You can finally buy a Thunderbolt 5 SSD

Following the arrival of the first Thunderbolt 5 cables last July and the first Thunderbolt 5 dock last September, it might finally be time to start upgrading your external storage to take advantage of the increased performance. It’s been a slow rollout for Thunderbolt 5 hardware following its official reveal in September 2023, but companies like Seagate, OWC, and Sabrent finally have SSDs enroute supporting the new standard.

Seagate announced its new Thunderbolt 5 LaCie Rugged SSD Pro5 external drive at CES 2025 this week. The company says it will be available sometime this month in a 2TB version for $399.99 and a 4TB version for $599.99. They’ll offer read and write speeds of 6,700MB/s and 5,300MB/s, respectively.

Like previous LaCie rugged drives, the new SSD comes in a rubber enclosure in blue, black, and orange color options helping it survive drops from heights of up to three meters. It’s also waterproof with an IP68 rating so it can survive a complete dunking to depths of one meter.

There are a few other choices that have been announced, too, though with varying levels of availability. Sabrent, for example, was actually one of the first companies to announce a Thunderbolt 5 SSD last August, but the SSD isn’t out yet. The Rocket XTRM 5 comes in a silicone sleeve for extra protection from falls, and the company says it can reach read and write speeds of 6,000MB/s and 5,000MB/s, respectively. It’s expected to be available in 1TB, 2TB, and 4TB capacities, but is still listed as only being available for preorder through Sabrent’s website.

OWC announced its Envoy Ultra Thunderbolt 5 SSD last September. The company says the external drive is water-resistant, dust-resistant, and crushproof, and offers read speeds of over 6,000MB/s. When it was announced, OWC said the Envoy Ultra would be available in a 2TB version for $399.99 and a 4TB version for $599.99, with shipping starting in late October. The first shipments of the drives sold out, but it’s still available for preorder through OWC’s website with an expected ship date of mid January 2025.

If you’d rather take a DIY approach, several Thunderbolt 5-compatible SSD enclosures have also been announced over the past few months.

However, despite the promised performance improvements, and the year long wait for hardware to finally materialize, upgrading your setup to Thunderbolt 5 might still have a few speed bumps. That’s what Mark Hachman, the Senior Editor of PC World, discovered when trying to get a Maingear ML-17 laptop, Kensington’s Thunderbolt 5 dock, OWC’s Envoy Ultra SSD, and Acer’s Nitro XV5 displays to play nice. The setup was plagued by laggy performance and slow transfer speeds.

It all still felt not quite ready for primetime, Hachman found. “When you buy (or test) bleeding-edge hardware, sometimes you’re the one that ends up with the cuts,” Hachman said.
