data block address

On a write, the DIF is generated by the host bus adapter (HBA), based on the block data and logical block address.

在写数据时，主机总线适配器(HBA)根据块数据和逻辑块地址生成dif。

The header contains general block information, such as the block address and the type of segment (for example, data or index).

这部分的数据块包含了有关实际的行的信息（包括行数据区域每个行片段的地址）。

Next, the controller repeats the above operation until the reserved block corresponding to the access block address is the normal block, and access to data with the access block address.

接下来，控制器重复上述操作直至存取区块地址所对应的备用区块为正常区块后，根据存取区块地址存取数据。
