Samsung 860 EVO 1 TB SSD reviewed – Tech Report



Samsung 850 EVO has long been considered the top of the SATA SSD market. It served our recommendation when it launched back in 2014 and has been the 800 pound gorilla of the client's SSDs ever since. Samsung was the first to produce a non-plan TLC NAND drive, and 850 EVO's success has affected the shape of the entire SSD market since. Pick up a random SSD and peer inside, and the odds are high that you will find 3D TLC NAND of any kind that gazes back on you.

Non-planar NAND technologies – either "3D", "BiCS" or "V-NAND" garden have become the de facto standard for regular solid state storage. And it's not likely to change soon, unless more exotic technologies accumulate from the steam. The only trustworthy threat comes from quad-level-cell NAND. Currently, QLC products seem to target enterprise-y "write once, read many" workloads, where technology inevitably poorer write performance and stamina can go unnoticed. But maybe it's just a matter of time before some tough manufacturers decide that cost savings outweigh the potential consumer's setback and force it into the client's room. I expect a lot of mocking and sparking of teeth in the comments when it happens, so start composing diatribes today.

Anyway, the game name is still non-planart TLC for now, and as we have discussed in our 860 Pro Review, Samsung has used the past few years to make generational improvements to its V-NAND .
