Kingston microSD UHS-I U3 128 GB (SDCA3/128GBSP)

The name of Kingston is known far beyond the United States, where the headquarters of the brand is located, which has found popularity in the field of production of all kinds of storage devices. One of the smallest high-speed drives in the company's lineup is Kingston microSDXC UHS-I U3 — a memory card adapted for ultra-high resolution video shooting.

High speed

The UHS-I U3 marking, “tattooed” on the “body” of the model in red letters, clearly hints at the ability to quickly operate large amounts of data. It indicates a guaranteed minimum file write speed of at least 30 Mbps. In parallel, the Kingston microSDXC UHS-I U3 reports the outstanding speed characteristics of the V30 video recording class assigned to the drive.

Full compliance

According to passport data, files are transferred from a flash drive at a speed of up to 90 MB / s, and data is written to it at 80 MB / s. In fact, the indicated speed indicators of the model fully correspond to the claimed values. The speed sags at times, except when transferring a large volume of small files.

Quality assurance

The memory chip is "packed" in a case with protection against water, shock, vibration, X-rays and resistance to temperature extremes. The quality assurance is provided directly by the manufacturer, on behalf of which a lifetime limited product warranty is provided. In addition, the drive is often equipped with an adapter for an "adult size" SD, which allows you to use the flash drive not only in smartphones and action cameras, but also on board serious DSLRs with reporter inclinations — the model handles with serial photography no worse than with 4K video recording.
