SLC versus MLC (0)

SLC, MLC, Write Speed

Solid state drives write the data into memory cells. This cells are made of floating-gate transistors.

Single Level Cell (SLC)
SLC flash memories store only one bit of data in a single cell. Each cell stores one bit. So SLC memories are capable of faster write. SLC also has the advantage of higher cell endurance and lower power consumption. Although SLC technology has so many advantages, it costs more than MLC. SLC technology is chosed for servers and heavy applications by companies.
