Class A1

The A1 specification was devised to define the performance of a memory card when dealing with random reads and writes. Speaking of linear speed, we mean how quickly one large file is written to the USB flash drive. In the case of random operations, we are talking about juggling data arrays consisting of numerous small files. In the case of a smartphone, these are any game cache files, system files, and application data. So, being installed in a smartphone, A-Data Premier demonstrates excellent performance, practically not inferior in speed to the internal memory of the device.

4K video recording

But video shooting in 4K format is not her forte. At this price, it's not surprising. Its linear write speed rests on a rather modest bar of 25 MB / s, so, unlike many relatives, it did not reach the V30 specification, stopping at V10. Technically, such cards are also suitable for shooting at 4K / 60FPS, but in fact you are not immune from crashes during shooting, dropped frames and artifacts caused by a lack of write speed. Therefore, it is better to limit yourself to the classic Full HD. But reading from the card takes place at a standard speed of 100 MB / s, and CrystalDIskMark confirms these figures.

Protection from any adversity

Given that this is one of the most advanced memory cards in the A-Data range, the company has pumped it to the maximum on all fronts. Its body has an increased margin of safety, is not afraid of water, X-ray radiation, shock and vibration.
