SSD / NVMe Comparison
This page was originally published on July 28, 2023. Its main goal was to aid in selecting SSD, and NVMe drives during a Micro Center sale.
Storage Technologies
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.
Let's break it down:
- MLC V-NAND (Best)
- V-NAND (TLC Equiv.)
- TLC (V-NAND Equiv.)
- QLC (Cheap, less reliable)
- 3D NAND (Basic)
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 $1. Selected $0.10 as the baseline after averaging some calculations.
- 1 point for every $0.01 / GB below $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)
