Compared with MZ-76E1T0B/AM, the Samsung 860 EVO MZ-76E2T0 doubles usable capacity to 2 TB while maintaining up to 550/520 MB/s sequential performance and 98,000/90,000 IOPS, making it a stronger fit for higher-density SATA deployments without changing the platform. Its 1200 TBW endurance at 0.33 DWPD, backed by Samsung V-NAND 3-bit TLC, gives it a clear advantage for read-heavy virtualization, workstation boot/data tiers, and large content repositories that need predictable SATA performance with long service life.
With an endurance rating of 1200 TBW and 0.33 DWPD, the MZ-76E2T0 can sustain about 657 GB of writes per day over a 5-year equivalent usage period, which is well above the write volume of a typical OS boot drive or general office workload. In practical terms, for system-disk, read-heavy, and mainstream business applications, this level of endurance provides long service life and should comfortably support many years of normal operation. From a reliability perspective, the specified UBER of 1.0E-15 and MTBF of 1.5 million hours indicate a mature, dependable SSD platform suitable for standard business deployment. This model does not include power-loss protection (PLP), so it is best used in environments where sudden power interruption is mitigated by system-level safeguards such as UPS protection and where it is not relied on for write-critical caching or transactional data buffering.
1. The SATA interface, paired with near-bus-limit sequential read performance, enables straightforward drop-in upgrades for legacy enterprise servers while accelerating large file access, backups, and system boot operations without requiring a platform refresh.
2. Its strong random read capability helps virtualized environments and read-heavy databases respond faster under multi-user pressure, improving VM density and application responsiveness.
3. This endurance profile is well suited to read-centric enterprise workloads such as content delivery, analytics serving, and boot/storage tiers, where predictable reliability matters more than heavy daily overwrite capacity.
4. Samsung’s V-NAND 3-bit TLC balances flash density, power efficiency, and cost, giving data centers a practical way to scale capacity economically for mainstream enterprise deployments.
5. The low typical latency supports quicker transaction handling and more consistent QoS, which is valuable for latency-sensitive applications such as OLTP systems and interactive business services.
Lower-capacity reference: 1 TB, MPN MZ-76E1T0 Higher-capacity reference: 4 TB, MPN MZ-76E4T0 Typical performance across the series is broadly similar: up to about 550 MB/s sequential read, 520 MB/s sequential write, and around 98K/90K random read/write IOPS. At 2 TB, the MZ-76E2T0 sits in the sweet spot of the series. Compared with the 1 TB model, it offers noticeably better headroom for OS images, application stacks, logs, and data growth, reducing capacity pressure over the service cycle. Compared with the 4 TB version, it usually delivers the best balance of acquisition cost, usable capacity, and already-saturated SATA performance. It is well suited for a mid-sized virtualization cluster, such as hosting boot and application volumes for roughly 40 to 60 general-purpose virtual machines.
Q: Is MZ-76E2T0 suitable for a write-heavy database server?
A: The MZ-76E2T0 is generally better suited for read-intensive or mixed workloads. With 0.33 DWPD and TLC V-NAND, it is not the ideal choice for heavily write-intensive database server environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 0.33 drive writes per day, which means about one-third of its 2 TB capacity can be written daily over the warranty period, consistent with 1200 TBW endurance.
Q: Does it include power loss protection (PLP) and why is that critical?
A: No, this SSD does not include power loss protection. PLP is important in enterprise or transactional systems because it helps prevent in-flight data loss and metadata corruption during unexpected power failures.
Q: What RAID level is recommended for this SSD?
A: For most deployments, RAID 1 or RAID 10 is recommended to balance redundancy and performance. RAID 10 is especially preferable for business-critical workloads requiring better fault tolerance and consistent latency.
