摘要：The deletion of data from storage is an important component on data security. The deletion of entire disc or special files is well-known on hard drives, but this is quite different on SSDs, because they have a different architecture inside, and the main problem is if they serve the same methods like hard drives for data deletion or erasing. The built-in operations are used to do this on SSDs. The purpose of this review is to analyses some methods which are proposed to erase data form SSDs and their results too, to see which of them offers the best choice. In general we will see that the techniques of erasing data from entire disc from hard drives can be used also on SSDs, but there’s a problem with bugs. On the other hand, we cannot use the same techniques of erasing a file from hard drives and SSDs. To make this possible, there are required changes in FTL layer, which is responsible for mapping between logic addresses and physical addresses.
