QVO, MLC, TLC, MLC in SSD terms can be confusing, even if they are just standards!
The 860 QVO series at Samsung, which uses what Samsung calls 4-bit MLC, what we commonly refer to as QLC, or Quad-Level Cell Flash. The technology stores a fourth data bit per cell above the DC memory, but doubles the number to 16. The controller must differentiate between the 16 levels in order to be able to read and write the existing data.
SS (Solid State Drives) are different types of NAND flash memory cells used in SSDs (Solid State Drives). Here are the common abbreviations and their meanings:
1. SLC (Single Level Cell)
2. MLC (Multi-Level Cell)
3. TLC (Triple Level Cell)
4. QLC (Quad Level Cell)SLC is the oldest and most robust NAND flash technology. With SLC, only one bit is stored per memory cell. This results in high speed and long life, but also makes SLC SSDs more expensive and offers less storage capacity per chip.
MLC stores more than one bit (usually two bits) in each memory cell. This enables higher storage capacities per chip and reduces production costs compared to SLC. However, MLC SSDs are slower and have a shorter lifespan.
TLC stores even more bits per cell (typically three bits). This leads to a further increase in memory capacity per chip and lower production costs. However, TLC SSDs are slower and have an even shorter lifespan than MLC SSDs.
QLC is the latest technology and stores four bits per cell. This offers the highest storage capacity per chip, but makes QLC SSDs the slowest and more prone to wear compared to SLC, MLC and TLC.
The choice between these NAND flash technologies depends on the requirements of the respective application area. For example, SLC SSDs are used in enterprise applications where speed and reliability are critical. MLC and TLC SSDs are widely used in consumer products, with MLC SSDs found in higher-end products. QLC SSDs are often used in inexpensive, large storage drives where speed is less critical.
