung V-NAND flash technology and compliant with the SAS-3/SPL-3/SBC-4/SPC-5/SAM-5 specification suite, the PM1643a is purpose-engineered for read-intensive, data-intensive enterprise workloads including large-scale databases, virtualized environments, cloud infrastructure, and high-capacity data center deployments. The drive features dual-port SAS connectivity for redundant path access, hardware-based power loss protection (PLP) using onboard capacitors, end-to-end data protection, TCG Enterprise encryption support, and ECC (Error-Correcting Code) technology — delivering the reliability, availability, and serviceability (RAS) demanded by mission-critical storage environments.
