The Samsung 840 EVO 500GB (MZ-7TE500) stands out in the client SATA tier by pairing Samsung 19nm TLC with TurboWrite-class performance, delivering 540/520 MB/s throughput and a 150 TBW rating that makes it a strong fit for OS, productivity, and read-heavy workstation upgrades. Compared with the previous-generation MZ-7TD500BW, it raises sequential write speed from 250 MB/s to 520 MB/s—more than a 2x improvement—while also offering higher sustained responsiveness at the same 500 GB capacity.
With an endurance rating of 150 TBW and 0.3 DWPD, the MZ-7TE500 is well suited for typical client and light business workloads, where daily write volumes are relatively modest. In practical terms, it can comfortably serve as an OS or boot drive for many years under normal use, including routine office applications, software installation, updates, and general data access. For reliability, the specified UBER of 1.0E-15 means the drive is designed to maintain a very low rate of unrecoverable read errors, supporting dependable data reads in everyday operation. This model does not include power loss protection (PLP), so while it is a solid choice for standard environments with stable power, applications requiring protection against sudden power interruption during in-flight writes should consider systems with backup power or SSDs with PLP.
1. The SATA interface, paired with near bus-limit sequential throughput, enables straightforward drop-in upgrades for legacy enterprise servers while accelerating bulk data access such as boot images, backups, and content distribution.
2. Its strong random read capability helps VDI, OLTP, and metadata-heavy workloads return small-block data quickly, improving VM density and user responsiveness under parallel access.
3. The endurance profile is best suited to read-centric enterprise deployments, giving data centers a cost-efficient option for boot, caching, and content-serving tiers with limited daily write pressure.
4. Samsung’s planar TLC flash balances affordability and usable capacity, making it a practical choice for scale-out environments where $/GB matters more than write-intensive longevity.
5. The low typical access latency supports faster application response and steadier QoS, which is especially valuable for latency-sensitive lookup, indexing, and transactional read paths.
Lower reference capacity: 250 GB Higher reference capacity: 750 GB In this series, the 500 GB model sits at the sweet spot for balanced enterprise deployment. Compared with the 250 GB version, it gives much better headroom for OS images, application binaries, logs, and short-term data growth, reducing the risk of early capacity pressure. Compared with the 750 GB option, it preserves nearly the same practical performance profile while keeping acquisition cost and fleet-level spend under tighter control. It is best suited for small-to-mid virtualization clusters, such as hosting boot volumes for about 40 to 60 business application instances.
Q: Is MZ-7TE500 suitable for a write-heavy database server?
A: No. The MZ-7TE500 is better suited for read-focused or light mixed workloads. Its 0.3 DWPD, TLC NAND, and lack of PLP make it less ideal for write-heavy database environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on 150 TBW and 500 GB capacity, it supports about 300 full drive writes total. If you assume a 5-year warranty, that equals roughly 0.16 full writes per day.
Q: Does it include power loss protection (PLP) and why is that critical?
A: No, it does not include PLP. That matters because PLP helps protect in-flight data and mapping tables during sudden power failure, reducing corruption risk in enterprise or transactional workloads.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is generally recommended for this SSD, especially for reliability-focused deployments. Avoid parity-heavy RAID like RAID 5/6 in write-intensive scenarios due to endurance and PLP limitations.
