Samsung 980 2TB DRAM-less NVMe SSD Review
The Samsung 980 2TB is the highest-capacity model in Samsung's DRAM-less NVMe lineup, pairing 128-layer V-NAND with the Pablo controller for 3,500 MB/s reads and 488 TBW endurance.
The 2 TB Samsung 980 uses the Pablo controller with 128-layer (V6) Samsung TLC V-NAND and the Host Memory Buffer (HMB) architecture, borrowing system RAM for the flash translation layer instead of using dedicated DRAM. The 2 TB model uses denser 512Gb dies to fit enough flash on the single-sided M.2 2280 PCB.
Samsung rates the 2 TB model at 3,500 MB/s sequential reads and 3,000 MB/s sequential writes, with 500,000 random read IOPS and 480,000 random write IOPS. Endurance is 488 TBW with a five-year warranty. All capacities in the 980 range use a single-sided PCB, ensuring laptop compatibility.
This capacity is for users who want a single-drive solution for OS, games, creative work, and media on a budget. The main trade-off versus the 970 EVO Plus 2TB is the lack of DRAM, which affects random IO consistency under sustained multi-tasking. The Samsung 970 EVO Plus 2TB offers 3,300 MB/s writes with DRAM but costs more. Competitors include the 2 TB WD Blue SN570 and Kingston NV2.

- Samsung 980 2 TB (this drive): 3,500 MB/s read, 3,000 MB/s write
- ADATA SX 8800 Pro 512 GB: 3,500 MB/s read, 2,700 MB/s write
- ADATA SX 8800 Pro 1 TB: 3,500 MB/s read, 2,700 MB/s write
- ADATA XPG Spectrix S40G RGB 256 GB: 3,500 MB/s read, 3,000 MB/s write
- ADATA XPG Spectrix S40G RGB 512 GB: 3,500 MB/s read, 3,000 MB/s write
In sequential workloads, the 2 TB model matches the rest of the 980 family. The extra NAND dies provide a slight edge in sustained random writes compared to the smaller capacities. The HMB mechanism handles the mapping table for the 2 TB capacity without issue on modern systems with sufficient RAM. Independent reviewers found the 2 TB model to be the best performer in the 980 range, as the additional dies improve garbage collection efficiency.
🖥️ Endurance and warranty
Samsung covers the 980 2TB with a five-year limited warranty and a 488 TBW endurance rating. At 20 GB of writes per day, 488 TBW translates to approximately 67 years of use. Samsung's Magician software provides health monitoring, TBW tracking, and firmware updates.

Conclusion
The Samsung 980 2TB is a high-capacity DRAM-less NVMe SSD that delivers consistent PCIe 3.0 performance at a competitive price. The 2 TB capacity makes it a viable single-drive solution for budget builds. Users who need DRAM-level consistency or higher writes should consider the Samsung 970 EVO Plus 2TB, which offers 3,300 MB/s writes with dedicated DRAM at a higher cost. For budget-oriented builders on PCIe 3.0 platforms, the 980 2TB is a practical choice.
