1·The three most important are garbage collection, managing bad blocks, and wear leveling.

三个最重大的挑战分别是垃圾收集、管理坏块和平均读写。

2·Dynamic wear leveling addresses the problem of a limited number of Erase cycles for a given block.

动态平均读写解决了块的Erase周期的次数限制。

3·Technology of wear leveling and page mapped prolong the flash storage life-span, and the design of efficiency memory management improves the rate of data retrieval.

按字节静态分配存储空间、合理有效地回收与重用碎片空间，提高了存储空间的利用率；

4·By illustrating the implementation of the module interfaces, node structure and the algorithms of wear leveling and garbage collection, the paper shows that compared with other products of.

通过描述该文件系统各模块接口、节点结构以及负载平衡和垃圾收集算法，显示出该系统相比其他同类产品具有存取速度快、芯片使用寿命长和稳定性高等优点。

5·To make matters worse, the SSD must internally shift data to minimize the introduction of errors in a process called garbage collection or wear-leveling.

更糟的是，SSD必须内部切换数据以便尽可能减低在称为垃圾收集或耗损均衡的进程中引入错误的可能。

6·When the SSD receives this new command, it can add the blocks defined to its free list and no longer worry about moving them around as part of wear-leveling.

当 SSD 收到这个新命令后，它就可以将所定义的那些块添加到其释放列表，不会再担心这些块再成为损耗的一部分。

7·This ability allows the SSD to remove these blocks from wear-leveling processes and helps to increase the endurance of the drive.

此功能允许SSD从耗损均衡进程删除这些块，并有助于增加驱动器的耐力。

8·Rather than randomly using blocks as they are available, dynamic wear-leveling algorithms attempt to evenly distribute the use of blocks so that each gets uniform use.

动态平均读写算法并不是随机使用可用的块，而是平均使用块，因此，每个块都获得了相同的使用机会。

9·When a block is freed in the SSD, it is no longer a target of wear-leveling and therefore can minimize the overall wear on the device.

当某个块从此ssd释放后，它就不再是被耗损的对象了，进而能将此设备的总体耗损降至最低。

10·Static wear-leveling algorithms address an even more interesting problem.

静态平均读写算法解决了一个更有趣的问题。
