When it comes to high-performance storage solutions, Samsung SSDs are among the most popular choices on the market. Two models that often get compared are the Samsung 870 EVO SATA III SSD and its predecessor, the Samsung 860 EVO SATA III SSD. While both drives share some similarities, there are key differences that set them apart.

Performance Comparison

The Samsung 870 EVO SATA III SSD boasts improved performance over its predecessor, with sequential read and write speeds of up to 560 MB/s and 530 MB/s, respectively. In contrast, the Samsung 860 EVO SATA III SSD has sequential read and write speeds of up to 550 MB/s and 520 MB/s, respectively. This means that the 870 EVO offers a slight edge in terms of raw performance.

Controller and Memory

The Samsung 870 EVO SATA III SSD features a newer controller, the MKX controller, which provides better performance and power management compared to the MJX controller found in the 860 EVO. Additionally, the 870 EVO uses higher-quality 3-bit MLC V-NAND flash memory, while the 860 EVO uses 3-bit MLC NAND flash memory. This upgrade in memory technology allows for improved endurance and reliability.

Endurance and Reliability

Speaking of endurance, the Samsung 870 EVO SATA III SSD has a higher TBW (Terabytes Written) rating than its predecessor, with up to 300 TBW for the 1TB model. In comparison, the 860 EVO has a TBW rating of up to 200 TBW for the 1TB model. This means that the 870 EVO can handle more write cycles before its performance starts to degrade.

Power Consumption

In terms of power consumption, both drives are relatively efficient, with the Samsung 870 EVO SATA III SSD consuming an average of 2.2 watts during read operations and 3.3 watts during write operations. The 860 EVO consumes an average of 2.5 watts during read operations and 4.0 watts during write operations.

Capacity Options

Both drives are available in a range of capacities, from 250GB to 4TB for the 870 EVO and 250GB to 4TB for the 860 EVO. However, it's worth noting that the higher-capacity models of the 870 EVO may offer better performance due to the improved controller and memory.

Price

In terms of pricing, the Samsung 870 EVO SATA III SSD tends to be slightly more expensive than its predecessor, with prices starting at around $50 for the 250GB model. The 860 EVO, on the other hand, can be found for as low as $40 for the 250GB model.

Conclusion

In conclusion, while both Samsung SSDs offer excellent performance and reliability, the 870 EVO SATA III SSD has a slight edge over its predecessor due to its improved controller, memory, and endurance. If you're in the market for a high-performance SATA III SSD, the 870 EVO is definitely worth considering. However, if budget is a concern, the 860 EVO remains a great option that still offers excellent performance at a lower price point.

Ultimately, when it comes to choosing between these two Samsung SSDs, it's essential to consider your specific needs and priorities. If you require the absolute best performance and endurance, the 870 EVO may be the better choice. But if you're looking for a more affordable option that still delivers great results, the 860 EVO is an excellent value.
