About this tag
The tlc and qlc tag on WindowsForum.com covers discussion of NAND flash types used in consumer and enterprise SSDs, particularly how triple-level cell and quad-level cell designs affect real-world performance. A recurring theme is the gap between advertised peak speeds and sustained write behavior, including pseudo-SLC caching, performance drops during large copies, and how drives slow as they fill. These threads help Windows users, PC builders, and administrators interpret SSD specifications more realistically when choosing storage for desktops, laptops, or servers, rather than relying on benchmark numbers alone.

    SSD Buying: Check Sustained Writes, Not Peak Speed

    The sudden drop from several gigabytes per second to a few hundred megabytes per second during a large SSD copy is often real, but “every SSD has a hidden fast lane” overstates what is happening. The XDA Developers explainer correctly points to pseudo-SLC caching as a common reason consumer...
