- TeamGroup PD40 achieves read speeds of 4,000 MB/s and write speeds of 3,500 MB/s
- The PD40 is available in three large capacities: 1TB, 2TB and 4TB.
- The device weighs only 22 grams and looks like an oversized USB stick
TeamGroup introduced the PD40, a small USB4 external drive designed for users who want high performance without paying extra.
The company has built a reputation as a storage producer that offers solid value, and its devices frequently appear in our roundup of the best SSD options for general users.
The PD40 continues this strategy by offering high transfer speeds via a USB4 Type-C interface while keeping an overall design simple, compact and user-friendly.
Performance and capacity for practical workloads
The drive achieves sequential read speeds of up to 4,000 MB/s and write speeds of up to 3,500 MB/s.
This puts it in the same category as more expensive USB4 units like the MSI Datamag.
It’s available in 1TB, 2TB and 4TB versions, although the lack of an 8TB option leaves it behind competitors such as the Adata SE940 which already offer higher capacities.
Even with this limitation, the available configurations should still be suitable for prosumers who regularly move large video files, datasets, or development builds between systems.
Size is its most distinctive trait, since the device weighs just 22g and resembles an oversized flash drive rather than a traditional external SSD.
It combines performance and ruggedness using a grooved rubber exterior that improves grip and reduces the risk of accidental drops during field use.
This device uses a matte black and dark red finish, which adds a neater look than regular mini SSDs.
It also includes a hanging hole for bags or key rings, as well as a silicone cover for the Type-C port to protect the connector when not in use.
According to TeamGroup, the device is rated IP54, 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 across multiple systems without additional configuration.
In terms of price, the company seems ready to compete with its competitors, as similar USB4 models remain expensive.
It offers a five-year warranty, which backs up its durability claims.
Other portable SSDs with similar connectivity and speed, like the SanDisk Extreme PRO and LaCie Rugged SSD4, start at $279.99 and $134.99, respectively.
TeamGroup PD40 needs to start below $120 to be considered a cheaper option.
