Compared with the earlier MZ7LH240HAHQ-00005 ordering variant, the MZ7LH240HAHQ brings the PM883’s enterprise SATA platform into a streamlined 240 GB configuration with 341 TBW and 1.3 DWPD, giving system builders a more endurance-focused option for boot, logging, and read-cache tiers than typical client-grade SATA SSDs. Backed by Samsung 64-layer 3D TLC V-NAND, it combines near-interface-limit 550 MB/s read performance with 97,000 random-read IOPS, making it a stronger fit than same-class legacy SATA drives for dense server refreshes where predictable QoS and write durability matter.
With an endurance rating of 341 TBW and 1.3 DWPD, the MZ7LH240HAHQ is built to handle sustained daily write activity well beyond typical OS, boot, and application-drive workloads. In practical terms, for common system-disk use in servers, appliances, or industrial PCs, this level of endurance supports many years of reliable operation and can comfortably cover long-term deployment needs under normal write patterns. For enterprise reliability, this SSD includes power-loss protection, which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving system integrity. Its 1.0E-17 UBER and 2 million-hour MTBF further indicate strong data reliability and platform stability, giving procurement teams added confidence for business-critical use cases.
1. The SATA interface and near-bus-limit sequential read performance make this drive an easy drop-in upgrade for existing enterprise servers and storage arrays, accelerating OS boot, image loading, and bulk data access without requiring a platform refresh.
2. Its strong random read capability supports dense virtualization, OLTP databases, and metadata-heavy workloads by serving large volumes of small I/O requests with consistently fast application responsiveness.
3. The endurance rating is well suited for mixed-use enterprise environments, giving IT teams the confidence to sustain daily write activity over years of operation while reducing the risk of premature replacement.
4. Samsung’s 64-layer 3D TLC V-NAND balances cost, capacity, and reliability, enabling better rack-level storage efficiency for business-critical systems that need solid endurance without moving to a higher-cost media class.
5. The low typical latency helps minimize transaction wait time and tail-response delays, which is especially valuable for latency-sensitive applications such as real-time analytics, VDI, and high-concurrency service platforms.
Lower capacity reference: 120 GB Higher capacity reference: 480 GB In the Samsung PM883 family, the 240 GB model sits at a practical sweet spot. Compared with the 120 GB version, it gives noticeably more room for OS images, logs, swap, and application growth, reducing early capacity pressure. Compared with the 480 GB option, it preserves nearly the same enterprise-class SATA performance profile while keeping acquisition cost and fleet budget tighter. This makes 240 GB especially well suited for small to mid-scale virtualization clusters, such as hosting boot volumes for around 40 to 60 lightweight virtual machines.
Q: Is MZ7LH240HAHQ suitable for a write-heavy database server?
A: Yes, it is suitable for moderately write-intensive database workloads. With 1.3 DWPD, 341 TBW, low 145 µs latency, and enterprise Samsung V-NAND, it supports reliable server-side transactional performance.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1.3 full drive writes per day over its warranty period. For a 240 GB SSD, that equals about 312 GB of writes daily within 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 mapping tables during sudden outages, which is critical for preventing corruption and maintaining storage integrity in servers.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on the workload. RAID 1 is ideal for OS or critical data, while RAID 10 is preferred for databases needing strong redundancy and write performance.
