Weekly Apple Mac Repair Requests. Week 2 Part 1. Updated 2023.


Good day ZA Support Readers


This past week we received some requests for upgrades.


The Reason for upgrading requests

Most of the time the complaint is that the Mac is slow and that upgrading the macOS can not be done due to a lack of memory.

Here follow a general discussion regarding upgrading your Mac with an SSD.


Solid-state drives (SSD) are faster than hard drives but not all SSDs are the same.

The question to be answered is whether to replace your hard drive with an SSD and which one to choose because they come in different sizes, have different speeds, and cost different prices.

It is also important to understand what kind of SSD will suit your needs.


Key differences between NVMe and SATA SSDs:

– The method of communication that SSDs use can either be NVMe or SATA.

– NVMe drives are faster than SATA drives.

– NVMe SSDs are usually found in M.2 form factor whereas SATA SSDs can take the form of 2.5″ or M.2 drives.

– You need to check if your Mac supports NVMe or SATA before buying.


Read-write speed differences:

– NVMe can deliver a read-write speed of 2000MB per second in comparison to the SATA SSD with 600MB per second.

– SATA SSDs have a maximum speed of 600 MB per second, while M.2 can hit 4 GB per second.

– An SSD with at least 500mb/s sequential read and write speed is recommended and will be fast enough for most tasks.

– If you need more for complex things you should look into SSDs rated 2000 or 3000 mb/s speeds.


A major problem with SATA SSDs is the speed of SATA connections and a solid-state drive will always be faster than a Hard Drive however the NVMe technology will always pass the speed caps of SATA devices.

So the main differences between NVMe and SATA are cable clutter and speed.

No matter what SSD you upgrade to you will experience a leap in performance.


In part 2 we will discuss RAM upgrades.
