Lexar JumpDrive V400 256GB USB 3.0 Flash Drive – Up to 100MB/s, Black

Speed

USB 3.0, Up to 100MB/s Read

USB 2.0 memory sticks are limited to roughly 30–40MB/s in practice. The V400 uses a USB 3.0 interface and reads at up to 100MB/s, so files open quickly straight from the drive and large folders copy across in a fraction of the time. Write speeds are lower than read speeds, as with all flash drives in this class, and vary with file size and capacity — copying many small files is always slower than one large file. For the full speed, plug it into a blue USB 3.0 / 3.1 / 3.2 port; it still works in older USB 2.0 ports at USB 2.0 speed.

Design

Capless with Keyring Loop

Caps are the first thing to go missing on a USB stick. The V400 avoids the problem entirely with a capless body and an integrated loop at the back, so it can live on a keyring, lanyard or zip pull and be ready whenever you need it. The textured black casing is lightweight and compact enough to sit next to other devices in a laptop’s USB ports without blocking them. It is an everyday drive for students, office work, printing at a shop or moving files between home and work computers.

Compatibility

Works Almost Anywhere

No drivers or software are needed: plug it in and it appears as a removable drive on Windows, macOS and most Linux systems. Because it is backward compatible with USB 2.0, it also works in car stereos, smart TVs, media players and printers that accept USB storage. Larger capacities ship formatted for broad compatibility; if a car stereo or TV does not recognise it, reformatting to FAT32 or exFAT on a computer usually solves it. Lexar backs the JumpDrive range with a manufacturer warranty.

Frequently Asked Questions

How fast is the Lexar V400 in real use?

It reads at up to 100MB/s when plugged into a USB 3.0 or newer port. Write speeds are lower and depend on file size — one large file copies much faster than thousands of small ones. In a USB 2.0 port it runs at USB 2.0 speed.

Will the V400 work in my car stereo or TV?

Usually, yes — it is backward compatible with USB 2.0, which car stereos and TVs use. If the device does not see your music or videos, reformat the drive to FAT32 (for 32GB) or exFAT on a computer, as some players only read certain file systems.

Does it work with a Mac?

Yes. It is plug-and-play on macOS and Windows with no drivers. To use one drive on both Mac and Windows, keep it in exFAT format, which both systems can read and write.

Can I connect it to a USB-C laptop or phone?

The V400 has a USB-A connector, so it needs a USB-C to USB-A adapter on USB-C-only devices. If you mainly use USB-C, a dual-connector drive with both USB-A and USB-C is a better fit.

Is the 256GB version big enough for my needs?

The 256GB V400 suits 4K video projects, large media libraries or full laptop backups. Note that formatted capacity is slightly lower than the label, because part of the space is used for formatting and the drive’s firmware.
