- TeamGroup PD40 reaches 4000MB/s read and 3500MB/s write speeds
- The PD40 comes in three large capacities – 1TB, 2TB and 4TB
- The device weighs only 22 grams and looks like an oversized 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 built a reputation for producing storage that delivers solid value, and its devices often appear in our roundup of the best SSD options for mainstream users.
The PD40 continues this strategy by offering high transfer speeds through a USB4 Type-C interface, while keeping the overall design simple, compact and travel-friendly.
Performance and capacity for practical workloads
The drive reaches sequential read speeds of up to 4000MB/s and write speeds of up to 3500MB/s.
This puts it in the same category as more expensive USB4 devices such as the MSI Datamag.
It comes in 1TB, 2TB and 4TB versions, although the absence of an 8TB option leaves it behind rivals such as the Adata SE940, which already offer higher capacities.
Even with that limitation, the available configurations should still suit prosumers who regularly move large video files, datasets, or development builds between systems.
Size is its most notable feature, as the device weighs just 22g and looks like an oversized flash drive rather than a traditional external SSD.
It blends performance with durability by using a rubber grooved exterior that improves grip and reduces the risk 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 hanging hole for bags or key chains, along with a silicone cover for the Type-C port to protect the connector when not in use.
According to TeamGroup, the device is rated IP54, which means it offers partial resistance to dust and water.
TeamGroup says the PD40 maintains broad compatibility with older USB standards such as USB 3.2 and USB 2.0, allowing it to work across a wider range of devices.
It also supports true plug-and-play operation, allowing users to quickly access files across multiple systems without additional setup.
In terms of pricing, the company seems to be undercutting the competition as similar USB4 models remain expensive.
It offers a five-year warranty, which reinforces its durability claims.
Other portable SSDs with similar connectivity and speed, such as the SanDisk Extreme PRO and LaCie Rugged SSD4, starting at $279.99 and $134.99 respectively.
The TeamGroup PD40 needs to start under $120 to be seen as a cheaper option.
