Comparing SSD and NVMe Technologies

Table of Contents

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

  1. MLC V-NAND is the best option.
  2. TLC is equivalent to V-NAND, and viceversa.
  3. QLC is cheap but a little less reliable.
  4. 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 $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)

Conclusions

  • Cheap system? Get any of these.
  • Secondary drive? Get any QLC or better.
  • OS Drive? Get any TLC or better.
  • Extra cash? Premium for reliability? Get any Samsung from the list.
