# Samsung 970 EVO Plus 1TB PCIe 3.0 NVMe SSD (2026)

The Samsung 970 EVO Plus 1TB is the capacity most reviewers benchmarked and the one that cemented this drive's reputation, delivering 3,300 MB/s writes and 600 TBW on Samsung's 92-layer V-NAND.

Quick answer: The Samsung 970 EVO Plus 1TB is arguably the best all-round PCIe 3.0 NVMe SSD Samsung produced in this generation, combining high sustained writes, large TurboWrite cache, and 600 TBW endurance at a capacity that fits most users' needs. Buyers doing sustained multi-hundred-GB transfers should look at the Samsung 970 Pro for its MLC-based consistent writes, and anyone building a PCIe 4.0 or 5.0 system should consider the 980 Pro or 990 Pro instead. For existing PCIe 3.0 platforms, the 970 EVO Plus 1TB remains one of the strongest picks available.

## Performance

Samsung rates the 1 TB 970 EVO Plus at 3,500 MB/s sequential reads and 3,300 MB/s sequential writes within the TurboWrite SLC cache, with 600,000 random read IOPS and 550,000 random write IOPS. The Intelligent TurboWrite cache scales up to 42 GB on this model, significantly larger than the 22 GB on the 500 GB model, which means most consumer workloads never exhaust it.

Once the cache fills, the drive writes directly to TLC at approximately 1,700 MB/s, which is fast enough that the step-down is barely noticeable in everyday use. Independent reviewers consistently found the 1 TB model trading blows with the more expensive Samsung 970 Pro in mixed workloads, sometimes exceeding it in real-world application tests and game load benchmarks. The only scenario where the 970 Pro retains a clear advantage is sustained writes of hundreds of gigabytes without pause, where the Pro's MLC architecture avoids the cache-exhaustion penalty entirely.

## Endurance, TBW & Warranty

Samsung covers the 970 EVO Plus 1TB with a five-year limited warranty, subject to a 600 TBW endurance rating. At a consumer-typical 20 GB of writes per day, 600 TBW translates to approximately 82 years of use. Even at a heavier 50 GB per day, the drive would take 33 years to reach the TBW limit. Samsung's Magician software provides real-time health monitoring, including remaining TBW percentage, and firmware updates can be applied in-place. Warranty claims are processed through Samsung's service portal or the point of purchase.

## Pros and Cons

**Pros:**

- 3,500/3,300 MB/s sequential read/write
- 600,000 random read IOPS at 1 TB
- 1 GB LPDDR4 DRAM cache
- 42 GB Intelligent TurboWrite buffer
- 600 TBW endurance with five-year warranty
- Sustained TLC writes hold at 1,700 MB/s
**Cons:**

- PCIe 3.0 caps reads at 3,500 MB/s
- No included heatsink
- SLC cache dependency for peak writes
- Newer PCIe 4.0 drives offer double the bandwidth


## Verdict

The Samsung 970 EVO Plus 1TB is arguably the best all-round PCIe 3.0 NVMe SSD Samsung produced in this generation, combining high sustained writes, large TurboWrite cache, and 600 TBW endurance at a capacity that fits most users' needs. Buyers doing sustained multi-hundred-GB transfers should look at the Samsung 970 Pro for its MLC-based consistent writes, and anyone building a PCIe 4.0 or 5.0 system should consider the 980 Pro or 990 Pro instead. For existing PCIe 3.0 platforms, the 970 EVO Plus 1TB remains one of the strongest picks available.

## Frequently Asked Questions

### Is the Samsung 970 EVO Plus 1TB good for gaming?

The 1 TB 970 EVO Plus is an excellent gaming drive for PCIe 3.0 systems. The 3,500 MB/s read speed ensures fast game loads, the 42 GB TurboWrite cache covers most install and patch writes without throttling, and the 1 TB capacity holds the OS plus a large game library. For PCIe 4.0 systems, the Samsung 980 Pro or 990 Pro would be faster alternatives.

### Is the Samsung 970 EVO Plus 1TB compatible with the PS5?

No, the PS5 requires a PCIe 4.0 NVMe M.2 SSD with recommended reads of 5,500 MB/s or higher and an installed heatsink. The 970 EVO Plus is a PCIe 3.0 drive rated at 3,500 MB/s reads and does not meet Sony's published requirements for the expansion slot.

### Does the Samsung 970 EVO Plus 1TB have a DRAM cache?

Yes, the 1 TB model includes 1 GB of Samsung LPDDR4 DRAM for the flash translation layer. This is double the 512 MB on the 250 GB and 500 GB models. The DRAM cache helps maintain consistent random IO performance and contributes to the drive's strong mixed-workload results.

### What is the TBW endurance of the Samsung 970 EVO Plus 1TB?

The 1 TB model is rated at 600 TBW (terabytes written) under Samsung's five-year warranty. At 20 GB of writes per day this translates to roughly 82 years. At 50 GB per day, a heavy consumer workload, it would take approximately 33 years. The endurance rating is not a practical concern for any normal consumer use pattern.

### How does the 970 EVO Plus compare to the 970 Pro?

The 970 EVO Plus uses TLC NAND with an SLC write cache, while the 970 Pro uses MLC NAND that writes directly at full speed without a cache dependency. In burst and mixed workloads the EVO Plus matches or sometimes exceeds the Pro thanks to its faster 92-layer NAND. The Pro wins in sustained writes beyond the cache, where it maintains 2,700 MB/s consistently versus the EVO Plus dropping to 1,700 MB/s.

### Does the Samsung 970 EVO Plus 1TB work in a laptop?

Yes, the 970 EVO Plus uses a single-sided M.2 2280 PCB across all capacities, including the 1 TB model. This means components sit on one side only, fitting slim laptops that require single-sided modules. Power draw peaks at 6 watts during writes, and the drive idles at 30 mW, making it suitable for mobile systems.

### Does the Samsung 970 EVO Plus need a heatsink?

No heatsink is included and none is required for normal desktop or laptop use. Samsung uses a nickel coating on the Phoenix controller and a copper-foil layer on the back label for passive heat dissipation. Under sustained writes the Dynamic Thermal Guard algorithm throttles speed to keep temperatures safe. Motherboard M.2 heatsinks or shields provide additional margin in hot cases.
