The Samsung PM1645A (MZ-ILT800C) is a strong fit for mixed enterprise workloads on SAS infrastructure, combining 12Gb/s dual-port-class reliability with 800 GB capacity, 3 DWPD endurance, 4,380 TBW, and balanced performance of 1,000/1,000 MB/s plus up to 230K/90K IOPS. As the PM1645A-generation successor to MZ-ILT800A, it offers a more current enterprise platform with a notably stronger endurance-to-performance profile for write-intensive virtualization, OLTP, and cache-tier deployments.
With an endurance rating of 4,380 TBW and 3 DWPD, the MZ-ILT800C is designed to handle sustained write-intensive enterprise workloads with a wide safety margin over its service life. In practical terms, for typical OS, application, logging, and virtualization usage, this level of endurance means it can serve reliably as a system or boot drive for many years without concern about normal write wear. The MZ-ILT800C also includes power loss protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and improving operational stability. Its enterprise-class UBER of 1.0E-17 and 2 million-hour MTBF indicate a very low probability of uncorrectable bit errors and strong long-term reliability, giving procurement teams added confidence for business-critical deployments.
1. The SAS 12Gb/s interface ensures seamless integration with dual-controller enterprise storage platforms, delivering dependable bandwidth and high availability for mission-critical infrastructure.
2. With 1000 MB/s sequential read performance, this drive accelerates large-block data access such as backup restoration, media streaming, and analytics dataset loading.
3. The 230,000K random read IOPS capability enables fast response under heavily concurrent workloads, making it well suited for virtualization clusters, OLTP databases, and metadata-intensive applications.
4. Rated at 3 DWPD, the drive can sustain intensive daily overwrites over its service life, supporting write-heavy enterprise environments with predictable endurance and lower replacement risk.
5. Built on Samsung V-NAND 3D TLC and delivering 100 µs typical latency, it balances enterprise-grade flash density with consistently quick access times for latency-sensitive business applications.
Lower-capacity reference: 400 GB Higher-capacity reference: 1.6 TB Within this enterprise SSD family, the 800 GB model sits at a practical sweet spot. Compared with the 400 GB version, it provides noticeably better space headroom for OS images, application binaries, logs, and moderate data growth, reducing early capacity pressure. Compared with the 1.6 TB option, it preserves nearly the same enterprise-class read/write and random IOPS behavior while keeping acquisition cost and fleet budgeting more controlled. It is especially well suited for mid-sized virtualization clusters, such as shared boot and application storage for about 40 to 60 virtual machines.
Q: Is MZ-ILT800C suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 4380 TBW, SAS 12Gb/s interface, and typical 100 µs latency, the MZ-ILT800C is well suited for write-intensive database and enterprise server workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 full drive writes per day. For an 800 GB SSD, that equals about 2.4 TB of writes daily, consistent with its 4380 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 unexpected outages, which is critical for preventing corruption and maintaining enterprise data integrity.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for performance-sensitive and write-heavy environments, while RAID 5 or 6 may suit capacity-focused deployments. The best choice depends on required performance, protection, and rebuild tolerance.
