The Samsung PM1633a 3.84TB (MZILS3T8HMLH-000C3) is a high-capacity 12Gb/s SAS SSD tuned for read-centric enterprise workloads such as virtualization clusters, database replicas, and content delivery tiers, combining Samsung V-NAND 3D TLC with up to 1200/1000 MB/s sequential performance and 200,000/37,000 IOPS at a 1 DWPD endurance point. Compared with the previous MZILS3T8HCJM-00005, this “a” revision delivers a more current V-NAND platform and a stronger balance of usable 3.84TB density, 7008 TBW lifetime endurance, and sustained SAS throughput, making it a better fit for scale-out arrays that need predictable performance per drive slot.
With an endurance rating of 7008 TBW and 1 DWPD, the MZILS3T8HMLH-000C3 is designed to handle substantial daily write activity over its service life, making it well suited for sustained enterprise use. In typical workloads such as OS boot, application hosting, logging, or read-heavy server storage, this level of endurance is far beyond normal demand and can support many years of stable operation, including more than a decade of use as a system drive in many environments. Its enterprise-grade reliability is further strengthened by Power Loss Protection (PLP), which helps preserve in-flight data and prevents metadata corruption if power is suddenly interrupted. An UBER of 1.0E-17, together with a 2 million hour MTBF rating, indicates a very low probability of uncorrectable bit errors and supports the high data integrity and operational dependability expected in business-critical deployments.
1. The SAS interface brings proven dual-port enterprise connectivity and seamless integration with existing server and storage arrays, making it ideal for high-availability deployments.
2. Its strong sequential read performance speeds up full-dataset scans, backup recovery, and virtual machine image loading in data-center workflows.
3. The high random read capability helps OLTP databases, virtualization clusters, and metadata-heavy applications serve far more concurrent requests without becoming a storage bottleneck.
4. A one-drive-write-per-day endurance rating provides the write tolerance needed for steady enterprise duty cycles while keeping lifecycle costs predictable for read-centric and mixed workloads.
5. Samsung V-NAND 3D TLC, paired with very low typical latency, delivers a balanced mix of flash efficiency, consistent QoS, and fast application response for business-critical systems.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB At 3.84 TB, this SSD sits at the sweet spot of the family. Compared with the 1.92 TB model, it gives much better headroom for OS images, hot data, and future growth, reducing the risk of early capacity pressure. Compared with the 7.68 TB option, it keeps acquisition cost and rebuild domain more manageable while delivering essentially the same enterprise-class throughput and IOPS profile. This makes it especially well suited for mid-sized virtualization clusters, such as hosting boot and application volumes for about 40 to 60 business workloads.
Q: Is MZILS3T8HMLH-000C3 suitable for a write-heavy database server?
A: It can support mixed-use or moderately write-intensive database workloads, but with 1 DWPD, it is not ideal for extremely write-heavy environments. For heavier sustained writes, a higher-endurance SSD is recommended.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1 DWPD, meaning it can sustain one full 3.84 TB drive write per day over its warranty period, which aligns with its 7008 TBW endurance rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP helps preserve in-flight data and mapping tables during sudden power failure, which is critical for preventing corruption and maintaining enterprise data integrity.
Q: What RAID level is recommended for this SSD?
A: For database or virtualization workloads, RAID 10 is typically recommended for the best balance of performance and redundancy. If capacity efficiency matters more, RAID 5 or RAID 6 may be considered.
