# Samsung 980 250GB DRAM-less NVMe SSD Review (2026)

The Samsung 980 250GB is Samsung's entry-level NVMe SSD, dropping on-board DRAM in favour of a Host Memory Buffer design while still hitting 3,500 MB/s reads on PCIe 3.0.

Quick answer: The Samsung 980 250GB is a competent budget NVMe SSD that delivers PCIe 3.0 saturation on reads and competitive writes without on-board DRAM. It is best suited as a boot drive in modern systems with HMB support. Buyers who need more capacity or want DRAM-level consistency under heavy loads should consider the Samsung 970 EVO Plus 500GB or the WD Blue SN570 250GB as alternatives.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 250 GB |
| Interface | M.2 3.0 x 4 |
| Controller | Samsung Pablo |
| Memory type | Samsung TLC |
| DRAM cache | HMB |
| Sequential read | 3500 MB/s |
| Sequential write | 3000 MB/s |
| Random read IOPS | 500000 |
| Random write IOPS | 480000 |
| Endurance | 150 TBW |
| MTBF | 1.5 |
| Warranty | 5 years |

## Performance

Samsung rates the 980 250GB at 3,500 MB/s sequential reads and 3,000 MB/s sequential writes, with up to 500,000 random read IOPS and 480,000 random write IOPS. These figures assume HMB is active; without it, random performance drops significantly.

In real-world use, the 980 delivers consistent read speeds that saturate the PCIe 3.0 bus. Write speeds hold up well in typical consumer workloads, with an SLC write cache that buffers burst writes. Independent reviewers found the 980 competitive with DRAM-equipped PCIe 3.0 drives in sequential workloads, though random IO consistency can trail slightly in heavy multi-tasking scenarios where the HMB overhead becomes a factor. For gaming and general desktop use, the performance is indistinguishable from more expensive DRAM drives.

## Endurance, TBW & Warranty

Samsung backs the 980 250GB with a five-year limited warranty, subject to a 150 TBW endurance rating. At 20 GB of writes per day, 150 TBW translates to approximately 20 years of use, making endurance a non-concern for a boot drive. Samsung's Magician software monitors health, TBW consumption, and provides firmware updates.

## Pros and Cons

**Pros:**

- 3,500/3,000 MB/s sequential read/write at low cost
- Host Memory Buffer eliminates DRAM cost
- Single-sided M.2 2280 fits laptops
- Samsung Pablo controller with proven reliability
- 150 TBW with five-year warranty
**Cons:**

- No on-board DRAM; HMB requires compatible system
- 250 GB fills quickly for modern use
- Random IO trails DRAM drives under heavy load
- PCIe 3.0 interface caps at 3,500 MB/s


## Verdict

The Samsung 980 250GB is a competent budget NVMe SSD that delivers PCIe 3.0 saturation on reads and competitive writes without on-board DRAM. It is best suited as a boot drive in modern systems with HMB support. Buyers who need more capacity or want DRAM-level consistency under heavy loads should consider the Samsung 970 EVO Plus 500GB or the WD Blue SN570 250GB as alternatives.

## Frequently Asked Questions

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

The 980 250GB delivers 3,500 MB/s reads which ensures fast game load times comparable to any PCIe 3.0 NVMe drive. The 250 GB capacity is tight for a gaming setup, holding the OS and perhaps two to three AAA titles. For gaming-focused builds, the 500 GB or 1 TB model offers a better balance of capacity and price.

### What does DRAM-less HMB mean on the Samsung 980?

The Samsung 980 has no dedicated DRAM chip on the drive. Instead, it uses the NVMe Host Memory Buffer (HMB) feature to borrow a small amount of system RAM (typically around 32 MB) for the flash translation layer cache. This reduces cost while maintaining most of the performance of DRAM-equipped drives. HMB requires Windows 10 or later and a compatible motherboard BIOS.

### Is the Samsung 980 250GB 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 Samsung 980 is a PCIe 3.0 drive rated at 3,500 MB/s and does not meet Sony's requirements. Samsung's 980 Pro or 990 Pro are the PCIe 4.0 alternatives.

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

Samsung rates the 250 GB 980 at 150 TBW (terabytes written) under its five-year warranty. At a typical consumer write rate of 20 GB per day, this translates to approximately 20 years before reaching the endurance limit. The warranty period will typically be the binding constraint.

### Does the Samsung 980 need a heatsink?

No heatsink is included or required. Samsung uses a nickel-coated Pablo controller and copper-foil back label for passive heat dissipation. The Dynamic Thermal Guard firmware throttles performance if temperatures rise too high. The 980 runs cooler than many PCIe 4.0 drives, making motherboard M.2 shields more than sufficient.

### How does the Samsung 980 compare to the 970 EVO Plus?

The 980 is DRAM-less and uses HMB, while the 970 EVO Plus has dedicated LPDDR4 DRAM. The EVO Plus offers higher write speeds at most capacities (3,200 to 3,300 MB/s versus 3,000 MB/s) and better random IO consistency under heavy loads. The 980 costs less and runs cooler. For budget builds the 980 is sufficient; for performance-oriented builds the EVO Plus is the better choice.
