Kingston Exodia M
Score: 59/100Rankings

SanDisk's 128 GB Ultra Dual Drive provides fast up to 150 MB/s read speeds and dual micro-USB/USB-3.0 connectors for seamless Android-to-PC transfers. The slower write speed and need for OTG-compatible devices are trade-offs. Ideal for Android photographers needing quick off-load of media.

The Kingston Exodia M offers a compact, lightweight design with a protective cap and solid 100 MB/s read performance. Its plastic build and unspecified write speeds limit its appeal for power users. Best suited for students and casual users needing affordable portable storage.

Professional outlets such as Adorama and B&H focus on the drive's fast 150 MB/s read performance and its dual-connector OTG design, noting that it fills a niche for legacy micro-USB Android devices while offering reliable cross-platform compatibility. However, the scarcity of in-depth reviews leaves some uncertainty about durability and real-world write speeds.
Everyday users generally praise the convenience of moving large media files between Android phones and computers without extra adapters, and they value the Memory Zone app for automated backups. Recurring concerns revolve around slower write speeds, the necessity of an OTG-capable device, and the lack of clear durability information.

“Super-fast transfers (up to 150 MB/s, faster than USB 2.0 for movies/photos).”

“Frees Android storage via OTG and app.”




Professional reviewers stress the Exodia's reliable USB 3.2 Gen 1 performance, practical cap and keyring design, and the reassurance of a five-year warranty.
Everyday users mention that the drive meets basic storage needs and appreciates its lightweight feel and portability, but note that speeds can be inconsistent and the cap may be lost if not attached.
