Compared with the previous-generation MZ7KM480HMHQ-00005, the Samsung SM883 MZ-7KH480A delivers a clear generational step up in endurance with 3 DWPD and 2,628 TBW, while maintaining full SATA 6Gb/s throughput at up to 540/520 MB/s for read/write operations. Its combination of Samsung V-NAND 3D MLC, 97,000/29,000 random read/write IOPS, and enterprise-grade write durability makes this 480 GB model a stronger choice for write-intensive boot, virtualization, and database edge workloads where predecessor-class SATA SSDs are more endurance-constrained.
With an endurance rating of 2628 TBW and 3 DWPD, the MZ-7KH480A is built for sustained write-intensive use far beyond normal client or boot-drive workloads. In practical terms, for typical OS, application, and logging usage, this level of endurance means the drive can serve reliably as a system disk for many years without endurance becoming a concern. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and metadata if power is suddenly interrupted, reducing the risk of corruption or incomplete writes. Its UBER of 1.0E-17 and 2 million-hour MTBF further indicate a high-integrity, enterprise-class design intended to minimize uncorrectable read errors and support dependable long-term operation.
1. The SATA 6Gb/s interface, paired with near-bus-limit sequential read performance, makes this drive an easy drop-in upgrade for existing enterprise servers that need faster data streaming without changing backplanes or controllers.
2. Its strong random read capability helps virtualized databases, metadata-heavy workloads, and boot-intensive environments serve far more small-block requests with less queue buildup.
3. A 3 DWPD endurance rating means the SSD is built for write-intensive enterprise use, supporting frequent full-drive rewrites in caching, logging, and transactional systems over its service life.
4. Samsung V-NAND 3D MLC provides a balanced enterprise mix of endurance, consistency, and power efficiency, making it better suited than consumer NAND for sustained datacenter duty cycles.
5. With typical latency around 100 µs, the drive helps reduce application response time variance, which is critical for predictable performance in OLTP, VDI, and latency-sensitive infrastructure.
Lower capacity: 240 GB Higher capacity: 960 GB At 480 GB, the MZ-7KH480A sits at the sweet spot of this enterprise SSD family. Compared with the 240 GB model, it offers much better headroom for OS images, logs, application growth, and overprovisioning, reducing the risk of early capacity pressure. Compared with the 960 GB version, it keeps acquisition cost and fleet budgeting more controlled while delivering broadly similar sequential and random performance for typical enterprise workloads. It is especially well suited for small-to-mid virtualization clusters, such as hosting boot and utility volumes for around 25 to 40 virtual machines.
Q: Is MZ-7KH480A suitable for a write-heavy database server?
A: Yes. The MZ-7KH480A is well suited for write-heavy database workloads, thanks to its 3 DWPD endurance, 2628 TBW rating, low 100 µs latency, and Samsung V-NAND 3D MLC flash.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 3 drive writes per day. With 480 GB capacity, that equals about 1.44 TB of writes daily across its specified warranty endurance period.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical in enterprise environments because it helps preserve in-flight data and metadata during unexpected power failures, reducing corruption risk.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for this SSD in performance-sensitive and write-intensive applications, as it balances speed, redundancy, and rebuild efficiency better than parity-based RAID in many server workloads.
