the ssd is brand new, yet the health report from crystal disk indicated 100% and didn't show any firmware update needed. i thought so—i confirmed there was no firmware available.
This setup matches what you outlined—it functions as a mix of storage and cache. It manages both data retention and quick access without needing the whole SSD to be filled. The fullness happens only where needed for performance.
The NAND is based on QLC technology, yet it takes time to write data, so a part of it is stored in SLC for faster access. When you use SLC, it consumes 3-4 times the capacity from the main storage, reducing available space. To maintain balance, allocation stays within what the maker thinks is practical. For example, with 100GB free and 100GB QLC, only 25GB can be cached. After using 25GB for cache, you'd retain 75GB free, but the drive can't store more until it updates the cache to QLC, which slows things down.
It’s done because converting from SLC to QLC takes more time, and 3D NAND refers to a storage technology where data is packed in three dimensions for higher density.
Directly writing to QLC would always be slow. Cache provides speed for several dozen gigabytes at once. Writing more than that in one session is rare, so you usually won’t notice the QLC’s sluggishness. It’s typically just multiple dies packed together. If it weren’t for quick cache clearing, it would likely be noticeable. The term “time to flush” isn’t commonly mentioned in reviews, probably because it would be hard to measure accurately.
