Per storage cell, only one bit is written on an SLC SSD. We are already familiar with the term from the storage types as explained above. Meanwhile, some SSDs have a so-called SLC mode. By this, all storage cells are treated with care as good as possible.

SSDs of the new generations apportion data on the whole storage. With “Wear Leveling” SSDs have made a big step towards more robustness. This means, by only reading data, an SSD will not wear out, which brings us to the conclusion that it depends on the write and delete processes. However, in comparison to conventional HDDs, the mechanics of SSD don’t degrade when only reading data. In the first moment, that necessarily doesn’t sound much. Storage cells of type MLC last about 3,000 write cycles. That means, at first the life span of storage types possibly can be linked to the write cycles. SLC flash storages haven’t become accepted yet because of their horrendous prices.įor the storage types and their life span applies the following: The more data per cell is saved, the higher the wear level is. The storage type MLC saves two bits per storage cell, the TLC type three bits per cell and the SLC type only one bit. These names already adumbrate the difference. Three SSD storages are available: Single Level Cell (SLC), Multi Level Cell (MLC) and Triple Level Cell (TLC). If you deal with the expected life span of an SSD, you first have to have a look at the variable storage types of SSD drives. Someone who aks this question in relevant internet forums, mostly gets a variety of most diverse opinions. Some years have passed and new chips and procedures have immensely improved the technology. However, the development of SSD technology hasn’t stagnated since then. In fact, the starting times of SSD drives weren’t easy: The first SSD storages suffered from firmware problems and decreases of power.
