Comparing SSD and NVMe Technologies

The main goal of this post was to aid in selecting SSD, and NVMe drives during a Micro Center sale. But I'll try to give an overview of what to look for next time you find yourself in the same position.
Storage Technologies
- MLC V-NAND is the best option.
- TLC is equivalent to V-NAND, and viceversa.
- QLC is cheap but a little less reliable.
- 3D NAND is your basic entry point to SSDs.
3D NAND
- The most basic of modern SSD technologies. Great for throwing on cheap systems, home servers, anything non-critical really.
- It is not recommended to host your Operating System on 3D NAND, or QLC.
Quad Level Cell (QLC)
- QLC (Quad Level Cell) is cheaper to manufacture than TLC (Triple Level Cell).
- QLC is much slower and less durable to constant writing than TLC.
- It is not recommended to host your Operating System on 3D NAND, or QLC.
Triple Level Cell (TLC)
- TLC is more reliable when compared to QLC.
- MLC is a Triple Level Cell based Samsung technology.
Multi Level Cell (MLC)
- MLC is a Triple Level Cell based Samsung technology.
How Are SSDs Scored
Storage
- 1 point per GB
- Less accurate the bigger the SSD
- 3 TB and higher drives scale exp/log instead of linearly.
Price
Based on price per 0.10 as the baseline after averaging some calculations.
- 1 point for every 0.10
Technology Coefficient
- 3D NAND Coefficient = 0.5 (Big Penalty)
- QLC Coefficient = 0.75 (Small Penalty)
- TLC Coefficient = 1.0 (No Change)
- MLC V-NAND coefficient = 1.25 (Small Advantage)
