SanDisk Ultra Dual Drive Go 128GB Black
Score: 84/100Rankings
The SanDisk Ultra Dual Drive Go 128 GB combines USB-A and USB-C connectors in a swivel design, providing up to 400 MB/s read speeds and lightweight portability. Write speeds are not disclosed and the weight specification varies, and it lacks extensive bundled software. It excels for users who move files between modern mobile devices and legacy computers.
The PNY PRO Elite 256 GB USB-A flash drive delivers industry-leading 400 MB/s read performance and a rugged metal housing with a 64 GB cache for burst writes. Sustained write speeds drop significantly and it lacks a native USB-C connector. Best suited for power users who prioritize fast reads and occasional high-speed writes.

Professional reviewers commend the PNY PRO Elite for its impressive 400 MB/s read capability and solid benchmark score, highlighting the metal construction and 64 GB pSLC cache as strengths. However, they consistently criticize the steep drop in sustained write speeds once the cache is exhausted and the lack of a USB-C interface, positioning the drive as a strong read-focused solution but limited for heavy, continuous write workloads.
Everyday users generally appreciate the rapid read performance and generous 256 GB capacity, noting the drive feels robust and portable. Recurring themes in consumer feedback include frustration with slower sustained writes after the cache fills and occasional warmth during prolonged transfers, while the missing USB-C option is also mentioned as a drawback.
Professional reviewers describe the Ultra Dual Drive Go as a well-designed, ultra-light flash drive that combines a sleek swivel form factor with fast 400 MB/s read performance. They note its large 128 GB capacity removes the need for multiple smaller drives and applaud its broad compatibility across Android, iOS, Windows, and macOS platforms. The dual USB-A/USB-C interface is repeatedly highlighted as a key advantage for mixed-device environments.
Everyday users, though not quoted directly, consistently mention the drive's portability and the convenience of having both USB-A and USB-C connectors in one tiny device. The keyring hole and swivel protection receive positive nods, while the lack of published write-speed numbers and occasional confusion over the exact weight are minor points of uncertainty.
