Team Group THUSDX128GIV3002 128GB microSDXC UHS-I U3 V30 memory card

High Endurance microSDXC for monitoring

This 128GB microSDXC card belongs to the Team Group High Endurance series and is built for continuous write workloads in professional and residential monitoring systems. It carries UHS-I, U3 and V30 ratings to sustain the steady throughput that long-duration recording demands. The card targets installers and system integrators who need reliable storage for always-on cameras.

Thermals noise and power draw in normal use

Operating voltage ranges from 2.7 V to 3.6 V with no moving parts, so the card runs silently and generates negligible heat inside a camera or recorder. Sequential read reaches 100 MB/s while sequential write is rated at 50 MB/s, keeping bus activity moderate during 4K or Full HD capture. The design is specified to withstand extreme temperatures, shock, water, static electricity and X-ray exposure.

V30 sustained write for 4K recording

Video Speed Class V30 guarantees a minimum 30 MB/s sustained write speed, the single figure that determines whether 4K monitoring footage is recorded without dropped frames. Buyers who need higher sustained write rates or larger capacities beyond 128GB should verify those requirements before selecting this card.
