The Samsung 860 EVO 500GB (MZ-76E500E) is a well-balanced SATA 6.0 Gbps SSD that pairs Samsung V-NAND 3-bit TLC with near-interface-limit performance—up to 550/520 MB/s sequential and 98,000/90,000 IOPS random—while maintaining a solid 300 TBW endurance profile for client and mixed-use upgrade deployments. Compared with the previous MZ-76E500B/AM, this revision delivers a more mature endurance-and-performance balance, making it the stronger choice for sustained desktop, notebook, and light workstation workloads where long-term write tolerance matters as much as peak SATA speed.
With an endurance rating of 300 TBW, this 500GB SSD can sustain a total of 300 terabytes of host writes over its usable life, which is more than sufficient for typical OS, office, and general business workloads. In practical terms, if it is used as a system drive with around 20–30GB of writes per day, it can comfortably support roughly 10 years or more of normal use before reaching its rated write limit. From a reliability perspective, the specified UBER of 1.0E-15 means the drive is designed for a very low uncorrectable bit error rate, helping ensure dependable data reads in day-to-day operation. This model does not include power-loss protection (PLP), so while it is suitable for standard client and boot-drive scenarios, applications with frequent unexpected power interruptions or write-critical transactions should use proper system-level power protection or consider a PLP-equipped SSD.
1. The SATA interface enables straightforward drop-in deployment across legacy enterprise servers and storage arrays, making fleet refreshes faster and more cost-efficient without platform redesign.
2. Its strong sequential read performance accelerates backup restores, VM image loading, and large-file access in read-heavy business workloads.
3. The high random read capability supports dense virtualized environments and metadata-intensive applications by keeping response times stable under heavy concurrent access.
4. With an endurance profile suited to light-to-moderate write cycles, it is a practical fit for boot, read-centric database, content delivery, and analytics tiers where capacity efficiency matters more than intensive rewriting.
5. Samsung V-NAND TLC combined with very low typical latency helps deliver predictable QoS and fast application responsiveness, which is valuable for transactional systems and latency-sensitive enterprise services.
Lower capacity reference: 250 GB Higher capacity reference: 1 TB Within this series, the 500 GB model sits at the sweet spot for mainstream enterprise-style deployments. Compared with the 250 GB version, it offers much better headroom for OS images, logs, patch growth, and application data, reducing the risk of early capacity pressure. Compared with the 1 TB option, it delivers nearly the same everyday sequential and random performance while keeping acquisition cost and fleet-wide budget under tighter control. It is especially well suited for small to mid-sized virtualization clusters, such as hosting boot and utility volumes for about 40 to 60 light-duty virtual machines.
Q: Is MZ-76E500E suitable for a write-heavy database server?
A: The MZ-76E500E is generally not ideal for write-heavy database servers. With 0.33 DWPD, 300 TBW, and TLC NAND, it is better suited for read-heavy or mixed everyday workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on its 0.33 DWPD rating, this SSD can sustain about one-third of a full drive write per day over its warranty period, which equals roughly 165 GB of writes daily.
Q: Does it include power loss protection (PLP) and why is that critical?
A: No, the MZ-76E500E does not include power loss protection. PLP is critical in server or transactional environments because it helps prevent in-flight data loss during unexpected power failures.
Q: What RAID level is recommended for this SSD?
A: For this SSD, RAID 1 or RAID 10 is typically recommended for better redundancy and stable performance. These levels are preferable for business use, especially since the drive lacks PLP.
