Detailed explanation-1: -All USB flash drives, SD cards and SSDs have a NAND controller that manages the NAND flash and performs functions such as wear leveling and error correction.
Detailed explanation-2: -Most commonly, there are two kinds of flash storage used today, NOR and NAND. NOR is the older of the two and is physically larger than NAND memory. NAND is more expensive but has a reduced size and faster write speeds, making it the ideal choice for most SSDs.
Detailed explanation-3: -Single-level cell (SLC) NAND stores only 1 bit of information per cell. The cell stores either a 0 or 1 and, as a result, the data can be written and retrieved faster. SLC provides the best performance and the highest endurance with 100, 000 P/E cycles so it will last longer than the other types of NAND.
Detailed explanation-4: -When navigating these higher speed and lower latency protocols, you might be wondering, what the difference is between NVM Express® (NVMe®) technology and NAND? NVMe technology is not a competitor to NAND. In fact, NVMe technology provides an interface and protocol that fully unleashes the power of NAND.
