Lexar D50E 256GB Dual-Connector USB Flash Drive with USB-A and USB-C
Product description
The Lexar D50E has a metal housing and a swivel design that keeps its USB-A and USB-C connectors together in one compact drive. Its 256GB capacity suits carrying photos, documents, and other files between devices without packing a separate adapter or cable.
With both connector types on board, it can serve as a handoff drive between a USB-C phone and a computer with USB-A. Transfer speeds are listed as up to 400MB/s read and 360MB/s write for this capacity, actual performance depends on the host device and connection.
Best use cases
The D50E is designed for moving or storing files across devices with different USB ports. For example, someone could copy photos from a compatible phone to the drive, then connect it to a computer with a USB-A port to organize or archive them. Lexar’s free app includes a photo-backup function for iOS and Android, although iCloud content backup is not supported.
The product listing names iPhone 17, Android devices, PCs, and USB devices as compatible. Device support for external storage still matters: the manufacturer notes that some devices may limit a drive larger than 32GB unless it is formatted appropriately. For the advertised 5Gbps USB 3.2 Gen 1 connection, both the computer and cable must support that standard. On USB 2.0, the drive falls back to 480Mbps, so the listed maximum transfer rates should not be expected from that connection.

Lexar lists maximum speeds of up to 400MB/s for reads and 360MB/s for writes. These are manufacturer figures based on internal testing, actual results may vary with the host device. Formatted capacity may also be lower than the stated 256GB.
Strengths
The most practical advantage is avoiding an extra adapter when switching between USB-C and standard USB-A ports. The swivel design keeps both connectors on the drive, while the metal housing gives it a more substantial construction than a basic plastic thumb drive. Its capacity also makes it useful for carrying a collection of files in a small format rather than relying on separate, lower-capacity drives.
Buyer feedback often highlights the build, transfer speed, and convenience of having both connectors. Some also appreciate using it across different devices. Opinions on value are mixed, so the appeal depends on whether the dual-connector format and 256GB capacity solve a real storage or transfer need. Worth considering if you routinely move files between newer USB-C devices and computers with USB-A ports.
When it makes sense
Choose the D50E when a single portable drive needs to bridge USB-A and USB-C devices, and the stated capacity is useful for your files. It is a more flexible fit than a drive with only one connector when your devices use both port types. Not the best choice if your main priority is reaching the advertised top speeds through a USB 2.0 connection, which has a lower stated interface limit. Depending on how you use it, the Lexar app’s photo-backup function may also be useful, but it does not back up iCloud content.
