Check your device supports microSDXC UHS-I and V30

Before ordering, verify that your host device accepts microSDXC cards and can utilise UHS-I speeds with a V30 video speed class rating. The card is also compatible with microSDHC, microSDXC UHS-II and microSDHC UHS-II slots, but will operate at the host's maximum supported speed. Ensure your device firmware is current for full capacity recognition.

Rated for extreme temperatures with no moving parts

The card operates from -25°C to 85°C and survives storage from -40°C to 85°C. With no moving parts it runs silently and draws minimal power during read and write cycles. Read speeds reach 170MB/s and write speeds reach 90MB/s, sustaining performance across the temperature range.
