Switching files between devices is supposed to be easy, right? In practice, it can be a headache.
After using this dual-connector flash drive for everyday backups and quick transfers, it’s actually pretty practical—though not without a few tradeoffs. It feels solid in hand, works without any drama, and slots right into a mixed USB‑C/USB‑A setup.
- Dual connectors with USB Type-C and USB Type-A ports
- Transfer your files with high-speed USB 3.1 performance
- Features a stylish metal housing and swivel design for added protection
The Lexar D400 makes it almost too easy to move folders between a newer laptop and an older desktop. No adapters, no fuss.
Transfers are quick enough for photos, videos, and work files, but don’t expect absolute consistency with really big batches. The metal swivel design feels sturdy, though if you keep it on a keychain, you might notice some wear after a while.
Overview: Lexar 64GB JumpDrive Dual Drive D400
After a few days of shuffling files between a laptop and a phone, what stands out most is the convenience. The JumpDrive D400 flips between USB‑C and USB‑A, so you can skip adapters and just get on with it.
It’s got a reliable, no-nonsense feel. The metal body shrugs off scratches, and the swivel cover keeps the ends safe in a pocket or bag.
Everyday backups go fast, but it’s not the fastest thing out there if you’re moving massive folders. Still, it gets the job done for most people.
What works well
- Easy switching between modern and older devices
- Sturdy metal housing with a practical swivel
- Consistent performance for routine storage tasks
What could be better
- The swivel can loosen with heavy keychain use
- Speeds vary depending on the device and file size
Dual Device Compatibility
Switching between devices is genuinely effortless with this drive. Files move straight from a USB‑C phone to an older USB‑A laptop—no adapters, no drama.
The swivel design makes the dual connectors feel practical, not clunky. One end for new stuff, one for the old—simple.
That kind of flexibility is a real time-saver, especially when you’re juggling files across platforms. It handled Android, Windows, and macOS just fine in testing, and there weren’t any formatting headaches.
The only catch? The connectors are close together, so if your laptop’s ports are crowded, you might have to wiggle things around. Still, the dual compatibility is a big win for mixed-device setups.
Fast USB 3.1 Performance
Daily file transfers feel snappy—especially for photos and regular documents. The D400 uses USB 3.1, so you’re not left drumming your fingers waiting for stuff to copy.
Write speeds are solid for a little dual‑connector drive. Backups and media transfers don’t drag, though if you’re dumping a massive folder, you’ll need a bit of patience compared to an external SSD.
Performance is pretty consistent across both USB‑C and USB‑A. It’s best with newer devices; older ports, as expected, slow things down a bit.
What stands out
- Smooth performance for everyday transfers
- No noticeable lag when switching between devices
What could be better
- Large write jobs are not instant
- Performance depends heavily on the host port
Secure File Protection
Moving sensitive work files? Security matters. The drive comes with Lexar’s built-in security software, so you can slap a password on private folders without turning file transfers into a chore.
It’s pretty simple to lock down certain files and leave others open for fast sharing. The setup stays on the drive, so it works on any computer without extra installs.
What worked well
- Keeps private files separate from general storage
- Easy to enable and manage during regular transfers
- No noticeable slowdown when accessing protected data
What could be better
- Security tools feel basic and focus on file locking only
- Users who want deeper encryption controls may want more options
Durable Metal Housing
After a few days of tossing it in a bag, the metal casing holds up better than plastic. There’s a reassuring rigidity—no flex, no creaking, and it shrugs off the usual pocket abuse.
The JumpDrive D400 uses a swivel-style cover that shields both ends without making the thing bulky. The moving part rotates smoothly and lines up well, so you’re not left fiddling with a loose hinge.
What works well
- Resists scratches better than expected
- Adds a reassuring weight without feeling heavy
- No loose seams or rattling during use
What could be better
- The metal surface attracts fingerprints
- The swivel can feel cold to the touch in winter
Sleek Swivel Design
It’s satisfying—flick your thumb, and the connector you need pops out with a little snap. The JumpDrive D400’s metal shell resists scuffs and feels solid, not cheap.
The rotating cover protects both ends, so you don’t have to worry about losing a cap. The hinge stays tight, even after a bunch of uses.
It does add a bit of heft compared to plastic, which you’ll notice if you keep it on your keys. And the exposed connector is still, well, exposed when in use—so a little care is smart. But overall, the design is about practicality, not showing off.
User Experience and Practical Applications

Transfers for documents, photos, and backups felt quick. The metal swivel makes it easy to handle and keeps the connectors safe, even when tossed into a bag.
What worked well

Pros and Cons
After some regular use, it’s clear this drive is built for convenience, not flashiness. Here’s what stands out, for better or worse:
Pros
- Easy device switching: Plugs into both USB‑C laptops and old USB‑A ports without adapters. Saves time, makes backups and sharing a breeze.

- Broad compatibility: Works out of the box with phones, tablets, and computers. Handy if you live in a mixed-device household.
Cons

- Speed varies by task: Regular files are quick, but huge transfers take longer. Power users will notice the limits.
- Small form factor trade‑off: It’s tiny—easy to lose if you’re not careful. Probably needs a case or a regular spot in your bag.

Frequently Asked Questions
Questions tend to pop up after a few days of using the drive daily, especially if you’re swapping between a shiny new laptop and some older desktop. The points below come from hands-on use and the sort of concerns buyers actually have.
How to properly use a Lexar Dual Drive with both Type-C and Type-A connectors?
It works best if you let the swivel click fully into place before plugging in. The metal arm rotates smoothly, but lining it up right saves your port from unnecessary strain.
I always ejected the drive before flipping connectors, and honestly, it helped avoid those annoying file errors. Skipping adapters kept things simple and just seemed to cause fewer headaches.
What are the read and write speeds of the Lexar D400 Dual Drive?
In regular use, file transfers felt quick enough for documents, photos, and short videos. Large folders moved along at a steady pace—no stalling, no overheating.
The drive claims read speeds up to 130MB/s, but real results depended on the device. Older ports definitely slowed it down, while newer USB connections got closer to that advertised speed.
How does the Lexar JumpDrive D400 compare in performance to other USB 3.1 flash drives?
Performance matched other mid-range USB 3.1 drives I’ve used. It didn’t blow the doors off, but it also avoided the sluggishness you get from bargain-bin options.
Honestly, the biggest win was convenience. Not needing a dongle saved more time than a slightly faster transfer rate ever could.
Are there any security features built into the Lexar JumpDrive Dual Drive D400?
It comes with Lexar’s DataShield software for password protection and encryption. That made it easy to keep personal files separate if the drive changed hands.
Setup took a quick install step, which might not be everyone’s favorite thing. Once it was running, though, it worked as expected and didn’t slow down normal access.
Can the Lexar 64GB Dual Drive be used interchangeably with Type-C and Type-A ports?
Switching between ports was seamless in testing on laptops, desktops, and even an Android phone. Files stayed accessible, no matter which connector was in use.
The drive handled repeated swaps without any connection drops. That kind of flexibility made it genuinely useful for mixed-device setups.
What is the durability and reliability of the Lexar D400 when used extensively?
The metal housing resisted scratches better than the plastic drives I’ve carried around every day. That swivel design? It actually protected the connectors when I tossed it into a bag or pocket, which is always a relief.
After months of use, I didn’t notice any data corruption. The exposed swivel can loosen up a bit as time goes on, though.
It feels sturdy overall. If you’re thinking about putting it on a keychain, just know that might add some extra wear.
