Dell / Samsung PM1645 800GB SAS SSD

The Dell / Samsung 800GB 2.5" SAS 12Gbps Enterprise SSD (DPN: 0D9NCK, Model: MZ-ILT800A) is a high-performance solid-state drive designed for demanding datacentre and enterprise storage environments. Built on Samsung’s proven enterprise NAND architecture and typically associated with the PM1645-series platform, it delivers a strong balance of speed, reliability, and endurance for mission-critical workloads. Its 2.5" small form factor and hot-swap capability make it fully suitable for deployment in Dell PowerEdge servers and other SAS-enabled enterprise systems, where consistent 24/7 operation is required.

Engineered for mixed-use workloads, this SSD utilises a 12Gbps SAS-3 interface to provide excellent sustained throughput and low latency performance under heavy multi-user and virtualised conditions. It typically delivers sequential read speeds of up to around 1,000–1,250 MB/s and sequential writes approaching 900–1,200 MB/s, along with strong random I/O performance suitable for database hosting, virtual machine storage, caching layers, and transactional applications. The drive uses enterprise-grade 3D TLC NAND and supports 512e sector formatting for broad compatibility with RAID controllers and enterprise storage arrays.

Reliability is a core focus of this model, with features including full power-loss protection, advanced error correction, and a high endurance rating commonly around 3 drive writes per day (DWPD), making it suitable for sustained write-intensive workloads. Designed for continuous operation, it offers an MTBF in the multi-million-hour class and is optimised for integration into Dell-validated server environments. Overall, this SSD is a dependable enterprise-grade solution for organisations requiring stable, high-speed storage performance in virtualisation, database, and general-purpose datacentre applications.
