He added that 4-bit terabyte-SSD products will now rapidly spread throughout the entire market. Stack enough of those together, and you can get a lot of storage in the standard 2.5-inch SSD form factor at lower costs.
The new 4-bit technology is based on Samsung's 1Tb V-NAND. At the time, it ensured consumers that the new memory solutions would allow for the creation of solid state drives (SSDs) with significantly increased capacity.
Storing more bits per cell in QLC drives inevitably means lower performance and endurance when compared to TLC, but Samsung claims it has managed to maintain the performance level of existing TLC drives.
A major impediment to making 4-bit NAND a reality has been the substantial performance hit due to lower charge levels.
The company revealed today that it has begun mass production on a new 4-bit quad-level-cell SSD that boasts 4TB of storage.
4-bit QLC has been a tricky thing to figure out, because while the potential for higher capacity is there, write speeds tend to suffer in the jump from three bits to four.
Consumers will have the option of picking up the new Samsung SSDs in 1, 2, and 4TB capacities.
The company also expects to provide M.2 NVMe SSDs for enterprises and start mass production of 4-bit 5th-generation V-NAND.
Interestingly, Samsung said it will use the same chip to "efficiently" produce a 128GB memory card for smartphones. At least there's plenty of competition in the QLC space, so hopefully we'll be pleasantly surprised by the price.
