Description

The Esense C22 (17-CSX222BK) is a streamlined USB 3.0 card reader designed for high-capacity data management. Featuring a dual-slot configuration, it supports SDXC cards up to 2TB and UHS-I speeds reaching 104MB/s. Its lightweight ABS construction and integrated lanyard hole ensure portability without sacrificing performance.

Using the Esense C22 is a seamless plug-and-play experience across Windows and macOS environments. The independent T-Flash slot eliminates the need for adapters, while the USB 3.0 bandwidth significantly reduces wait times compared to legacy USB 2.0 readers. Its slim profile ensures it doesn't block adjacent USB ports on most laptops.

Unlike standard single-slot readers, the C22 offers dedicated paths for both full-sized SD and MicroSD cards. While many budget readers cap at 32GB or 64GB, this model supports the SDXC standard up to 2TB. Compared to integrated laptop card slots, the C22 often provides superior heat dissipation and more consistent UHS-I bus speeds.
