Manufacturer description

The Samsung 860 PRO 256GB is a 2.5-inch SATA III internal solid state drive built on Samsung V-NAND technology, aimed at mainstream PCs, laptops, workstations, and NAS builds. It reaches sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s, with random performance rated at up to 100,000 IOPS read and 90,000 IOPS write at 4KB QD32. At low queue depths, where everyday desktop work actually lives, it is rated for up to 11,000 IOPS random read and 43,000 IOPS random write. Samsung pairs the MLC V-NAND with an algorithm-based controller tuned to hold speeds consistent…

SpecPicks Verdict

SpecPicks scored Samsung 860 PRO SSD 256GB using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Samsung's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
