[图表]英特尔第三代X25-M固态硬盘消息泄露
发布日期:2010-10-07 07:05:31  稿源:
英特尔发布第二代X25-M的固态磁盘已经有14个月了,按照发布周期来看,今年年底明年年初将会有更新版本的产品出来,不过本次升级应该只是加强版而非全新产品。
据AnandTech报道,英特尔新版固态硬盘已经出样,但还没有开始批量生产。
这种第三代驱动器提升了现有的读写速度到250MB/s和170MB/s,在读取4KB随机文件的时候可以带来更高性能,分别达到50K IOPS和40K IOPS,并且开始全面扩张容量。

由于技术的成熟和存储密度不断提高,SSD已经初步开始具有相当的竞争力,下一步我们能预期的就是价格下降。
