Description
Four terabytes on a single-sided M.2 is what QLC is for. Note that the 4 TB variant runs slightly below the 2 TB one on sequential figures — 4800/4100 against 5000/4200 — which is the opposite of the usual pattern and worth stating rather than rounding up to the line's headline number.
Key specifications
- Sequential 4800 MB/s read, 4100 MB/s write (within SLC cache)
- 800 TBW endurance, 5-year limited warranty
- Micron 3D QLC, DRAM-less (HMB)
- PCIe 4.0 x4, backwards compatible with PCIe 3.0
Where it fits
Single-drive media archives, backup targets and game libraries in a chassis with no room for a second drive. Sustained write beyond the SLC cache drops sharply — do not quote it as a capture or scratch volume.
Trade notes
Retail-boxed. The cost-per-terabyte leader in the range; check the current sheet before quoting, as QLC pricing moves faster than the TLC lines.
