Upgrade to Larger, Higher Capacity Micro SD Card.

Use Mac PC, Macbook Pro to Clone Raspberry Pi:

Upgrade storage capacity on your Raspberry Pi SD Card. Clone Raspberry Pi OS to Macbook Pro, Mac PC and Copy Image to Larger Micro SD Card without losing any data. Use the Disk Utility application and Etcher on a Mac PC to clone Raspberry Pi SD Card. As a result, use clone backup to Upgrade Raspberry Pi by cloning image to larger capacity Micro SD Card.

Upgrading Raspberry Pi SD Card:

In fact, most Raspberry Pi Kits include 16GB to 32GB Micro SD Cards which is a good starting point. However, it will not be long before many Raspberry Pi owners will need more space. Thankfully, there are more options available, and affordable. For example, upgrading the Raspberry Pi SD Card to 64GB, 128GB or 256GB currently costs between $20.00 and $50.00.

In addition, the Mac software, Disk Utility and Etcher is currently free. As a result, provided you have access to a Mac PC, you may only need to purchase a new Micro SD Card.

I Feel the Need for Speed!

Generally speaking, many of the newer Micro SD Cards are faster. In fact, there are some Micro SD Cards that have an application rating of 2. The application rating for SD Cards is relatively new. However, increases in speed when loading applications such web browsers and office applications are notable. In general, the application 2 type Micro SD Cards have faster read and write speeds. By and large, even a good quality class 10, application 1 Micro SD Card will be faster than most cards found in starter kits.

Why use a Macbook Pro, Mac PC?

In fact, using the Mac PC Disk Utility and Etcher, provides a great way to backup your Raspberry Pi SD Card to an alternate safe location. By and large, using a Macbook Pro, Mac PC with Disk Utility and Etcher is more complex than using your Raspberry Pi.
