USB-C: Future Compatibility

USB-C 3.1 clearly makes the most sense going forward, which is why we built the highest level of performance and compatibility into the latest LaCie d2 Professional. Take advantage of the fully reversible USB-C cables which can be used on any PC or Mac. You can expect up to 260 MB/s for all your epic workflows along with fast file transfer rates of up to 5 Gb/s.

Solid Components. Solid Investment.


Forged from a single sheet of aluminium, the enclosure provides uncommon rigidity for long-term durability.


The whisper-quiet fan and heat-dissipating aluminium enclosure pull heat away from the HDD, keeping it running fast and healthy.


5-Year Limited Warranty

Choose with confidence. The LaCie d2 Professional is backed by the industry’s most generous warranty.

VERY sturdy, well built and good for Mac.

Works well, can be portioned as expected for time machine etc. Very, very good Build quality... I knocked it over by accident... it dented the desk! No complaints, just my clumsy-ness. Great purchase rather than buying extra apple built in storage. (Im running Mac mini m 1 2020)
