description A solid state disk storing log frames and log entries is provided. The provided solid state disk comprises a nonvolatile storage medium comprising a plurality of physical pages; wherein the physical page comprises one or more FTL frames and/or one or more log frames; wherein each FTL frame comprises a plurality of FTL table entries and metadata recording a storage position of a previous FTL frame belonging to the same FTL block as the FTL frame, and each log frame comprises a plurality of operation log entries and recording a storage position of a previous log frame belonging to the same FTL block as the log frame; each operation log entry comprises a logical address and a physical address corresponding to the logical address, and the FTL block is part of an FTL table. 提供了存储日志帧以及日志条目的固态硬盘。所提供的固态硬盘包括：包括多个物理页的非易失存储介质；其中物理页包括一个或多个FTL帧和/或一个或多个日志帧；其中每个FTL帧包括多个FTL表条目与记录了与该FTL帧属于同一FTL块的前一个FTL帧的存储位置的元数据，每个日志帧包括多个操作日志条目与记录了与该日志帧属于同一FTL块的前一个日志帧的存储位置，每个操作日志条目包括一个逻辑地址以及与之相对应的物理地址，以及FTL块是FTL表的部分。
