TWSC has introduced the TC301, a tiny USB-C flash drive built for in-car monitoring and video capture, with a metal body, a short T-shaped design, and specs that look deliberately aimed at dash cams rather than desktop use. The company has not announced pricing yet, but it has put the emphasis squarely on endurance: 24/7 cyclic recording, overwrite support, and a wide temperature range for life inside a parked vehicle that gets cooked, frozen, and restarted more often than any sane office drive.
That positioning makes sense. Automotive storage is a niche, but a growing one, because continuous recording is exactly where ordinary consumer USB sticks tend to give up first. TWSC is basically selling a calmer, tougher alternative to the throwaway flash drives people keep sacrificing to dash cams.
TWSC TC301 size, speed and storage
The TC301 measures 26.1 x 16.1 x 16 mm and comes with 128 GB of TLC NAND flash memory. TWSC says sequential read speed reaches up to 320 MB/s, while sequential write speed goes up to 255 MB/s. For a device this small, that is plenty fast enough for recording and moving video files without making the hardware the bottleneck.
- Interface: USB-C
- Capacity: 128 GB
- Sequential read: up to 320 MB/s
- Sequential write: up to 255 MB/s
- Operating temperature: -25 to +85 °C
- Storage temperature: -45 to +85 °C
Built for heat, cold, and constant overwrites
The temperature specs tell you almost everything about the target audience. A storage device that can survive from -45 to +85 °C in storage and keep operating from -25 to +85 °C is not trying to win a style contest; it is trying to live in a car year-round and not complain.
TWSC’s decision to stress endurance also fits a broader trend in vehicle electronics: more cameras, more always-on recording, and less patience for removable media that wears out too quickly. The TC301 is small, plain, and very specific, which is probably exactly what buyers in this category want.
Price and availability are still missing
One obvious omission remains: TWSC has not said how much the TC301 will cost. That leaves the spec sheet doing all the heavy lifting for now, which is fine if the company is courting fleet operators or dash cam enthusiasts, but less helpful for anyone trying to compare it directly with mainstream USB drives.
If the price lands in the right range, the TC301 could slot into a fairly practical corner of the market: compact, rugged storage for cars that spend their lives recording, rewinding, and recording again. If it does not, it becomes another neat idea looking for a buyer.
