Is the LaCie Rugged SSD 4TB fast enough for video editing?

Yes. Its roughly 950 MB/s read and write speeds handle 4K and even higher-resolution footage when editing directly from the drive over USB 3.2 Gen 2.

It has an IP54 rating for dust and splash resistance and is built to survive drops onto hard surfaces, which is the point of the Rugged line.

Does it work with both Mac and Windows?

Yes. It connects over USB-C and works with both platforms; you may need to reformat it for one or the other depending on how it ships.

Does it need a power adapter?

No. It draws power over the USB-C cable, so it is fully portable.

How does it compare with the Samsung T7 Shield?

Both are rugged USB 3.2 Gen 2 SSDs with similar speeds. The LaCie is bulkier and typically carries a higher price, while the T7 Shield is smaller; choose the LaCie if you want maximum protection and LaCie's recovery service.

Is it worth it over a cheaper portable SSD?

If the drive will travel and take knocks, the rugged shell and recovery plan justify the premium. For desk-bound backup, a plain SSD gives the same speed for less.
