The Samsung 840 EVO 500GB (MZ7TE500HMHP) stands out in the SATA 6Gb/s class by pairing cost-efficient 19nm 3-bit MLC (TLC) NAND with near-interface-limit 540/520 MB/s sequential performance and strong 94,000/35,000 IOPS responsiveness, making it a well-balanced choice for client boot drives, VDI images, and read-centric application storage. Compared with the previous-generation MZ-7TD500, it delivers a clear generational uplift in write throughput and burst responsiveness while maintaining practical endurance at 72 TBW, giving engineers a better performance-per-dollar option for mainstream upgrade cycles.
With an endurance rating of 72 TBW and 0.16 DWPD, the MZ7TE500HMHP is well suited for read-focused and light-write workloads such as OS boot, office applications, thin clients, and general-purpose business PCs. In practical terms, that equals about 20 GB of writes per day for 10 years, so under typical system-drive usage it can deliver long, stable service with ample endurance margin. From a reliability perspective, the drive is rated at 1.5 million hours MTBF and an UBER of 1.0E-15, meaning the probability of an unrecoverable bit error is very low and aligned with standard enterprise-class data integrity expectations. This model does not include power-loss protection (PLP), so it is best deployed in systems with stable power or upstream backup power where in-flight write protection during sudden outages is not a primary requirement.
1. The SATA interface enables drop-in deployment across mainstream enterprise servers and storage arrays, making it ideal for cost-sensitive refresh projects without changing existing backplanes or cabling.
2. Its sustained sequential read performance helps accelerate boot storms, backup restores, and large file access in read-heavy virtualized and content delivery environments.
3. Strong random read capability supports fast response for OLTP databases, VDI login bursts, and metadata-intensive workloads where small-block access dominates.
4. With modest write endurance, this drive is best suited to read-centric enterprise use cases such as boot volumes, web serving, reference data, and analytics tiers with limited daily rewrites.
5. Samsung’s TLC NAND, paired with very low typical latency, delivers a balanced mix of flash density and responsive service times for predictable application performance at scale.
Lower capacity reference: 250GB Higher capacity reference: 1TB In this series, the 500GB MZ7TE500HMHP sits in the sweet spot for mainstream enterprise deployment. Compared with the 250GB option, it gives noticeably better headroom for OS images, application growth, logs, and overprovisioning, reducing early capacity pressure. Compared with the 1TB model, it preserves nearly the same class of sequential and random performance while keeping acquisition cost and fleet budgeting under tighter control. This makes 500GB especially well suited for mid-scale virtualization clusters, such as shared boot and application storage for around 40 to 60 light-to-medium workload virtual machines.
Q: Is MZ7TE500HMHP suitable for a write-heavy database server?
A: Not ideally. With 0.16 DWPD and 72 TBW, this 500GB SATA SSD is better suited for read-intensive or mixed workloads rather than write-heavy database server environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Its rated endurance is 0.16 drive writes per day, meaning about 16% of the full 500GB capacity can be written daily on average during the warranty period.
Q: Does it include power loss protection (PLP) and why is that critical?
A: No, it does not include PLP. This matters because unexpected power loss can cause in-flight data loss or metadata corruption, especially in transactional or cache-sensitive applications.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is generally recommended for better redundancy and steady performance. Since this model lacks PLP, avoid relying on it alone for critical data protection.
