MLC and TLC and QLC NAND

SCH.cxUse of MLC, TLC and QLC NAND in the CHIA Plotting Disk. MLC> TLC> QLC’s performance (program and erase time) and endurance (the amount of data that can be written to the device before it runs out). Due to excellent SSD performance and sufficient durability (usually up to 3 drives are written per day and 10,000 NAND program/erase cycles are performed), data center SSDs have been specifically transferred to TLC. This raises the argument that MLC is no longer needed.

Consumers want lower-cost solid-state drives, so QLC entered the market. Due to longer program time and lower battery life, its performance is currently much worse than TLC, but do not expect to improve industry performance like TLC. Even for QLC devices, durability is not actually an issue for consumers. This is simply due to the nature of how much data standard consumers write on their devices every day.

Performance can also be masked by peculiar algorithms, caching and dynamic SLC mode. Generally, these methods are suitable for mainstream and entry-level devices, but not for data center, enterprise, and demanding creator/workstation use cases. If you are buying a second-hand data center SSD (such as P3700) that is 5-6 years old, you may still find MLC drives.

QLC is very suitable for capacity-optimized drives and is widely used for cloud object storage, AI, etc… However, they are not suitable for drawing due to the trade-off between write performance and durability (which are both necessary for drawing). If you are buying a second-hand data center SSD (such as P3700) that is 5-6 years old, you may still find MLC drives. QLC is very suitable for capacity-optimized drives and is widely used for cloud object storage, AI, etc… However, they are not suitable for drawing due to the trade-off between write performance and durability (which are both necessary for drawing).
