Quick Overview on Using External Drives with MacBook Pro

There are a few key things to know about using external drives with a MacBook Pro:

The steps to use an external drive with a MacBook Pro are very simple. We’ll cover the details in the sections below.

External Hard Drive Compatibility with MacBook Pro

When choosing an external hard drive for your MacBook Pro, you’ll want to make sure it is compatible. Nearly all external drives today are designed to work with both Windows and Mac, but there are few considerations to keep in mind:

Connection Type

The most important factor is the type of connection the external drive uses to interface with your MacBook Pro. Here are the most common types of connections:

  • USB 3.0 or USB-C – The rectangular USB-A ports used by most external hard drives are compatible with any MacBook Pro. For fastest speeds, use USB 3.0 compatible drives.
  • Thunderbolt – Thunderbolt 1, 2, or 3 ports are available on many MacBook Pros. Thunderbolt provides very fast transfer speeds.
  • USB-C – USB-C connections are oval shaped and support the new USB 3.1 standard. These are the fastest interface for new MacBook Pros.

As long as the external hard drive connects via one of these types of ports, it will be compatible with your MacBook Pro.

Formatting

For full compatibility with your MacBook Pro, the external drive needs to be formatted properly.

The most common file system to use for external hard drives on Macs is Mac OS Extended (HFS+). This format allows you to use the drive for Time Machine backups.

The newer APFS file system can also be used on external drives formatted for Mac. This is the default file system used for internal SSDs on newer Macs.

When you connect the blank external drive to your MacBook for the first time, you’ll be prompted to format the drive. Be sure to choose one of these two Mac compatible formats to get full usability with Time Machine backups and efficiency with Mac file storage.

Power Source

Some external hard drives draw all the power they need from the USB or Thunderbolt cable connection to your MacBook Pro. But some larger capacity and higher performance drives may need their own power adapter in addition to the data cable.

Check if your drive requires external power connections. If so, make sure you have an appropriate power adapter before connecting the drive to your laptop.

Uses for an External Hard Drive with a MacBook Pro

There are several common ways to use an external drive with your MacBook Pro:

Extra Storage Space

One of the main reasons to get an external drive is for expandable long term storage. Photos, videos, music libraries, documents, and projects can quickly fill up the internal SSD storage on your MacBook. Having an external drive gives you a vast amount of extra space to work with these large files.

For example, storing your entire iPhoto or Lightroom photo library on an external drive rather than the main internal drive saves a ton of space. Just connect the external drive when you need to access the files, and disconnect when you are done.

Time Machine Backups

Another popular use for external drives on MacBooks is to use them as a backup drive for Time Machine.

Time Machine is the built-in Mac backup software. It allows you to periodically backup your entire Mac drive or select folders to the external drive. That way you have a bootable backup handy in case your main drive fails or needs to be erased.

Dedicate an external hard drive just for Time Machine backups to always have a copy of your important files.

Transporting Files

Having data on an external drive also allows you to easily transport files between different computers. Plug the drive into your MacBook Pro, copy over any files you need, then disconnect and plug the drive into another Mac or PC.

Large video and photo project files can especially benefit from being kept on a portable external drive like this.

Bootable MacOS Install

Finally, you can even create bootable installations of MacOS on an external drive. This allows you to plug the external drive into any Mac and boot from it. That way you can troubleshoot problems on the main MacOS system, or install MacOS on multiple computers easily.

Choosing the Best External Hard Drive for MacBook Pro

With so many drives available from hard drive manufacturers like Seagate, Western Digital, LaCie, Samsung, and others, how do you choose the right one?

Here are the most important factors to consider when shopping for an external hard drive for your MacBook Pro:

Storage Capacity

External hard drives come in sizes from 1TB up to 10TB or more. Consider how much extra space you need now, and what you may need in the future before settling on a capacity.

Drive Speed

Faster drives enable quicker file transfers and system performance. 7200RPM spinning hard drives are the minimum, while Solid State Drives (SSDs) are blazing fast. Look for drives with USB 3.0/3.1, Thunderbolt, or USB-C interfaces.

Portability

If you plan to transport the drive frequently, smaller portable form factors with durable construction are important.

Single vs Dual Hard Drives

Dual hard drive based RAIDs can increase speed. Or allow instant backups by mirroring data.

Brand Reputation

Stick with major reputable brands like WD, Seagate, and LaCie for the highest quality and reliability.

Warranty

Look for at least a 1 to 3 year warranty from the manufacturer to cover any potential issues.
