Questions about this item

How does the MLC NAND in the 860 PRO 256GB handle write endurance during sustained workloads?

The MLC architecture provides higher program/erase cycle tolerance than TLC alternatives, allowing the 256GB drive to sustain heavy write workloads without early wear concerns.

What thermal behaviour should I expect from the 2.5-inch 860 PRO when running continuously in a laptop or desktop?

With no moving parts and low-power SATA operation, the drive stays cool under sustained loads; the metal casing helps dissipate heat so temperatures remain stable during all-day use.
