Products
Cards and drives. One engineering standard.
Memory cards and solid-state drives built around confirmed standards: capacity, interface and the performance figures that define behaviour under sustained load.
Engineering
Every mark has a meaning.
The symbols printed on a STINGRAY card are not decoration. Each one is a published standard describing exactly how the card behaves when a device is writing at full rate.
- 256 GB
Capacity
Total addressable storage on the card.
Hours of 4K footage or tens of thousands of stills before a swap.
- UHS-I
Bus interface
The Ultra High Speed bus the card runs on.
Determines the ceiling for transfer rates on a compatible host.
- C10
Speed Class
Minimum sustained write of 10 MB/s.
The baseline for Full HD recording without dropped frames.
- U3
UHS Speed Class
Minimum sustained write of 30 MB/s on a UHS bus.
Headroom for 4K capture and high-bitrate photography bursts.
- V30
Video Speed Class
Minimum sustained write of 30 MB/s, defined for video.
A recording guarantee, not a peak figure — takes survive.
- A2
App Performance Class
Random read and write performance for running applications.
Apps and systems installed on the card stay responsive.
Applications
Where the card decides the outcome.
Cameras, drones, phones and equipment all wait on the same thing: how fast data lands on the card.

Technology
Performance is more than a number.
A storage product is defined by how it behaves under load: sustained writes, retrieval speed, class guarantees and the interface it runs on.
- 01
Read speed
How quickly stored data is retrieved by the host device.
- 02
Write speed
How quickly data is recorded — the limit for continuous capture.
- 03
Capacity
How much data the device holds, matched to file sizes and workflow.
- 04
Speed class
The guaranteed minimum sustained write performance.
- 05
Compatibility
Format, bus interface and file system supported by the host.
