<p><span>固态硬盘经过几年的高速发展，以其高速存取、性能稳定、坚固抗摔等优势成为广大消费者的选择，尤其是在高性能<span lang="EN-US">PC</span>中，<span lang="EN-US">M.2</span>接口的<span lang="EN-US">SSD</span>被广泛应用。虽然去年<span lang="EN-US">AMD</span>的<span lang="EN-US">X570</span>平台已经开始支持<span lang="EN-US">PCIe 4.0</span>，不过在目前的固态硬盘市场，<span lang="EN-US">PCIe 3.0</span>仍然是主流产品，采用<span lang="EN-US">M.2</span>接口的<span lang="EN-US">PCIe 3.0x4</span>通道的<span lang="EN-US">SSD</span>基本都是各家厂商主推的旗舰级产品。</span></p>

<p><span>作为存储业界巨头，美光（<span lang="EN-US">Micron</span>）是为数不多的拥有闪存、控制器、固件等在内的全产业链能力的企业之一，旗下也有多个存储品牌。今年<span lang="EN-US">4</span>月，美光旗下<span lang="EN-US">Crucial</span>（英睿达）品牌推出了一款采用<span lang="EN-US">M.2</span>接口的高性能<span lang="EN-US">NVMe SSD</span>：<span lang="EN-US">Crucial P5 3D NAND NVMe M.2 SSD</span>，采用先进<span lang="EN-US">NVMe</span>技术，最高提供<span lang="EN-US">2TB</span>容量。下面为大家带来<span lang="EN-US">Crucial P5 NVMe M.2 SSD</span>（<span lang="EN-US">500GB</span>）的评测内容。</span></p>
