Best SSD for MacBook Pro (Internal Upgrade): Top 3 Choices

When most of us think of where our Macs store data, we are used to saying "the hard drive".

But the truth is, not all drives are physically spinning HDDs anymore, and the Solid State Drive (or SSD) is becoming an increasingly common upgrade for MacBook Pros of all ages.

Because SSDs have a number of advantages compared to HDDs, they are more speedy, reliable and quieter — yes, you won't hear the click sound from a spinning hard drive. However, SSDs are also a little bit expensive than HDDs though the price difference is diminishing.

In this guide, we'll walk you through picking the best SSD drive to upgrade your MacBook Pro's old hard drive or existing SSD and point out how we chose the favorite products along the way.

Quick Summary

Need a brief summary of our top picks? Here's the best SSD replacement for your MacBook Pro depending on your specific needs.

Who Should (& Should Not) Get This?

It's a digital world, and we all like to have the shiniest gadgets on the market. But do you really need to install a new internal flash storage and dump the old hard disk drive? Well, it all depends and here are our suggestions.

You should consider upgrading your MacBook Pro with an SSD if:​

  • You work with large files regularly.
  • Your MacBook starts up very slow or performs sluggishly in general. This is common for old MacBook Pros such as 2009, 2010, 2011 and 2012 models.
  • The internal hard disk drive is showing its age and might die out any day. Here's a guide that shows how to determine if it's failing.
  • You often use resource-intensive apps such as Adobe Photoshop for photo editing, or Premiere Pro for video editing, etc.
  • You need the greater reliability of file storage or want to minimize negative experiences with overheating and potential damage.
  • You want to upgrade your MacBook without purchasing an entirely new machine.

You may not need an SSD replacement if...

  • You mainly use the Internet and document editing functions on your Mac and do not make use of heavier applications.
  • You use your Mac fairly carefully or do not keep important or sensitive files on the drive.
  • You are using a new MacBook (with Retina display), because "removing the SSD is possible, although it's not an easy job. For starters, the bottom aluminum side is harder to remove. Then, the SSD is kept in place under the speaker module and has a very strong tape covering the interface port." as Chris Smith pointed out in BGR.

Buying an SSD for MacBook Pro: What to Consider?

Capacity

When making a purchase, you may find yourself willing to compromise on storage capacity because of the cost compared to an HDD. Don't do this! Because storage capacity is a key factor that determines how much use you get out of your new drive, and as computers progress, you're going to want to have the space to keep up. Additionally, using external drives can slow down your Mac, so it's best to splurge for extra space now rather than regret it later.

Reading and Writing Speed

Every disk drive is rated with a certain set of speed that describes how fast it can read and write files. The range of a good product usually stays between 500MB/s and 550MB/s. The higher these numbers are, the better. Please note that the advertised numbers are not representative of real-world conditions though, in which you'll probably experience speed about two-thirds of those rated.

Memory Type - MLC and SLC

SSDs have two types of memory: multi-level cell and single-level cell. The first is cheaper to make and stores more information, but the later has a lower rate of error. However, some SSDs come with error-correcting features to minimize this difference, so it's up to you to decide which best fits your needs.

Reliability

While judging a book by its cover is generally frowned upon, when it comes to flash storage, it's perfectly acceptable to judge performance and reliability from the brand name alone. Well-known companies usually have good reputations for reliability and quality control of their products, and you'll want that name-brand security when it comes to something as critical to daily functions.

Its energy efficient features will protect your MacBook from overheating or draining of the battery. This is an SSD that should meet most users' needs.

Also, the drive includes energy adaptive features to prevent overheating and excessive battery use — this is especially helpful if you're still using an old MacBook with a battery under fairly poor conditions.
  • Cons: It's not the fastest drive on the market and some users may need a spacer to make this fit correctly inside their MacBook.

SanDisk is a world-famous storage solution provider that offers many types of products especially memory cards, flash drives, etc. If you're a photographer, chances are you're using or have used an SD card manufactured by SanDisk. What you may not know is that the company also offers solid state drives.

Useful Tips and Tricks

Whenever you consider making any significant changes to your MacBook Pro, it's always a good practice to make sure you have a recent backup of all the important files.

Using a MacBook Pro with Retina display (most models after the year 2013)? These Macs don't officially support being taken apart so you should consider carefully whether or not you want to go through with it.
