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。
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。
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。
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。
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。
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。
Static wear-leveling algorithms address this by periodically moving stale data to new blocks.
静态平均读写算法解决了这一问题，因为它可以定期将数据移动到新块。
Although JFFS was very useful in its time, its wear-leveling algorithm tended to shorten the life of NOR flash devices.
尽管JFFS在早期非常有用，但是它的平均读写算法容易缩短NOR flash设备的寿命。
To maximize the life of the flash, wear-leveling algorithms are provided.
