# Samsung 970 EVO Plus 250GB NVMe SSD Review (2026)

The Samsung 970 EVO Plus 250GB is the entry point of Samsung's most popular PCIe 3.0 NVMe line, squeezing 92-layer V-NAND and a Phoenix controller into a single-sided M.2 2280 card.

Quick answer: The Samsung 970 EVO Plus 250GB is a reliable PCIe 3.0 boot drive with proven Phoenix-level reliability and Samsung's software ecosystem, but the 2,300 MB/s write rating and small TurboWrite cache make it a poor pick for anyone who regularly moves large files. Buyers who need more than OS and a handful of applications should step up to the 500 GB or 1 TB model for higher sustained writes and double or quadruple the storage. The WD Blue SN570 250GB offers similar reads at a lower price point, though with lower endurance and no DRAM cache. For a pure OS drive in a legacy PCIe 3.0 system, the 970 EVO Plus 250GB remains a safe, well-supported choice.

## Performance

The Samsung 970 EVO Plus 250GB is rated for 3,500 MB/s sequential reads and 2,300 MB/s sequential writes within the TurboWrite cache. Once the 4 GB base cache and up to 9 GB of Intelligent TurboWrite are exhausted, direct-to-TLC writes settle around 400 MB/s, a steep cliff that matters for sustained transfers of more than ~13 GB. Random performance is rated at up to 250,000 read IOPS and 550,000 write IOPS, the lowest in the 970 EVO Plus family.

In everyday use as a boot drive, those cache limitations rarely surface. Game loads, application launches, and general OS responsiveness all benefit from the 3,500 MB/s read ceiling, which saturates the PCIe 3.0 x4 bus. Independent reviewers note that the 250 GB model trails the 1 TB variant meaningfully in write-heavy workloads, but reads are essentially identical across the range. For a pure OS-and-apps drive, the performance delta versus larger capacities is negligible in real-world latency.

## Endurance, TBW & Warranty

Samsung backs the 970 EVO Plus 250GB with a five-year limited warranty, terminated at 150 TBW (terabytes written), whichever comes first. At a typical consumer write workload of 20 GB per day, 150 TBW translates to over 20 years of use, so endurance is not a practical concern for a boot drive. The TBW rating applies per-drive; Samsung counts writes against the SMART attribute and will replace the drive under warranty if it fails the TBW threshold within the warranty window. Samsung's Magician software monitors remaining endurance, firmware updates, and drive health. RMA is handled through Samsung's service portal or the original retailer.

## Pros and Cons

**Pros:**

- 3,500 MB/s sequential reads saturate PCIe 3.0
- Samsung Phoenix controller with LPDDR4 DRAM
- Single-sided M.2 2280 fits laptops
- 150 TBW endurance for a 250 GB drive
- Five-year warranty with Samsung Magician support
**Cons:**

- Write speed drops to 400 MB/s after TurboWrite cache
- Only 250K random read IOPS at this capacity
- Small TurboWrite cache at 4 GB base
- Tighter capacity than most modern boot drives need


## Verdict

The Samsung 970 EVO Plus 250GB is a reliable PCIe 3.0 boot drive with proven Phoenix-level reliability and Samsung's software ecosystem, but the 2,300 MB/s write rating and small TurboWrite cache make it a poor pick for anyone who regularly moves large files. Buyers who need more than OS and a handful of applications should step up to the 500 GB or 1 TB model for higher sustained writes and double or quadruple the storage. The WD Blue SN570 250GB offers similar reads at a lower price point, though with lower endurance and no DRAM cache. For a pure OS drive in a legacy PCIe 3.0 system, the 970 EVO Plus 250GB remains a safe, well-supported choice.

## Frequently Asked Questions

### Is the Samsung 970 EVO Plus 250GB good for gaming?

As a boot or game-install drive the 970 EVO Plus 250GB performs well. The 3,500 MB/s read speed means game load times are competitive with any PCIe 3.0 NVMe SSD. The limitation is capacity rather than speed; most modern AAA titles occupy 50 to 150 GB on their own, so the drive fills quickly if used for more than a few games plus the OS.

### Is the Samsung 970 EVO Plus 250GB compatible with the PS5?

The PS5 requires PCIe 4.0 NVMe drives with a heatsink, so the PCIe 3.0 970 EVO Plus is not compatible. Sony's official requirements specify PCIe 4.0 x4 NVMe, 5,500 MB/s or higher sequential read recommended, and dimensions at or below 110 x 25 x 11.25 mm with heatsink. The 970 EVO Plus does not meet the interface or speed criteria.

### Does the Samsung 970 EVO Plus 250GB have a DRAM cache?

Yes, the 250 GB model includes 512 MB of Samsung LPDDR4 DRAM for the mapping table. This is half the DRAM on the 1 TB model (1 GB) and a quarter of the 2 TB model (2 GB), but it is sufficient for the 250 GB capacity's flash management needs.

### What is the TBW endurance of the Samsung 970 EVO Plus 250GB?

The 250 GB model is rated for 150 TBW (terabytes written) under Samsung's five-year warranty. At a typical consumer write workload of around 20 GB per day, this translates to approximately 20 years before reaching the rated limit, making endurance a non-issue for normal desktop or laptop use.

### Is the 250GB 970 EVO Plus slower than the 1TB model?

Yes, the 250 GB variant has meaningfully lower write specifications. It is rated at 2,300 MB/s sequential writes versus 3,300 MB/s on the 1 TB model, and 250,000 random read IOPS versus 600,000 IOPS. The TurboWrite cache is also smaller at 4 GB plus up to 9 GB Intelligent, compared to 6 GB plus up to 36 GB on the 1 TB. Read speeds are the same at 3,500 MB/s across all capacities.

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

The drive does not ship with a heatsink and most desktop motherboards' M.2 shields are sufficient. Samsung uses a nickel-coated controller and copper-foil back label for passive cooling. In tight laptop enclosures the drive throttles gracefully under sustained writes via Dynamic Thermal Guard. A dedicated aftermarket heatsink is not required for normal use.
