In the realm of solid-state drives (SSDs), two giants stand out: the Samsung 980 Pro and the WD Black SN770. Both boast impressive specs and cutting-edge technology, making them top contenders for high-performance computing needs. In this comprehensive comparison, we delve into the key differences between the Samsung 980 Pro SSD and the WD Black SN770, helping you make an informed decision for your next storage upgrade.
Sequential Read and Write Speeds
Sequential read and write speeds are crucial for tasks that involve large file transfers, such as video editing, gaming, or data analysis. The Samsung 980 Pro excels in this area, boasting read speeds of up to 7,000 MB/s and write speeds of up to 5,000 MB/s. The WD Black SN770, while still impressive, falls slightly behind with read speeds of up to 5,150 MB/s and write speeds of up to 4,800 MB/s.
Random Read and Write Speeds
Random read and write speeds are equally important for everyday tasks like loading operating systems, applications, and games. The Samsung 980 Pro again takes the lead with random read speeds of up to 1,000,000 IOPS and random write speeds of up to 1,000,000 IOPS. The WD Black SN770 delivers respectable random speeds of up to 700,000 IOPS for both reads and writes.
Endurance and Reliability
Endurance refers to the lifespan of an SSD and is measured in terabytes written (TBW). The Samsung 980 Pro offers exceptional endurance with a TBW rating of 1,200 TBW for the 1TB model and 2,400 TBW for the 2TB model. The WD Black SN770, on the other hand, has a TBW rating of 600 TBW for the 1TB model and 1,200 TBW for the 2TB model. While both drives provide ample endurance for most users, the Samsung 980 Pro has a clear advantage in this regard.
Form Factor and Capacity
Both the Samsung 980 Pro and the WD Black SN770 come in the M.2 2280 form factor, making them compatible with most modern laptops and desktops. The Samsung 980 Pro is available in capacities ranging from 250GB to 2TB, while the WD Black SN770 offers capacities from 500GB to 2TB. The wider capacity options of the Samsung 980 Pro make it a better choice for users who require large storage space.
Price and Value
The Samsung 980 Pro and the WD Black SN770 are priced similarly, with the 1TB models of both drives retailing around $150. For the price, the Samsung 980 Pro offers superior sequential and random read and write speeds, as well as higher endurance. However, the WD Black SN770 provides a more affordable option with still-impressive performance and a decent TBW rating.
Which SSD Is Right for You?
Choosing between the Samsung 980 Pro SSD and the WD Black SN770 depends on your specific requirements. If you prioritize blazing-fast speeds, high endurance, and ample capacity, the Samsung 980 Pro is the clear winner. However, if you’re on a tighter budget and value affordability over absolute performance, the WD Black SN770 is a solid choice.
Additional Considerations
Cache Size: The Samsung 980 Pro features a larger cache size (1GB or 2GB) compared to the WD Black SN770 (512MB or 1GB). A larger cache improves responsiveness and reduces latency.
Controller: The Samsung 980 Pro uses Samsung’s proprietary Elpis controller, while the WD Black SN770 employs a Phison E18 controller. Both controllers are known for their high performance and reliability.
NAND Type: Both drives utilize TLC (Triple-Level Cell) NAND flash memory, which offers a balance of performance and cost-effectiveness.
