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

The Samsung 970 EVO 1TB was Samsung's mainstream PCIe 3.0 flagship before the EVO Plus refresh, pairing 64-layer TLC with a Phoenix controller for 2,500 MB/s writes and 600 TBW endurance.

Quick answer: The Samsung 970 EVO 1TB is a reliable PCIe 3.0 NVMe SSD, but the 970 EVO Plus 1TB outperforms it in writes (3,300 vs 2,500 MB/s) and sustained TLC speed (1,700 vs 1,250 MB/s) at a similar price point. Unless the original EVO is substantially discounted, the Plus is the better choice. For new builds, PCIe 4.0 drives like the Samsung 980 Pro or WD Black SN850X offer double the bandwidth potential.

## Performance

Samsung rates the 1 TB 970 EVO at 3,500 MB/s sequential reads and 2,500 MB/s sequential writes inside the TurboWrite cache, with direct-to-TLC writes settling at approximately 1,250 MB/s. Random performance reaches 500,000 read IOPS and 450,000 write IOPS. The 42 GB Intelligent TurboWrite buffer is large enough that most consumer workloads never exceed it.

Independent reviewers found the 970 EVO 1TB to be a strong all-around performer at launch, though the 970 EVO Plus outperforms it in nearly every metric thanks to the newer NAND. The gap is most noticeable in write-heavy workloads, where the Plus sustains 1,700 MB/s after cache versus 1,250 MB/s on the original EVO. For read-heavy gaming workloads, the difference is minimal.

## Endurance, TBW & Warranty

Samsung covers the 970 EVO 1TB with a five-year limited warranty and a 600 TBW endurance rating. At a consumer-typical 20 GB of writes per day, 600 TBW translates to approximately 82 years of use. Samsung's Magician software provides real-time health monitoring, TBW tracking, and firmware updates. The warranty is honored through Samsung's service portal or the point of purchase.

## Pros and Cons

**Pros:**

- 3,500/2,500 MB/s sequential read/write
- 1 GB LPDDR4 DRAM cache
- 600 TBW endurance with five-year warranty
- 42 GB Intelligent TurboWrite buffer
- Single-sided M.2 2280 fits laptops
**Cons:**

- Superseded by the 970 EVO Plus in every metric
- TLC writes drop to 1,250 MB/s after cache fills
- 64-layer NAND older than EVO Plus 92-layer
- PCIe 3.0 caps reads at 3,500 MB/s


## Verdict

The Samsung 970 EVO 1TB is a reliable PCIe 3.0 NVMe SSD, but the 970 EVO Plus 1TB outperforms it in writes (3,300 vs 2,500 MB/s) and sustained TLC speed (1,700 vs 1,250 MB/s) at a similar price point. Unless the original EVO is substantially discounted, the Plus is the better choice. For new builds, PCIe 4.0 drives like the Samsung 980 Pro or WD Black SN850X offer double the bandwidth potential.

## Frequently Asked Questions

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

The 1 TB 970 EVO performs well for gaming with its 3,500 MB/s read speed and 42 GB TurboWrite cache. The 1 TB capacity holds the OS plus a substantial game library. The 970 EVO Plus offers higher write speeds, but for game loading the read performance is identical.

### What is the difference between the 970 EVO and 970 EVO Plus at 1TB?

The EVO Plus uses 92-layer TLC NAND versus 64-layer on the original EVO. This enables 3,300 MB/s writes on the Plus versus 2,500 MB/s on the original, and higher sustained TLC writes (1,700 vs 1,250 MB/s). Random read IOPS are also higher on the Plus at 600K versus 500K. Both use the same Phoenix controller.

### Is the Samsung 970 EVO 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. The 970 EVO is a PCIe 3.0 drive rated at 3,500 MB/s reads and does not meet Sony's requirements.

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

Samsung rates the 1 TB 970 EVO at 600 TBW (terabytes written) under its five-year warranty. At 20 GB of writes per day, this translates to approximately 82 years. At 50 GB per day, a heavy consumer workload, it would take roughly 33 years to exhaust the endurance rating.

### Does the Samsung 970 EVO 1TB need a heatsink?

No heatsink is included or required for normal use. Samsung uses a nickel-coated controller and copper-foil back label for passive heat dissipation. The Dynamic Thermal Guard firmware throttles performance if temperatures rise too high. Motherboard M.2 shields provide additional thermal margin.

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

Yes, all 970 EVO capacities use a single-sided M.2 2280 PCB, ensuring compatibility with laptops that require single-sided modules. Power consumption peaks at roughly 5.9 watts during writes and idles at 30 mW, suitable for mobile use.
