Samsung 980 PRO 1000GB

SSD Description

The Samsung 980 PRO utilizes the proprietary Elpis controller, fabricated on an 8nm process designed to optimize power efficiency while saturating the PCIe 4.0 interface. This architecture is supported by 1GB of LPDDR4 DRAM and Samsung’s 6th Generation (V6) 1xx-layer 3D TLC V-NAND. The model marks a pivot for the PRO line, transitioning from the 2-bit MLC NAND used in the predecessor 970 PRO to a 3-bit TLC design relying on SLC caching for peak performance. Field notes indicate the Elpis controller runs thermally dense; the drive uses a nickel coating on the controller package and a copper-embedded heat spreader label on the back, and active cooling is recommended for sustained workloads to prevent thermal throttling. Early firmware versions preceding 5B2QGXA7 had an anomaly that could lead to premature failure or read-only lock states; verifying and updating firmware via Samsung Magician is advised.

Hardware Alternatives

• WD Black SN850: matches the 980 PRO’s tier and generally offers slightly higher sequential write saturation
• Seagate FireCuda 530: a high-end reference design alternative (Phison E18 + Micron B47R) that often exceeds the 980 PRO in sustained sequential write throughput and endurance
• Kingston KC3000: another E18-based high-end alternative that typically offers stronger sustained sequential write performance and higher endurance, while the 980 PRO can hold an advantage in low queue-depth random read latency
