Overview

The Sony MSM4/TQ Memory Stick Micro (M2) Mark2 is a 4GB flash storage card built for Sony's proprietary M2 card slot, found in devices like the Cybershot DSC-TX55 camera and the PlayStation Portable. With read speeds up to 15MB/s, it provides enough throughput to handle Full HD video recording in AVCHD PS mode at 28Mbps — a meaningful capability for compatible Cybershot cameras that support high-definition shooting. The Mark2 designation indicates it meets Sony's updated performance standard for the M2 format, ensuring compatibility with devices that require the newer specification.

At 4GB, the card is best suited for moderate use — enough for a reasonable number of photos or shorter video clips, but users who shoot extensive HD footage will find themselves swapping or offloading files frequently. The Memory Stick Micro form factor is extremely compact, fitting flush into compatible devices without adding bulk. However, it is important to understand that this is a proprietary Sony format; it will not work in standard microSD or SD card slots without an adapter, and Sony has since moved to microSD in its newer products. For owners of legacy Sony devices that require M2 media, this card remains a reliable and purpose-built storage solution.
