What’s the difference between the 860 EVO and 870 EVO?

Samsung recently released the 870 EVO SATA 2.5″ Solid State Drive. So, how does the new model compare to the older 860 EVO?

You can find out in this comparison guide between these two internal SSDs.

Quick Summary

When compared to the Samsung 860 EVO SATA 2.5″ Solid State Drive, the new Samsung 870 EVO SATA 2.5″ SSD has a slightly faster maximum sequential reading speed and maximum sequential writing speed.

The 870 EVO also consume more power than the older model.

Otherwise, the two internal storage drives are identical when it comes to endurance, reliability, warranty coverage and other features.
