Should You Upgrade Your Mac's RAM or SSD?

Introduction

  • Speaker: Chris, a software developer
  • Context: Deciding on Mac upgrades (RAM, SSD)

Key Concepts

RAM (Random Access Memory)

  • Short-term memory of the computer
  • Fast and powerful but forgetful
  • Analogy: Whiteboard - Info stays until erased

SSD (Solid State Drive)

  • Long-term memory of the computer
  • Can get cluttered over time
  • Writing/rewriting files damages SSD over time
  • Analogy: Chalkboard - Over time, it gets smudged and messy

Swap Memory Usage

  • Makes use of SSD when RAM is overloaded
  • Analogy: Using chalkboard when whiteboard is full
  • Helps during high workloads but can lead to SSD wear over long-term use

Recommendations

  1. For Most Users (90-95%)

    • Base model MacBook Air with 8GB RAM and 256GB SSD is sufficient
    • Normal activities won't heavily use swap memory
    • Cost-effective choice
  2. For Power Users (5-10%)

    • Engage in heavy multitasking, rendering, or 4K editing
    • Upgrade to 16GB RAM
    • External SSDs (e.g., Samsung T5/T7 Shield) recommended over expensive internal SSD upgrades

Personal Experience

  • Base Model Usage: Worked fine for first 1.5 years of full stack development
  • Issue: Swap memory usage became noticeable only during 4K editing/rendering
  • Upgrade Path: Opted for M1 MacBook Pro with 16GB RAM, 512GB storage + external SSDs

Final Tips

  • Save money: Most don't need high upgrades
  • External SSDs: Affordable, flexible storage options
  • Know your workload: Upgrade based on actual needs
