Someone recently asked The SSD Guy if there is a way to determine whether an SSD is SLC, MLC, eMLC or TLC.
I found it a little odd to be asked this, since most vendors tell what kind of flash they use in an SSD’s specifications, especially if it’s SLC.
Not finding it there then the next thing I would look at is the price. Raw SLC NAND flash now sells for about 6-10 times as much as its MLC counterpart, so an SSD with a price of around $1/GB is likely to be MLC and one that sells for around $10/GB is probably SLC.
TLC SSDs are really rare. There is the Continue reading “What’s In My SSD? SLC, MLC, or TLC?”

It’s tough to design an SSD controller, and even tougher to make one that can simply compete against the great ones that already ship in volume. To make a truly better controller would seem to require an astonishing effort. It appears that a company with a very odd name: 
DensBits, a flash memory controller company, has just introduced its new DB3610 “Memory Modem” eMMC controller for 3-bit or TLC flash. The controller is the first to use DensBits’ new technology which the company claims can coax better reliability out of 3-bit flash than most controllers can out of 2-bit MLC, to provide important cost savings to OEMs.
