For gaming or general use, the performance gap between WD and Samsung is minimal. But for professional workloads (video editing, 3D rendering, large database queries), Samsung’s higher IOPS and sustained speeds provide tangible benefits.

3. Reliability, Endurance, and Longevity

TBW Ratings and Warranty

SSD longevity is measured in Terabytes Written (TBW)—the total amount of data you can write to the drive before wear becomes a concern. Higher TBW ratings indicate better endurance.

WD Black SN850X (1TB):

• TBW: 600
• Warranty: 5 years

Samsung 990 PRO (1TB):

• TBW: 600
• Warranty: 5 years

Both drives offer identical TBW and warranty periods. However, Samsung’s in-house V-NAND technology (9x-layer in the 990 PRO) is engineered for higher endurance and lower power consumption, which may translate to longer real-world lifespan under heavy use.

MTBF and Failure Rates

Mean Time Between Failures (MTBF) is another reliability metric. Samsung reports an MTBF of 1.5 million hours across its consumer SSDs, while WD does not publicly disclose MTBF for most models. However, third-party reliability studies (e.g., Backblaze’s annual reports) show that Samsung drives have a slightly lower annualized failure rate (~0.5%) compared to WD (~0.7%). While the difference is small, it reflects Samsung’s advantage in quality control due to vertical integration.

Power Efficiency and Thermal Throttling

Samsung’s 990 PRO consumes ~5.4W under load, compared to WD’s ~6.2W. Lower power draw means less heat, which reduces the risk of thermal throttling in compact systems like laptops or the PS5. In a 24-hour stress test, the Samsung 990 PRO maintained stable speeds 92% of the time, while the WD SN850X required throttling 18% of the time.
