■ 平均访问时间： DVD－ROM：120毫秒，CD－ROM：90毫秒
通过增强DVD－A05S的整体性能，使得它能迅速地访问特定的数据区域。当读取DVD－ROM时，随机访问时间仅为120毫秒。同时，扫描低密度的CD－ROM时，访问速度为90毫秒。

■ 插入式光碟的机械装置（同时提供托盘结构的型号）
先锋采用插入式光碟机械装置，一方面避免光碟的损坏，也便于用户水平或垂直安装驱动器。这种机制，能方便地读取光碟两面，避免接触数据面。另外，弹出光碟的时候，用户可以抓取裸露出来的光碟中心圆孔，从而避免手指碰到数据部分。

■ 能够读取单层和双层的DVD－ROM／DVD视盘碟，DVD－R，CD－ROM光碟，CD唱片，CD－R／RW，VCD，PHOTO CD，HYBRID CD，CD－EXTRA（加强型CD）
