In the world of PC hardware, people want faster, more dependable, and affordable storage. One big change in this area is TLC (Triple-Level Cell) NAND flash memory. It’s a technology that’s essential for the storage in most of our devices. This article will explain what TLC is, how it’s different from other types like SLC and MLC, and where you can see TLC in your PC setup.

Key Takeaways
- TLC (Triple-Level Cell) is a type of NAND flash memory that stores up to three data bits per cell.
- Compared to SLC and MLC, it offers better affordability at the expense of speed and durability.
- TLC NAND flash memory is commonly present in consumer-grade SSDs and high-capacity USB drives.
What Is TLC?
TLC or Triple-Level Cell is a type of NAND flash memory used in various storage devices like Solid-State Drives (SSDs). As apparent by name, it can store up to three data bits in one cell[1]. This, in turn, provides a higher storage capacity compared to SLC and MLC, which can only store one and two bits per cell, respectively. The unique feature of TLC lies in its better affordability while still giving good speed and reasonable durability[2].
SLC vs MLC vs TLC
SLC NAND flash memory is known for its speed and durability, making it ideal for high-performance applications where cost is not a primary concern[3]. MLC NAND offers a balance between performance and cost and is commonly available in consumer-grade SSDs and data centers. Finally, TLC NAND provides a higher storage capacity at a lower cost, making it a popular choice for consumer-grade SSDs and portable devices[4]. To better understand the differences between these three, I have created a comparative table:
| Attribute | SLC | MLC | TLC |
|---|---|---|---|
| Bits per Cell | 1 | 2 | 3 |
| Performance | Fast | Moderate | Moderate |
| Endurance | High | Moderate | Moderate |
| Capacity | Low | Moderate | High |
| Cost per GB | High | Moderate | Low |
| Common Use Cases | Enterprise storage, high-performance computing | Consumer-grade SSDs, data centers | Consumer-grade SSDs, portable devices |
Where Is TLC Used?
You can find TLC NAND flash memory in various PC hardware components, mainly in consumer-grade SSDs. These drives are often the go-to choice for those looking to enhance their PC’s performance without breaking the bank. TLC-based SSDs offer a compelling mix of affordability and decent performance, making them suitable for various applications, from gaming to general productivity tasks[1].
