Compared with the previous MPN MZILG15THBLA-00B07, the MZILG15THBLA-00A07 moves to the PM1653 generation with Samsung 128-layer V-NAND and 24Gb/s SAS, delivering up to 4,300/2,400 MB/s and 800K/135K IOPS for higher bandwidth density and faster response in the same 15.36TB class. Its unique value is pairing that performance with 1 DWPD and 28,032 TBW, making it a strong choice for mission-critical SAN, database, and virtualization workloads that need better scalability than prior 12Gb/s SAS-era SSDs without sacrificing enterprise endurance.
With an endurance rating of 28,032 TBW and 1 DWPD, the MZILG15THBLA-00A07 is built to sustain very heavy write activity over its service life, making it well suited for always-on enterprise workloads. In typical use, this means it can serve reliably as a system or application drive for many years with ample write headroom, so procurement teams can deploy it with confidence in long-term durability. This model also includes power-loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving operational stability. Its enterprise-grade UBER of 1.0E-17, together with a 2.5 million hour MTBF, indicates an extremely low probability of unrecoverable read errors and strong overall reliability for business-critical environments.
1. The latest-generation SAS interface preserves dual-port high availability while giving enterprise arrays more bandwidth headroom for mission-critical shared storage.
2. Its strong sequential read performance accelerates large-block workloads such as backup restores, data lake scans, and media streaming from centralized storage.
3. The high random read capability sustains heavy OLTP, virtualization, and VDI traffic with faster response under deep queue pressure.
4. A one-drive-write-per-day endurance rating fits mixed-use enterprise deployments that need predictable lifespan for databases, hypervisors, and general-purpose storage tiers.
5. Built on advanced high-layer Samsung 3D TLC and paired with very low typical latency, it delivers a strong balance of capacity efficiency, power optimization, and consistently quick transaction handling.
Lower capacity reference: 7.68 TB Higher capacity reference: 30.72 TB Capacity positioning analysis: In this series, 15.36 TB is the sweet-spot capacity. Compared with the 7.68 TB model, it offers much better space headroom for data growth, longer refresh cycles, and higher consolidation efficiency without changing the expected enterprise-class sequential throughput or random IOPS profile. Compared with the 30.72 TB model, it usually delivers the best balance of acquisition cost, usable capacity, and predictable performance per drive. It is well suited for mid-scale virtualization clusters, such as supporting about 60 to 80 mixed-workload virtual machines or a compact all-flash database tier.
Q: Is MZILG15THBLA-00A07 suitable for a write-heavy database server?
A: It can support mixed or moderate write database workloads, but it is not ideal for very write-heavy servers. With 1 DWPD, it is better suited for read-intensive or balanced enterprise applications.
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 15.36 TB drive write per day over its warranty period, aligned with its 28,032 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 sudden power failure, which is critical for maintaining integrity, consistency, and reliability in enterprise environments.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for performance-sensitive databases, offering strong redundancy and low latency. For capacity-focused deployments, RAID 5 or RAID 6 may also be considered, depending on workload priorities.
