Compared with the previous-generation MZILS3T8HMLH, the PM1643 MZILT3T8HALS-000C3 moves to a newer TLC V-NAND platform and raises 12Gb/s SAS performance to up to 2100/1700 MB/s with 400,000/45,000 IOPS, giving a clear uplift in throughput and mixed-workload responsiveness at the same 3.84TB class. Its 1 DWPD endurance and 7008 TBW make it a stronger choice for virtualized databases, enterprise RAID tiers, and read-heavy transactional environments that need higher usable capacity and predictable SAS reliability than the prior generation.
With an endurance rating of 7008 TBW and 1 DWPD, the MZILT3T8HALS-000C3 is designed to handle writing its full capacity once per day across the warranty period, which is more than sufficient for typical enterprise boot, OS, and general application workloads. In practical terms, under normal system-disk or mixed read/write usage, this level of endurance supports many years of stable operation with substantial write headroom, giving procurement teams confidence in long-term deployment. For enterprise reliability, built-in Power Loss Protection (PLP) helps preserve in-flight data and protects metadata integrity during unexpected power interruptions, reducing the risk of corruption or unplanned downtime. Its UBER of 1.0E-17 indicates an extremely low unrecoverable bit error rate, and when combined with the 2 million-hour MTBF, it reflects a storage device engineered for dependable data integrity in business-critical environments.
1. The SAS interface brings enterprise-grade compatibility, dual-port high availability, and predictable performance in mission-critical storage arrays.
2. With sequential reads up to 2100 MB/s, the drive accelerates large-scale data scans, backup restores, and analytics jobs that depend on fast streaming throughput.
3. Its 400K random-read IOPS capability helps databases, virtualized clusters, and VDI environments sustain responsive access under heavy concurrent workloads.
4. Rated at 1 DWPD, this SSD is built for daily full-drive rewrites over its service life, making it a solid fit for mixed-use enterprise deployments.
5. TLC V-NAND paired with 90 µs typical latency delivers a strong balance of cost efficiency, flash density, and low-response-time performance for mainstream transactional applications.
Lower reference capacity: 1.92TB Higher reference capacity: 7.68TB In this SSD family, the 3.84TB model sits at the sweet spot for mainstream enterprise deployment. Compared with the 1.92TB version, it offers much more headroom for OS images, application growth, and data buffering, reducing early capacity pressure. Compared with the 7.68TB option, it delivers a better balance of acquisition cost, usable capacity, and near-identical enterprise performance characteristics. This makes 3.84TB especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for about 40 to 60 business workloads.
Q: Is MZILT3T8HALS-000C3 suitable for a write-heavy database server?
A: It can support database workloads, but with 1 DWPD it is better suited to mixed-use or read-intensive environments than highly write-heavy database servers with sustained, aggressive daily write activity.
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 handle approximately one full 3.84TB drive write per day over the warranty period, consistent with its 7008TB 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 metadata during unexpected power failure, which is critical for maintaining data integrity and enterprise application stability.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on your priority. RAID 10 is preferred for best performance and redundancy, while RAID 5 or RAID 6 may suit capacity-focused enterprise deployments.
