Micron（美光）今天发布了2210和2230系列M.2 SSD，其中2210系列采用低成本的QLC颗粒，性能中规中矩，但容量很大，而2300系列采用自家最新3D TLC颗粒，性能和耐用性较优秀，相对而言还不错，两款都属于入门级M.2 SSD，主打容量和性价比。

美光2210系列采用M.2 2280规格，主控细节未透露，搭载自家QLC NAND颗粒，有512GB/1TB和2TB三种容量，走PCIe x4通道，兼容NVMe 1.3协议，有SLC缓存写入加速、AES 256bit加密和TCG Opan 2.0以及断电保护等。性能上，最高连续读写分别为2200MB/s和1800MB/s，4K随机读写分别为265K IOPS和320K IOPS。

美光2300系列也是M.2 2280规格，采用自家96层3D TLC颗粒，有256GB、512GB、1TB和2TB四种容量可选，主控细节未透露，同样也是PCIe x4通道、兼容NVMe1.3协议，技术支持也都完全相同。性能上要比2210优秀的多，最高连续读写分别为3300MB/s和2700MB/s，4K随机读写分别为430K IOPS和500K IOPS。

由于2210系列是QLC颗粒，所以耐用性上要差一些，512GB、1TB和2TB分别为180TBW、360TBW和720TBW；而采用TLC的2300系列256GB/512GB/1TB/2TB分别为150TBW、300TBW、600TBW、1200TBW，两款都提供200万无故障运行寿命，未提及质保。
