This flash drive is incredibly convenient with both USB-C and USB-A connections. It makes transferring files between newer laptops, desktops, and even tablets seamless—no need for adapters. The sliding mechanism feels sturdy and protects the connectors when not in use. Speeds are fast for everyday use, with quick transfers for large files like photos, videos, and project backups. The 256GB capacity gives plenty of space without having to juggle multiple drives. Compact, versatile, and reliable—it’s become my go-to for moving and storing files across devices. Read more

High Capacity and Dual Functionality, Minor Durability Concern "The Lexar 512GB JumpDrive Dual Drive D400 is an impressive flash drive that offers both versatility and convenience. I love the dual functionality of Type-C and Type-A, which makes it incredibly easy to transfer files between different devices, from laptops to phones, without needing an adapter. The 512GB capacity is fantastic, offering ample storage for large files, photos, and videos, and the USB 3.2 speeds mean that transfers are quick and efficient. The design is sleek and compact, making it easy to carry around in a pocket or bag. I also appreciate that it works seamlessly across different platforms, whether I’m using it on a Mac or a Windows PC, and even with my Android phone. It's especially useful for anyone who needs to frequently move files between older and newer devices. The only reason I'm giving it 4 stars instead of 5 is that the casing feels a bit flimsy compared to other drives I’ve used. I’m a little concerned about long-term durability, especially with frequent plugging in and out. It would have been great if it had a sturdier build or some sort of cap to protect the connectors. Overall, though, this is a solid, high-capacity drive that offers fast performance and excellent compatibility with multiple devices. It's a great choice for anyone who needs both USB-C and USB-A in one convenient package." Read more

Definitely a slick design with the easy flip from USB C to USB A. Most importantly it works great and it's pretty quick for a thumb drive. Read more

Was a big fan of Lexar until this last year. The failure rate was one in three this year. This particular model has proven to be quite satisfactory. Read more

Great job lots capacity very fast however, on a keychain, it doesn’t last very long. That’s the only reason it’s not a five star otherwise it’s great good looking sleek and works well. Read more

Only just got this so no comment about durability, but wow, this thing feels well built. The housing is all metal and the swivel action has three detents (magnetic?): in each “closed” positions plus the “both open / T” position. That was a pleasant surprise! I was expecting a flimsy plastic dongle. The rounded edges and surface finish are also nice in the hand. I got this specifically for making file transfers to clients, and I like that when I hand this to a client it sends a message of quality about me and my operation. Details matter! Read more
