SAMSUNG microSDXC T7 1TB memory card

1TB microSDXC UHS-I card

The Samsung microSDXC T7 provides 1TB of storage for mobile phones, tablets, action cameras, 360° cameras, drones, laptops and gaming consoles. It uses a UHS-I interface and delivers read speeds up to 170MB/s. Speed class ratings are U3, V30 and A2. The card weighs approximately 0.25g and measures 0.590 x 0.43 x 0.039 in.

Who this suits; who should look elsewhere

This card suits users who need high-capacity removable storage for 4K video capture or large app libraries on devices with a microSDXC slot. The A2 rating supports faster app loading on compatible hardware. Buyers whose devices only accept full-size SD cards or who require UHS-II or UHS-III bus speeds for sustained write workflows should look elsewhere.

Deciding spec: UHS-I interface

The single specification that decides fit is the UHS-I interface combined with U3, V30 and A2 speed classes. This guarantees a minimum sequential write of 30MB/s and application performance class 2 for random IOPS. Verify that your host device supports microSDXC and UHS-I to reach the rated 170MB/s read and sustained write performance.
