- TeamGroup PD40 reaches read speeds of 4000 MB/s and write speeds of 3500 MB/s
- The PD40 comes in three large capacities: 1TB, 2TB and 4TB
- The device weighs only 22 grams and looks like a large flash drive.
TeamGroup has introduced the PD40, a small USB4 external drive designed for users who want high performance without paying a premium.
The company has earned a reputation for producing storage that offers solid value, and its devices frequently appear in our roundups of the best SSD options for general users.
The PD40 continues that strategy by offering high transfer speeds over a USB4 Type-C interface while maintaining a simple, compact and easy-to-carry overall design.
Performance and capacity for practical workloads.
The drive achieves sequential read speeds of up to 4000 MB/s and write speeds of up to 3500 MB/s.
This puts it in the same category as more expensive USB4 drives like the MSI Datamag.
It comes in 1TB, 2TB and 4TB versions, although the lack of an 8TB option leaves it behind rivals like the Adata SE940 that already offer greater capacities.
Even with that limitation, the available configurations should still be suitable for prosumers who regularly move large video files, data sets, or development builds between systems.
Size is its most distinctive feature, as the device weighs just 22g and looks like a large flash drive rather than a traditional external SSD.
It combines performance with ruggedness by using a rubber grooved exterior that improves grip and reduces the chance of accidental drops during field use.
This device uses a matte black and deep red finish, which adds a more polished look than typical mini SSDs.
It also includes a hole for hanging bags or keychains, along with a silicone cover for the Type-C port to protect the connector when not in use.
According to TeamGroup, the device is IP54 rated, meaning it offers partial dust and water resistance.
TeamGroup says the PD40 maintains broad compatibility with older USB standards such as USB 3.2 and USB 2.0, allowing it to work on a wider range of devices.
It also supports true plug-and-play operation, allowing users to quickly access files on multiple systems without additional configuration.
In terms of pricing, the company looks set to undercut its rivals, as similar USB4 models remain expensive.
It offers a five-year warranty, reinforcing its durability claims.
Other portable SSDs with similar connectivity and speed, such as the SanDisk Extreme PRO and LaCie Rugged SSD4, from $279.99 and $134.99, respectively.
The TeamGroup PD40 needs to start below $120 to be seen as a more affordable option.
