与去年的970 Evo相比，三星970 Evo Plus是970 Pro的更好，更便宜的替代品。与其前代产品相比，新的SSD几乎在每个方面都脱颖而出。虽然读取速度的提高不那么明显，但写入速度有了明显提高。
“三星在其已经领跑市场的970 Evo上进行了改进。经过在其前身上的改进，970 Evo Plus成为消费级固态硬盘的新领头羊。”
除了1TB版本之外，970 Evo Plus目前的售价比970 Evo高出约160元（参考）。970 Evo Plus在我们看来是值得升级的，但970 Evo已经是一流的固态硬盘，因此它仍然是大多数人的选择。不过这两块固态硬盘的价格将如何随着闪存成本的降低而波动？让我们拭目以待。
