MZILT1T9HAJQ-000C3 Samsung PM1643 SAS 12GBPS 1.92TB Internal SSD

Understanding SAS-12GBPS Enterprise SSD

SAS (Serial Attached SCSI) SSDs represent the enterprise-grade storage solution designed for mission-critical applications requiring maximum reliability, performance consistency, and data integrity. Unlike consumer-grade SATA SSDs or high-speed NVMe drives, SAS SSDs like the Samsung PM1643 incorporate dual-port capability, allowing two hosts to connect to the same drive simultaneously for high-availability configurations. The MZILT1T9HAJQ-000C3 SAS-12Gbps interface delivers significantly higher throughput compared to SATA III's 6Gbps, with sustained performance under heavy workloads that would typically cause SATA drives to throttle.

Dual-Port Architecture for High Availability

The dual-port nature of SAS technology provides redundant pathways to storage data, ensuring continuous operation even if one host connection fails. This makes SAS SSDs ideal for RAID configurations, server clusters, and storage arrays where downtime is not an option. Each port operates independently at 12Gbps speeds, providing aggregate bandwidth that exceeds single-port solutions.

Enterprise Endurance and Reliability Features

SAS SSDs are engineered with enterprise workload endurance in mind, featuring advanced wear-leveling algorithms, power-loss protection, and enhanced error correction capabilities. The Samsung PM1643 incorporates these enterprise features to maintain data integrity across millions of read/write operations, far exceeding consumer SSD capabilities.

Detailed Performance Characteristics

Sequential Read and Write Performance

The Samsung MZILT1T9HAJQ-000C3 PM1643 delivers exceptional sequential performance with read speeds up to 1,100 MB/s and write speeds up to 1,000 MB/s. This high-throughput performance enables rapid data transfer for large file operations, database backups, and virtual machine migrations.

Random I/O Performance Metrics

For random operations, the drive achieves up to 180,000 IOPS (Input/Output Operations Per Second) for random reads and 60,000 IOPS for random writes at queue depth 128. This high random performance is critical for database applications, virtualization environments, and other transactional workloads where rapid access to small blocks of data is essential.

4K Random Read Performance

The 4K random read performance of 180,000 IOPS ensures responsive performance for read-intensive applications such as database query processing, web serving, and virtual desktop infrastructure. The consistent low latency maintained during these operations distinguishes enterprise SAS SSDs from consumer alternatives.

4K Random Write Performance

With 60,000 IOPS for 4K random writes, the PM1643 handles write-intensive operations efficiently. This performance level supports applications like transaction processing, logging, and real-time data analytics where write consistency is paramount.

Advanced Error Correction and Data Protection

Samsung implements sophisticated error correction code (ECC) algorithms capable of correcting multiple bit errors per page. Combined with end-to-end data protection, this ensures data integrity from the host interface through to the NAND media and back. The drive includes redundant pathing and failover capabilities inherent to the SAS architecture.

Power-Loss Protection (PLP)

Enterprise-grade power-loss protection circuitry ensures that in-flight data is protected during unexpected power interruptions. The PM1643 incorporates sufficient capacitor-based backup power to complete pending write operations and maintain data consistency, preventing corruption during power events.

Power Efficiency

Enterprise environments demand careful thermal management to maintain performance and reliability. The PM1643 incorporates advanced thermal throttling mechanisms that regulate performance based on temperature, preventing overheating while maintaining optimal operation. The drive typically consumes 5-7 watts during active operation and less than 1 watt during idle states, contributing to overall data center power efficiency.

Environmental Specifications

Designed for data center environments, the drive operates within a temperature range of 0°C to 70°C and can withstand operating shock up to 50G (2ms duration) and non-operating shock up to 1000G (1ms duration). These specifications ensure reliable operation in demanding server room conditions.
