Choosing a 1TB magnetic portable SSD: what to look for in fast storage

A 1TB magnetic portable SSD is a great option for content creators, vloggers, photographers and iPhone users who want to store large files quickly. With USB-C, a compact design and magnetic attachment, this kind of drive is ideal for use on the go and for recording video directly from a compatible iPhone.

However, not every high-speed external SSD will automatically work well with your devices. Watch out for these common pitfalls:

  • The stated speed is a maximum: speeds of up to 2000 MB/s are only achievable when the SSD, cable and connected device all support them.
  • USB-C alone doesn’t tell you enough: USB-C describes the connector, not necessarily the transfer speed. A USB 3.2 Gen 2x2 SSD needs a compatible port and cable.
  • Magnetic attachment isn’t universal: the magnetic ring is most useful with compatible iPhone models. Check that your case won’t get in the way, too.
  • Not all 1TB is available: the SSD’s operating system and formatting use some of the storage space.

Three specifications to check before you buy

1. Interface, cable and real-world speed

An external USB-C SSD is handy for modern laptops, tablets, cameras and smartphones. However, to reach transfer speeds of up to 2000 MB/s, your device must also support USB 3.2 Gen 2x2. Connect the SSD to a slower USB port and speeds will drop.

According to its product specifications, the DigiEra LPS2000M-2 offers read speeds of up to 2000 MB/s and write speeds of up to 1800 MB/s. These are stated maximums. Actual performance depends on factors such as the source device, cable, file size, temperature and available bandwidth.

If you’re using a MacBook or laptop, it’s worth checking the USB specification of the port first. A short, suitable USB-C cable can also help reduce connection issues when transferring large files.

2. Compatibility with iPhone and ProRes video

If you’re looking for an SSD for ProRes video, there’s more to check than storage capacity alone. According to the product description, the DigiEra SSD supports direct recording to external storage on compatible iPhone 15 Pro and Pro Max models at 4K 60fps ProRes. For iPhone 16 Pro and Pro Max models, it lists 4K 120fps ProRes.

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

  • whether your model supports recording ProRes to external storage;
  • whether your iPhone has enough battery charge and storage management capacity;
  • whether the cable you’re using supports data transfer;
  • whether your phone case weakens the magnetic attachment.

The product specifications state that DigiEra models aren’t compatible with iPhone 14 or older models. The USB-C connector means you can also use the drive with laptops, tablets and other devices, but features such as direct video recording may vary by device.

3. Size, protection and everyday use

A portable SSD should be easy to carry as well as fast. According to the product information, the DigiEra models weigh 1.62 oz, approximately 46 grams, and have an aluminium casing. They’ll fit in a camera bag, coat pocket or tech organiser.

The manufacturer states that the drive is shock-resistant up to 1500G for 0.5 ms and vibration-resistant from 10 to 2000 Hz. Treat these as product specifications, not a guarantee that your data will be safe in every situation. Avoid moisture, prolonged heat and hard knocks. Safely disconnect the SSD before removing the cable, especially while video files are being written.

Frequently asked questions

Does a magnetic SSD work with every iPhone?

No. According to the product information, the DigiEra models discussed here are designed for iPhone 15 and newer models with USB-C. For magnetic attachment and direct ProRes recording, you should also check that your specific model and case are compatible.

Can you always achieve 2000 MB/s?

No. This is a stated maximum speed under suitable conditions. Your laptop or phone’s USB port, the cable, file type and temperature can all reduce the actual speed. A USB 3.2 Gen 2x2 SSD needs a compatible host device.

How long does an external SSD last?

Its lifespan depends on write workload, storage conditions, heat and everyday use. Always keep important files available in at least one other location. A shock-resistant SSD can offer extra protection against mechanical impact, but it isn’t a substitute for a backup.
