CalDigit Tuff Nano Plus review: A reliable, durable, portable SSD

The CalDigit Tuff Nano Plus is a speedy SSD with an impressive 2TB capacity designed for on-the-go iPad and Mac workflows.

CalDigit makes amazing accessories for Mac and iPad, recently releasing a line of Thunderbolt 4 accessories including the TS4 dock and the Element hub.

While they make headlines for their docks, they also offer several storage solutions. The CalDigit Tuff Nano has been around for a few years, and now the CalDigit Tuff Nano Plus joins the lineup.

Portable storage

Out of the gate, one of the best parts of the CalDigit Tuff Nano Plus is its packaging. It arrives in a plastic box that can double as a storage option.

This reduces waste and provides an extra accessory for your drive.

The box's label can be removed and replaced with one of your choice. These cases can be clearly labeled and organized on a shelf for quick access for heavy media users.

Open the box, and CalDigit includes both a USB-C to USB-C cable and a USB-C to USB-A cable. This can be unnecessary, but it's helpful to keep the second cable in the case should you ever need it for other devices.

The Tuff Nano Plus is a hair over four inches long, two inches wide, and a little over half an inch thick. With the rubber bumper, it weighs 0.22 pounds all-in.

CalDigit uses an all-aluminum enclosure for the Tuff Nano Plus wrapped in a rubber bumper. The bumper covers the corners as well as the USB-C port.

You can remove the cover at any time for a sleeker appearance, though you do sacrifice some of the durability. The Tuff Nano Plus has an IP67 resistance rating with the protective bumper attached.

IP67 means it is sealed off entirely from dust and can be submerged in one meter of water for up to 30 minutes. The USB-C port must be sealed for that water resistance to hold.

As a bus-powered USB-C NVMe SSD, it's perfectly suited for mobile workflows. All current Macs have adopted USB-C as have the iPad Air, iPad mini, and iPad Pro. Regardless of which device you use, the Tuff Nano Plus will work.

Tuff Nano versus Tuff Nano Plus

In many ways, the CalDigit Tuff Nano and Tuff Nano Plus are the same. They have a very similar metal design with a colorful rubber bumper around the outside and are bus-powered over USB-C.

Both have the same IP67 resistance and come preformatted in HFS+. Where they differ is in speed, size, and capacity.

The Tuff Nano Plus is just slightly longer than the Tuff Nano due to the new internal NVMe media. CalDigit only offered the Tuff Nano in 512GB and 1TB configurations, while the Tuff Nano Plus comes in 2TB.

Finally, that updated NVMe SSD and larger capacity result in slightly faster speeds. The Tuff Nano was advertised at 1055 MB/s read speed, while the Tuff Nano Plus is advertised at 1088 MB/s.

As the differences aren't huge, CalDigit continues to offer both versions. The smaller capacities in the Tuff Nano and the higher capacity Tuff Nano Plus.

Format as needed

Out of the box, CalDigit has formatted the Tuff Nano Plus in Apple's HFS format. This has been Apple's go-to file format for years before it started transitioning to APFS.

APFS was designed specifically for the flash-based storage in its latest Macs but can be used with external drives. We ran speed tests both in the default HFS+ format and APFS.

Formatted as HFS+, our CalDigit Tuff Nano Plus scored an 828 MB/s write speed and a 738 MB/s read speed. That's just shy of the advertised 1088 MB/s maximum read speed.

When we reformatted the drive as APFS, the write score jumped to 921 MB/s while the read score stayed nearly identical at 740 MB/s. This score is higher than we saw on the standard CalDigit Tuff Nano.

Should you buy the CalDigit Tuff Nano Plus?

When we reviewed the CalDigit Tuff Nano back in 2019, we loved it. It was exceptionally compact and fast.

Since then, many more portable SSDs have made their way to market.

It's much more competitive than it was back then, and users have many more choices to choose from. Despite that, CalDigit remains at the top of our recommendation list.

The updated CalDigit Tuff Nano Plus is faster while also offering a larger storage size. Users who need a lot of storage on the go needn't look any further.

Pros

• Ultra-fast NVMe SSD media
• Protective rubber exterior
• Carrying case included
• Great read and write speeds
• IP67 resistance

Cons

• Not many color choices
