256GB USB 3.2 Flash Drive

The TCELL 4K Fire is a 256GB USB 3.2 Gen 1 flash drive with a Type A connector. Sequential read and write speeds reach up to 400MB/s, and 4K random speed reaches up to 30MB/s. It is aimed at designers, gamers and Tesla owners who need fast portable storage for dashcam Sentry Mode footage. The aluminum alloy casing aids heat dissipation.

Plug-and-play installation with UASP support

The drive works as a standard USB mass storage device on compatible hosts. UASP support reduces CPU overhead during transfers when the host operating system and controller support the protocol. Windows 8, Windows 10 and macOS 10.8 or later are listed as supporting UASP. If the host treats the drive as a fixed disk rather than removable media, some operating systems may not offer a safe-eject option. Ensure the port supplies sufficient current to avoid interference with other devices.

256GB capacity for media and dashcam loops

The 256GB capacity holds large photo libraries, video projects or continuous Tesla Sentry Mode recordings. Transferring 1000 pictures takes roughly 18 seconds under ideal conditions. Sustained 400MB/s throughput depends on the host controller, cable quality and file mix; random 4K workloads run at up to 30MB/s. The drive will not suit users who need more than 256GB of portable space or who require a Type C connector without an adapter.

Questions about this item

How can I confirm the drive is delivering the advertised 400 MB/s read and write speeds after setup?

Run a benchmark tool such as CrystalDiskMark on a USB 3.2 Gen 1 port; sequential results should approach 400 MB/s for both read and write, and 4K random speeds should reach around 30 MB/s.

What is included with the 4K Fire 256 GB drive and what must I provide separately?

The package contains the USB 3.2 Gen 1 Type-A flash drive with aluminum alloy casing and Swarovski crystal accent; you must supply a host device with a USB 3.0 or 3.2 port and an operating system that supports UASP (Windows 8, Windows 10, macOS 10.8 or later).

Which capacity version of the 4K Fire series should I choose for Tesla Sentry Mode and large game libraries?

The 256 GB model stores roughly 1 000 photos in about 18 seconds and provides ample space for dash-cam footage and game installs; select this capacity if you need high-speed external storage in a single compact stick.
