The Nanoflash recorder weighs approximately nine ounces and draws about six watts of power.
The Nanoflash can be configured to pass through HD-SDI video without introducing delay.
Nanoflash outputs video in 8-bit format and supports bitrates from 50 Mbit up to 280 Mbit per second.
Nanoflash stores recordings in QuickTime container format, enabling direct ingest without format conversion.
The Nanoflash is considered more suitable for Steadicam work compared to the Hyperdeck Shuttle 2 due to its smaller size and weight.
The Hyperdeck Shuttle 2 consumes less power than the Nanoflash and offers bidirectional HDMI to SDI conversion.
The Hyperdeck Shuttle 2 records in ProRes format and stores files as QuickTime files.
The Hyperdeck Shuttle 2 can be mounted to a rig using dual lock fastener straps with a custom mounting plate.
A power regulator should be placed inline when powering the Hyperdeck Shuttle 2 on a Steadicam.
The Hyperdeck Shuttle 2 outputs 10-bit video compared to the Nanoflash's 8-bit output.

The comparison is anecdotal and based on individual user experiences.
No technical specifications are provided for the Hyperdeck Shuttle 2 regarding weight, power draw, or exact recording formats beyond ProRes mention.
Specific use cases and requirements that make one recorder preferable to the other are not systematically evaluated.
