Compared with the previous-generation MZ3LO3T8HBLA, the 3.84 TB PM1743 advances to PCIe Gen5 x4 and Samsung 6th-Gen 128-layer V-NAND, delivering up to 14,000/7,100 MB/s and 2,500,000/250,000 IOPS for a clear generational gain in host bandwidth and read-intensive transaction performance within the same 1 DWPD enterprise class. It is a strong fit for latency-sensitive OLTP databases, large-scale virtualization, and real-time analytics nodes that need top-tier sequential read speed with enterprise endurance of 7,008 TBW.
With an endurance rating of 7008 TBW, the MZ-3LO3T80 is designed to absorb about 7.0 petabytes of total writes over its service life, which is far above the write volume of typical OS, boot, and general server workloads. In practical terms, for common system-disk or read-heavy enterprise use, this level of endurance can comfortably support many years of operation, while its 1 DWPD rating confirms it is built for consistent daily write activity. Its enterprise reliability profile is further strengthened by Power Loss Protection (PLP), which helps preserve in-flight data and prevent metadata corruption if power is suddenly interrupted. The 1.0E-17 UBER specification means an extremely low probability of unrecoverable bit errors during reads, giving procurement teams added confidence in data integrity for business-critical environments.
1. The PCIe Gen5 x4 interface, paired with ultra-high sequential bandwidth, accelerates large dataset streaming, checkpoint loading, and backup restore workflows in performance-critical servers.
2. Its exceptional random read capability sustains massive parallel I/O, helping databases, virtualization clusters, and AI inference platforms respond faster under heavy concurrency.
3. The 1 DWPD endurance rating provides predictable write sustainability for mixed enterprise workloads, reducing replacement frequency and supporting stable long-term TCO.
4. Samsung 6th-Gen 128-layer 3D TLC V-NAND balances density, power efficiency, and reliability, making it well suited for scale-out data center deployments that need both capacity and consistent performance.
5. The very low typical latency minimizes storage wait time, improving QoS and enabling faster transaction handling for latency-sensitive enterprise applications.
For the 3.84 TB enterprise SSD (MPN MZ-3LO3T80), the typical adjacent capacities in the same family are 1.92 TB as the next lower option and 7.68 TB as the next higher option. In most enterprise SSD series, these three capacities deliver broadly similar sequential read/write throughput and random IOPS, with differences mainly driven by endurance tier and interface rather than capacity alone. At 3.84 TB, this model sits in the sweet spot of the lineup. Compared with 1.92 TB, it gives much better headroom for VM growth, log expansion, and application bursts without forcing early drive replacement. Compared with 7.68 TB, it usually offers a more attractive cost-to-usable-capacity ratio while keeping enterprise-class performance essentially unchanged. It is best suited for mid-scale virtualization clusters, mixed database nodes, or compact hyperconverged deployments, such as hosting around 40-60 general-purpose virtual machines with comfortable operating margin.
Q: Is MZ-3LO3T80 suitable for a write-heavy database server?
A: MZ-3LO3T80 can support mixed-use and moderate write-intensive database workloads, but with 1 DWPD, it is not the best choice for extremely write-heavy servers requiring higher endurance margins.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This SSD is rated for 1 DWPD, meaning it can sustain one full 3.84 TB drive write per day over its warranty period, aligned with the 7008 TBW endurance specification.
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 outages, which is critical for maintaining data integrity and reducing corruption risk in enterprise systems.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for this SSD in performance-sensitive environments, as it balances speed, redundancy, and rebuild efficiency. RAID 1 or RAID 5 may also fit capacity-focused deployments.
