# Samsung 980 Pro 250GB PCIe 4.0 NVMe SSD (2026)

The Samsung 980 Pro 250GB is the entry point into Samsung's PCIe 4.0 flagship line, trading peak throughput for a lower cost of admission that still outpaces any SATA or PCIe 3.0 drive.

Quick answer: The Samsung 980 Pro 250GB makes sense as a compact OS or boot drive for a system that already has bulk storage elsewhere. Its PCIe 4.0 interface delivers responsive load times and snappy day-to-day performance that no SATA drive can match. Buyers planning to install large game libraries or work with big media files on this drive alone should step up to the 500 GB or 1 TB variant, which doubles or triples the TurboWrite cache and nearly doubles the sustained write speed. At the 250 GB capacity specifically, the WD Black SN850X 250 GB is a credible alternative with similar PCIe 4.0 throughput. The 980 Pro 250GB remains a competent entry in Samsung's flagship line, but its value proposition is weaker than the larger capacities in the same family.

## Performance

Samsung rates the 980 Pro 250GB at up to 6,400 MB/s sequential reads and 2,700 MB/s sequential writes over the PCIe 4.0 x4 bus. Random performance peaks at 500,000 read IOPS and 600,000 write IOPS at queue depth 32. Low-latency queue-depth-one performance is rated at 22,000 read IOPS and 60,000 write IOPS, which is competitive with other high-end NVMe drives at this capacity.

The drive uses Samsung's Intelligent TurboWrite 2.0 SLC caching, with a 4 GB static cache that can expand up to 49 GB dynamically from unused capacity. Once the cache is exhausted, writes drop to native TLC speed, which hovers around 500 MB/s on the 250 GB model. For a boot drive handling OS-level writes and application installs, the cache rarely fills under normal use. Sustained large-file transfers will feel the drop, though. Independent reviewers consistently place the 980 Pro family near the top of PCIe 4.0 drives in real-world game-load and application-latency tests, but note that the 250 GB trails the 1 TB and 2 TB by a wide margin in sequential write benchmarks.

## Endurance, TBW & Warranty

Samsung rates the 980 Pro 250GB at 150 TBW (terabytes written) over a five-year warranty period. That works out to roughly 0.3 drive writes per day, or about 82 GB of writes per day for five years straight. For a boot-drive workload dominated by reads and small writes, endurance is unlikely to be a practical concern. Samsung cites internal data from over 660,000 field SSDs showing that 99% of users write fewer than 156 TB over five years, well within the 150 TBW envelope. The drive also carries an MTBF rating of 1.5 million hours, a population-level reliability metric rather than a per-drive guarantee. If the drive fails within warranty, Samsung handles replacement directly through its RMA process.

## Pros and Cons

**Pros:**

- 6,400 MB/s sequential reads on PCIe 4.0
- 512 MB LPDDR4 DRAM for FTL mapping
- Single-sided M.2 2280 fits laptops and PS5
- AES 256-bit hardware encryption
- Samsung Magician software suite
- 5-year warranty with direct RMA
**Cons:**

- 2,700 MB/s writes, lowest in the 980 Pro range
- Native TLC writes drop to roughly 500 MB/s
- Only 150 TBW endurance
- 250 GB fills up fast as a modern game drive
- Better value per GB at 500 GB and 1 TB

## Frequently Asked Questions

### Is the Samsung 980 Pro 250GB good for gaming?

Yes, for loading games the 980 Pro 250GB performs well thanks to its PCIe 4.0 interface and responsive random-read performance. The 6,400 MB/s sequential read speed and 500,000 read IOPS translate to fast game-load times. The limitation is capacity: 250 GB holds the operating system plus only a handful of modern titles, which fill 80 to 150 GB each. If gaming is the primary use case, the 1 TB model offers a better balance of speed and storage space.

### Is the Samsung 980 Pro 250GB compatible with the PS5?

Yes. The PS5 requires an M.2 NVMe SSD with PCIe 4.0 support and recommends at least 5,500 MB/s sequential reads. The 980 Pro 250GB exceeds that threshold at 6,400 MB/s. The single-sided PCB keeps the drive within Sony's 11.25 mm height limit (including heatsink). Sony does not publish a model-specific compatibility list, but the 980 Pro meets all published requirements. A heatsink is required for PS5 installation and is not included with the bare drive.

### Does the Samsung 980 Pro 250GB have DRAM?

Yes. The 250 GB model includes 512 MB of Samsung LPDDR4 DRAM, which stores the flash translation layer mapping tables. This is a true DRAM cache, not the host-memory buffering (HMB) approach used by some DRAM-less drives. The DRAM contributes to consistent random-read and write latency, especially under mixed workloads. Larger 980 Pro capacities use more DRAM: 1 GB on the 1 TB and 2 GB on the 2 TB.

### What is the TBW endurance of the Samsung 980 Pro 250GB?

The 980 Pro 250GB is rated at 150 TBW (terabytes written) over its five-year warranty. At a typical consumer write workload of 20 to 50 GB per day, the drive would last decades before hitting the TBW ceiling. Samsung's own field data shows 99% of users write fewer than 156 TB over five years, meaning 150 TBW covers the vast majority of real-world use. Higher capacities in the 980 Pro line carry substantially more TBW: 300 TB for the 500 GB, 600 TB for the 1 TB, and 1,200 TB for the 2 TB.

### Is the Samsung 980 Pro 250GB slower than the 1TB model?

Substantially. The 250 GB variant writes at up to 2,700 MB/s versus 5,000 MB/s on the 1 TB, and its random IOPS ratings are roughly half: 500 K / 600 K read/write versus 1 M / 1 M on the 1 TB. After the TurboWrite cache fills, native TLC writes settle around 500 MB/s on the 250 GB compared to 2,000 MB/s on the 1 TB. Read speeds are closer at 6,400 MB/s versus 7,000 MB/s. The performance gap is real and measurable, though for OS boot and application launches the difference is less noticeable than in sustained transfers.

### Does the Samsung 980 Pro 250GB need a heatsink?

For desktop use, the copper foil on the drive label and nickel coating on the Elpis controller handle moderate workloads without additional cooling. Under sustained PCIe 4.0 transfers the controller can reach its thermal throttle point, so a motherboard-supplied M.2 heatsink is a sensible precaution. For PS5 installation, a heatsink is required by Sony and must keep total height below 11.25 mm. Many aftermarket M.2 heatsinks fit within that constraint.
