    这是一个创建于 1994 天前的主题,其中的信息可能已经有所发展或是发生改变。
    Since the performance requirements to retrieve and display a BLOB value might be very different
    from other data types, you could put the BLOB-specific table on a different storage device or even a
    separate database instance. For example, to retrieve a BLOB might require a large sequential disk
    read that is better suited to a traditional hard drive than to an SSD device.

    疑惑主要有两个
    1. you could put the BLOB-specific table on a different storage device or even a separate database instance
    如何将表放到另一个存储设备 /另一个数据库实例中?
    2. to retrieve a BLOB might require a large sequential disk read that is better suited to a traditional hard drive than to an SSD device.
    对于需要大量序列磁盘读取的情景, 传统磁盘优于 SSD? 为什么?

    可以的话请知道的 dalao 解答一下.
