What this card is and who it suits

The Team Group APEX SD7.1 is a 512 GB microSDXC memory card built to the SD 7.1 specification. It uses a PCIe Gen3 x1 lane with NVMe 1.3 protocol to reach up to 800 MB/s read and 700 MB/s write when paired with a professional card reader. The card carries A1, U3, UHS-I and V30 speed class ratings and operates from 0 °C to 70 °C. It is intended for users who need fast storage for 4K or 8K capture and high-performance gaming on devices that support the SD Express interface.

What the SD Express interface changes

On hardware that implements the SD 7.1 microSD Express slot, the card delivers sequential speeds far beyond the UHS-I ceiling. In legacy UHS-I slots it falls back to a maximum of 100 MB/s read and 90 MB/s write, so existing handheld consoles and mobile devices still benefit from the A1 random-access rating but cannot use the PCIe lane. The exFAT file system is pre-formatted for broad device recognition.

Practical limits of the SD 7.1 standard

Full 800 MB/s read and 700 MB/s write are only available when the host device provides a native SD Express slot and a professional-grade reader; standard UHS-I readers cap throughput at the lower UHS-I figures. Buyers whose devices lack an SD Express slot will not see the advertised peak bandwidth. The card weighs 1 g and measures 72 x 24 x 4.6 mm, fitting the standard microSD form factor.

Questions about this item

Does the APEX SD7.1 microSD Express card need any maintenance or firmware updates over time?

No maintenance or firmware updates are required; the card is a solid-state device with no moving parts and relies on the host device for any controller-level management.

What speed limit appears first during sustained heavy write workloads on this card?

In UHS-I devices the write speed caps at 90 MB/s; with SD Express readers the 700 MB/s ceiling is the limiting factor.

How much heat or power draw should I expect when the card runs continuously at full speed?

Operating temperature range is 0 °C to 70 °C and voltage spans 2.7 V to 3.6 V; the card draws minimal power and stays within spec during all-day use.
