Our Verdict

It’s expensive, and you’ll need a new Mac with an M4 Pro or Max processor to get the full benefits of Thunderbolt 5, but the Rugged SSD Pro5 is the fastest back-up drive we’ve ever seen. Its rugged design is ideal for outdoor work, and makes it an ideal back-up solution for demanding creative users.

Thunderbolt 5 was launched back in 2023 – and was rather overlooked, as it was launched on the same day as the iPhone 15 – but it’s taken quite a while for the technology to arrive in mainstream products such as LaCie’s new Rugged SSD Pro5.

Even Apple has taken its time here too, only introducing Thunderbolt 5 on the new M4 MacBook Pro and Mac mini that were launched at the end of 2024 – and even then, only on the models with the high-end M4 Pro and Max chips.

However, LaCie’s range of Rugged solid-state drives have supported Thunderbolt technology for many years, and their sturdy designs have made them popular with many Mac users and creative professionals.

At first glance the Pro5 looks almost identical to the previous-generation Rugged SSD Pro, which uses Thunderbolt 3 and has been sitting on our list of Best External SSD drives for the last three years. The names are almost identical too, so make sure you look for the Pro5 model if you want the latest Thunderbolt 5 performance for your new Mac.

LaCie

The drive is available with either 2TB or 4TB capacities, so you’ve got plenty of room for large video and graphics files, and while it’s not exactly cheap, the Pro5 is still competitively priced for a high-performance drive aimed at pro users. It’s also worth mentioning that LaCie is now owned by Seagate, so you’ll be directed to seagate.com for information about LaCie products.

In fact, the only visible difference between the two drives is the fact that the Pro5 is wrapped in a dark-blue rubber sleeve, rather than the somber black of its predecessor. That rubber sleeve is designed to provide extra protection for the drive, and the Pro5 is even sturdier than before, with an IP68 rating for water and dust-resistance. This means that the drive is completely sealed to prevent dust and other small particles from getting inside the unit, and LaCie claims that it can survive complete immersion in water up to a depth of 1.5 meters for a full 30 minutes.

LaCie also states that the drive can survive being dropped from a height of up to 3m (10ft) and can even cope with being run over by vehicles weighing up to two tonnes. And, to back up those claims, LaCie provides a five-year warranty for the drive, and offers a one-time use of its Data Recovery Service to try and rescue your data in the event that the drive does become damaged.

That rugged design makes the Pro5 a great option for creative users who need to work outdoors for photoshoots or filming. It’s also highly portable, measuring just 17mm thick, 98mm wide and 65mm deep. The tough design means that it’s a little heavier than many of its portable rivals, weighing 150g – compared to 100g for the older Rugged Pro with Thunderbolt 3 – but you can still pick it up and slip it into your pocket with no trouble at all.

LaCie includes a high-performance Thunderbolt 5 cable with the Pro5 drive, but we did notice that the standard USB-C cable we normally use for our Time Machine back-up drive didn’t provide enough power for the
