Choose 2TB for everyday backups, photos and documents, or 4TB when videos and larger media libraries need more room. USB-C makes it easy to connect to compatible Windows and Mac computers, while power comes straight from the connected device. Current LaCie Mobile Drive models offer transfer speeds of up to 130MB/s, making them a practical choice when portable capacity matters.

Seagate external SSDs: Know what to buy

If you’ve searched for a Seagate external SSD, check the storage type listed on each product before you buy. SSDs use flash memory and have no moving parts. The LaCie Mobile Drive models featured here use hard-disk storage instead. A portable HDD can give you plenty of space for backups, photos and videos, while an SSD is usually faster and better suited to regular large file transfers.

2TB or 4TB? Give your files room to grow

A 2TB Seagate drive can suit everyday photos, documents and backups. A 4TB model gives you more space for video, large media libraries and long-term storage. Both capacities are available in our LaCie Mobile Drive range.

USB-C, formatting and backups made simple

LaCie Mobile Drive connects through USB-C and works with compatible Windows and Mac systems. It comes formatted as exFAT, which allows files to move between both platforms.

If you want to use the Apple Time Machine, you may need to reformat the drive first. LaCie Toolkit can also help with one-click or scheduled backups. Remember that formatting removes existing data, so copy anything important somewhere safe before you start.

Frequently Asked Questions

It depends on what you need. An SSD is usually faster, smaller and more resistant to knocks because it has no moving parts. A hard drive can offer more storage for the money. That makes an HDD useful for large backups and archives, while an SSD can make more sense for frequent transfers, gaming or travel.
Start with the amount of data you already have. 2TB can give you plenty of room for photos, documents and normal backups. A 4TB drive can be more practical for large video collections or several computer backups. Leaving spare space also means you’re less likely to need another drive soon.
Yes. The drive supports compatible Windows and macOS systems. It comes formatted as exFAT, which can be read and written by both. If you change the format later, check that your chosen file system works with every computer you plan to use.
Yes, but reformatting may be needed. Seagate advises that the drive may need a Mac-friendly format before you use it with Time Machine. Formatting erases the files already stored on the drive, so make a separate backup first.
No. LaCie Mobile Drive takes its power through the USB-C connection, so you don’t need to carry a separate mains adaptor. That keeps the setup simple when you’re working away from your desk.
If faster transfers, lower weight or a drive with no moving parts matters more than maximum capacity for the money, solid-state storage may suit you better. Browse our wider SSD storage range to compare portable and internal options.
