Choosing a 1TB magnetic external SSD: what to look for in fast USB-C storage?

A 1TB magnetic external SSD can be useful for videographers, photographers and iPhone users who want to store large files on the go. Think 4K video, ProRes recordings, RAW photos and backups from a USB-C laptop. However, not every compact drive is automatically right for your workflow.

The main problems often stem from three misunderstandings:

• A high speed on the packaging doesn’t mean every device will reach it. An SSD rated at up to 2000 MB/s needs a compatible USB 3.2 Gen 2x2 port, cable and host device.
• Magnetic attachment doesn’t mean universal compatibility. The connector may be USB-C, but direct recording features vary between smartphones and apps.
• An SSD isn’t a complete backup strategy. If your drive is lost, damaged or files are deleted by mistake, it’s wise to keep a second copy on a computer, NAS or another drive.

The key specifications of a 1TB magnetic external SSD

1. Check the USB version and the port

An external USB-C SSD uses a USB-C connector, but transfer speeds are also determined by the USB standard. According to DigiEra’s product information, a USB 3.2 Gen 2x2 SSD can support read speeds of up to 2000 MB/s and write speeds of up to 1800 MB/s.

In practice, speeds may be lower if:

• your laptop only supports USB 3.2 Gen 1 or USB 3.2 Gen 2;
• you’re using a cable that isn’t suitable for the required data speed;
• the SSD is connected through a hub or adapter;
• large files are written over an extended period and the internal cache fills up.

So check the specifications of your iPhone, laptop, tablet or camera as well as the SSD. A USB-C connector alone doesn’t tell you enough.

2. Check compatibility with iPhone and ProRes

For users looking for an SSD for iPhone 15 and iPhone 16, direct recording to external storage is an important consideration. According to the product description, the DigiEra LPS2000M series supports direct ProRes recording on compatible iPhone models. Its stated support includes 4K at 60 fps on iPhone 15 Pro and Pro Max, and 4K at 120 fps on iPhone 16 Pro and Pro Max.

This doesn’t mean every iPhone 15 or iPhone 16 version has the same capabilities. Check:

1. whether your model supports ProRes;
2. whether the app you’re using allows recording to external storage;
3. whether the SSD is connected directly;
4. whether the cable supports data transfer;
5. whether there’s enough free space on the SSD.

An SSD for ProRes video is particularly useful if you regularly record long, large video files. For everyday photos or documents, a cheaper USB stick or HDD may be enough.

3. Consider the size, attachment and protection

A magnetic SSD is especially handy when you want to film without an extra clip or holder. According to the stated product specifications, the DigiEra LPS2000M-3 weighs 1.62 oz, or approximately 46 grams, and has an aluminium casing. Its built-in magnetic ring is designed to attach to compatible iPhone models.

Keep the following points in mind:

• A magnetic ring won’t necessarily work properly through every case.
• A loose cable can pull on the USB-C port while you’re filming.
• A shock-resistant external SSD isn’t the same as a waterproof SSD.
• The stated shock resistance of 1500G at 0.5 ms is a product specification, not a guarantee against damage in every real-world situation.

Always keep important files in at least two locations. Also use the safe eject function before disconnecting the SSD.

Frequently asked questions about 1TB magnetic external SSDs

Does a magnetic SSD work with every iPhone?

No. Check your iPhone generation, exact model, USB-C support and recording app. According to DigiEra’s product information, the magnetic SSD mentioned is designed for iPhone 15 and newer models, not iPhone 14 or earlier models.

Is 1TB enough for 4K ProRes video?

It depends on the resolution, frame rate and recording length. 1TB gives you room for several large projects, but ProRes files use up storage quickly. So plan to transfer files regularly to a computer or a second backup drive.

Does a fast external SSD use more power?

When used with a mobile device, an SSD is generally powered via USB-C. Actual power consumption varies depending on the device, cable and how you use it. During long recordings, your iPhone or laptop battery may drain faster. Connecting directly without an unnecessary hub can help reduce connection issues.
