With so many things to store on your Mac, you need a reliable storage disk. While in the past Hard Drive Disks (HDDs) have been the norm, they are now being replaced by Solid State Disk drives (SSDs), and this is not without reason.

SSDs are more responsive in terms of their performance. It is faster to copy data from and save to SSDs than HDDs. The prior also operate quietly compared to the latter. If you want a drive that will not be crushing any time soon, then you better get a solid state drive. However, there are many SSDs out there that knowing the best one on your MacBook Pro may be hard.

In this article, you will find details on all the things you need to know about choosing a hard drive. You will also find the best recommendations. Without further ado, let us look at what makes the best SSD for MacBook Pro in 2021.

Considerations when looking for the best SSD for MacBook Pro

What is your Macbook pro controller type?

The disk controller of your MacBook Pro will determine what kind of SSD it is you can use. To find out what the controller for your MacBook is following these steps:

1. Click on the Apple icon at the top left.2. Click on “About this Mac” and then “System report” button.3. In the SATA Express/SATA section, check the Physical Interconnect line. What will be displayed is the SSD controller which can be PCIe or SATA.

To make this even easier for you, here is a reference table you can use to easily determine what the controller in your MacBook Pro is. Use this to determine what the ideal MacBook Pro upgrade for your Mac is.

Hard Disk vs SSD

One of the biggest downsides of hard drives is their speeds. For instance, a HDD rated 5,400 RPM has data transfer speeds of 75 MB/s while that operating at 7,200 has 100MB/s data transfer rate. Even the fast revolving 10,000 RPM HDD has a sluggish data transfer speed of 140MB/s.

On the other hand a SATA 1.0 has data transfer speeds of 1.5Gbit/s which is equivalent to 187.5 MB/s. This is faster than the fastest hard drive yet it is the slowest SSD ideal for the MacBook Pro 2008. You can see the speeds of the other SATA drives from the table above. With speeds of up to 8.0 Gbit/s on the PCIe Gen 3, it is evident that SSDs have unbeatable speeds and speed is good in any device. You will accomplish things faster which save time.

What is Serial ATA (SATA) and PCIe?

These are the two main connection interfaces you will find in MacBook Pros. What are the differences? Serial ATA is an interface that has been around since 2003 and is the most widely used connection. It replaced the PATA connection used in the past. SATA offered faster speeds, native hot swapping and reduced cable size. This kind of connection is supported by many different MacBooks both new and old.

On the other hand, PCIe stands for peripheral component interconnect express. This is a kind of physical interconnect that has been recently developed and is used to plug in SSDs, network and graphic cards. It offers very fast data transfer speeds and better error detection and reporting. However, it is only supported in recent MacBook Pro computers.
