Samsung PM1643 MZILT30THMLA delivers a standout combination of 30.72TB capacity, 12Gb/s SAS connectivity, and 56,064TBW endurance, making it an excellent fit for capacity-dense enterprise storage tiers, large virtualization clusters, and read-heavy database estates that still require consistent SAS reliability. Compared with the previous-generation MZILS15THMLH, it effectively doubles per-drive capacity to 30.72TB, enabling much higher rack-level storage density and lower slot, power, and infrastructure cost per terabyte without sacrificing enterprise-class performance of up to 2,100/1,700 MB/s and 400K/50K IOPS.
With an endurance rating of 56,064 TBW and 1 DWPD, the MZILT30THMLA is built to handle sustained daily write activity across its service life, making it far more than sufficient for typical enterprise system-boot, read-intensive, and mixed-use workloads. In practical terms, this level of endurance gives purchasers strong confidence that the drive can support long-term, write-heavy operation without endurance becoming a concern in normal deployment scenarios. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. Its UBER of 1.0E-17, together with a 2 million-hour MTBF, reflects a very high standard of data integrity and operational dependability expected in data center and business-critical environments.
1. The SAS interface ensures seamless integration with enterprise storage backplanes while providing the dual-port reliability and high-availability path redundancy required in mission-critical servers.
2. Its strong sequential read performance accelerates large-block workloads such as backup restores, media streaming, and data warehouse scans, helping shorten batch processing windows.
3. The high random read capability enables fast response for virtualization, OLTP databases, and metadata-heavy applications where many small requests must be served concurrently.
4. Built with Samsung V-NAND TLC and rated for daily full-drive rewrites, it offers a practical balance of flash density and write endurance for mixed-use enterprise deployments.
5. The low typical latency helps reduce application wait time, improving transaction responsiveness and delivering more predictable QoS under sustained load.
Lower capacity reference: 15.36TB Higher capacity reference: 61.44TB Capacity positioning analysis: Within this enterprise SSD family, 30.72TB is the sweet-spot capacity. Compared with 15.36TB, it provides much better space elasticity for denser consolidation, longer data retention, and more headroom for snapshots and overprovisioning, while keeping similar sequential and random performance behavior. Compared with 61.44TB, it usually delivers a more practical balance between acquisition cost, usable capacity, and risk concentration per drive. It is especially well suited for mid-scale virtualization or cloud nodes, such as a storage pool supporting about 180 to 260 mixed-workload virtual desktops or application instances.
Q: Is MZILT30THMLA suitable for a write-heavy database server?
A: MZILT30THMLA can support database workloads, but with 1 DWPD it is better suited for mixed-use or read-intensive environments rather than extremely write-heavy database servers.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 1 DWPD, meaning it can sustain one full 30.72TB drive write per day throughout its warranty period, aligned with its 56064TB TBW rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during sudden outages, reducing corruption risk in enterprise environments.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for this SSD when performance and redundancy are both important. RAID 5 or 6 may suit capacity-focused deployments, depending on workload priorities.
