Rtl-sdr Usb 3.0 Here

Imagine decoding ADS-B (planes), POCSAG (pagers), and APRS (packet radio) all from one recording. A USB 3.0 SDR lets you run multiple virtual receivers (via software like SDR# or GNU Radio) across a wide span simultaneously.

One of the most discussed topics in the SDR rtl-sdr usb 3.0

For a standard RTL-SDR dongle, the default sample rate is usually around 2.4 MHz (Mega-samples per second). At 8-bits per sample (I and Q channels), this results in a data rate of roughly 38.4 Mbps. This fits comfortably within the USB 2.0 bandwidth. Imagine decoding ADS-B (planes), POCSAG (pagers), and APRS

For now, the "RTL-SDR USB 3.0" is largely a phantom product. The real leap happens when you move away from the RTL chip entirely. At 8-bits per sample (I and Q channels),

Direct sampling SDRs (like the RX-888) use high-speed ADCs that sample the RF directly at 64 MSps or more. These require USB 3.0 at a minimum. Without it, the data stream is a firehose that would melt a USB 2.0 port.
