The new SSD Crucial M600 is able to change the mode of its chips between MLC and SLC

Crucial has introduced its new generation of SSD for the domestic market. The SSD Crucial M600 is one of the greatest innovations with its memory chips manufactured at 16 nanometers with a capacity of 16 GB (128 GB) type MLC, but are capable of changing dynamically to SLC mode when the cells are empty. In such a manner that the capacity of each cell is reduced by half and allows much faster script writing with less consumption. Once the cells are filled it changes back to MLC mode to increase its capacity.

While the SLC cells are filling, the SSD transfers existing data to cells in MLC mode. This is why we will maintain SLC cells (much faster). Naturally, the more space we occupy in SSD, the more the available SLC cells will decrease and we will lose this improvement. However, in order for this to happen we would have to fill almost all the disk. Top speed is achieved when the SSD is below 50% capacity.

SLC memory types allow the achievement of superior velocities to MLC and TLC memory speeds, with higher durability, but at the cost of a reduction in capacity (1 bit per cell).

To clarify the whole issue of the types of memories that are usually integrated in SSD, you can take a look at this article published in the forum: Types of memories SSDs: SLC, MLC and TLC.

They will come in 4 sizes, 128 GB, 256 GB, 512 GB and up to 1TB (SATA) capacity, and in formats SATA, mSATA and M.2 reaching sequential speeds of 560 MB/s for reading and 510 MB/s for writing.

Thanks to the new SLC / MLC technology with "Dynamically accelerated writing" it is able to maintain high write speeds with even larger models that come in lower capacities and that are traditionally slower. In fact, all models maintain the 510 MB/s write speed except 128 GB, which retains a more than decent 400 MB/s.

At the moment we have no information regarding its price.
