SAMSUNG PM1643a 3.84TB SAS 12Gb/s 2.5" internal SSD

Samsung PM1643a 3.84TB Enterprise SSD

The Samsung PM1643a is a 3.84TB internal solid-state drive built for enterprise servers and storage arrays. It uses a SAS 12 Gb/s interface and 3D TLC NAND to deliver consistent performance for mission-critical workloads. Enhanced power-loss protection with aluminum electrolytic capacitors helps safeguard data during unexpected outages. Optional TCG-compliant self-encryption and end-to-end data protection address strict security requirements.

Suited for virtual desktops web servers

This drive targets IT managers running virtual desktop infrastructures, web servers, email servers, ERP systems and relational databases where reliability and sequential throughput matter. The SAS 12 Gb/s interface supports 32 initiators with TCQ command sets up to 256 queue depth for heavy multi-workload environments. Workloads requiring a different physical interface or protocol should evaluate alternative drive types. The optional TCG Enterprise Specification Rev. 1.01 compliance fits regulated deployments.

SAS 12 Gb/s interface with 256 queue depth

The single specification that decides fit is the SAS 12 Gb/s interface combined with support for 32 initiators and TCQ command sets up to 256 queue depth. This determines whether the drive integrates with existing host bus adapters, backplanes and controller firmware in the target server or array. Compliance with SAS-3, SPL-3, SBC-4, SPC-5 and SAM-5 specifications ensures broad enterprise ecosystem compatibility. Verify the storage controller supports these standards before purchase.
