M2 Mac - 8GB vs 16GB RAM - Avoid This Costly Mistake!

Introduction

Introduction

Are you in the market for a new Mac but unsure whether to spend the extra cash on built-in upgrades like a larger SSD or more RAM? If you're new to the world of Mac, this article will give you insights that could save you money and help you make an informed decision.

As a software developer who once faced this same dilemma, I found many videos on the topic lacking crucial information regarding swap memory usage. Understanding how swap memory functions is vital when deciding on hardware configurations for your Mac.

RAM vs SSD

What is RAM?

RAM stands for Random Access Memory. It acts as the short-term memory of your computer—it's extremely fast but volatile. This means it holds data temporarily: when you turn off your device, everything in RAM is lost. Analogous to a whiteboard, RAM can display information instantly, but once it is wiped clean, that information is gone forever.

What is an SSD?

An SSD, or Solid State Drive, serves as long-term storage for your computer. While it excels at remembering and storing files, it can become cluttered over time. You can think of it as writing on a chalkboard; eventually, you'll need to erase old information to make space for new content. However, continuously writing and erasing data can lead to performance degradation and wear on the SSD.

Understanding Swap Memory Usage

If we return to our classroom analogy, imagine the scenario where you run out of space on your whiteboard while trying to solve a complex equation. To continue, you'd have to start using the chalkboard, which is a slower process. Swap memory operates similarly: when your Mac's RAM is overloaded, the system utilizes the internal SSD to temporarily store data that would normally reside in RAM.

For most users, this swap memory usage won't be a significant issue, as regular tasks don't typically require heavy memory utilization. However, if you frequently engage in power-hungry activities—like video editing or extensive multitasking—you may experience noticeable slowdowns and potential SSD wear.

Recommendations

General Users

For about 90-95% of users who engage in light to moderate workloads, I recommend opting for the base model MacBook Air with 8GB of RAM and 256GB of SSD storage. This configuration saves you money while still providing an excellent user experience.

Power Users

If you belong to the 5-10% of users who perform heavy workloads, such as video editing, 3D rendering, or multitasking with numerous applications at once, investing in 16GB of RAM is worthwhile. However, I generally advise against the high costs of upgrading built-in SSD storage. Instead, consider purchasing an external SSD like the Samsung T5 or T7 Shield, both of which offer 1TB of storage for under $ 100.

My Experience

In my own journey, I used the base model MacBook Air for my first year and a half as a full-stack developer. I managed to run multiple browsers, code editors, and servers without issues until I began adding 4K video editing to my workflow. At that point, the increase in swap memory usage led to decreased performance, prompting me to upgrade to an M1 MacBook Pro with 16GB of RAM and 512GB of storage. I also invested in a couple of external SSDs for additional storage.

FAQ

1. Should I choose 8GB or 16GB of RAM for my Mac?

If you're a light to moderate user, 8GB of RAM is typically sufficient. For power users frequently engaging in heavy tasks, consider upgrading to 16GB.

2. Is upgrading the SSD worth it?

Upgrading the built-in SSD is often overpriced. It’s generally better to invest in an external SSD for additional storage.

3. What is swap memory usage?

Swap memory is a process your Mac uses to temporarily store data on the SSD when RAM is full, allowing your computer to continue operating.

4. Can I experience slowdowns with 8GB of RAM?

While most everyday tasks won't cause issues, users engaged in heavy multitasking or resource-intensive applications may experience slowdowns or performance degradation due to swap memory usage.

5. What external SSDs do you recommend?

I recommend the Samsung T5 or T7 Shield, which provide excellent storage options at a reasonable price.
