即将被西部数据收购的日立环球存储技术公司（HGST）今天发布了搭载MLC闪存颗粒的企业级固态硬盘新品Ultrastar SSD400M，将于下月量产出货。

相比之前的Ultrastar系列企业级固态硬盘，SSD400M从SLC闪存颗粒更换为Intel出品的25nm制程MLC颗粒。为提供企业级数据安全性，SSD400M除了ECC校验功能外，还专门提供了“企业A安全子系统”（Enterprise A Security Subsystem）加密功能。日立标称的平均无故障工作时间为200万小时，保修期达到5年。

Ultrastar SSD400M采用SAS 6Gbps接口，容量200GB或400GB，最大连续读取速度495MB/s，写入385MB/s，随机读取56000 IOPS，随机写入24000 IOPS。硬盘尺寸达到70.1x100.6x15mm，重186g，运转功耗5.5W，待机1.7W。该硬盘即日起开始提供样品，9月量产出货。
