Yottamaster 512GB External SSD - Portable 460MB/s Fast Storage

In this review of the Yottamaster 512GB External SSD the bottom line is simple: this compact drive is aimed at photographers, videographers and power users who need fast, reliable portable storage without bulk. The single biggest reason to buy is its sustained read speed of up to 460MB/s, which makes moving large files and capturing 4K ProRes footage from compatible phones practical. The drive is palm-sized, includes a strap and a 2-in-1 cable, so it is ready for on-the-go workflows right out of the box.

Key Features

• High-speed transfer: Read speeds up to 460MB/s let users move a 1GB file in roughly 2 seconds, speeding up offloading and backups.
• Compact portability: The palm-sized design and 135g weight make it easy to carry daily and hang from a bag with the included strap to avoid loss.
• 4K ProRes support: Enables real-time recording and saving of 4K ProRes videos on iPhone 17/16 Pro and Pro Max without switching storage mid-session.
• 2-in-1 cable included: The bundled cable works with both USB-C and USB-A hosts, so it connects to smartphones, tablets, laptops and older PCs without extra adapters.
• Multiple capacities: Available in 512GB, 1TB and 2TB options to suit everyday file storage or large 4K video projects.

Who It's For

The drive is best for mobile creators who record high-resolution video and need a compact external SSD that supports 4K ProRes recording from compatible iPhones and moves large files quickly to a laptop. It also suits travelers and business users who want a reliable, lightweight backup drive that can be carried on a keyring or clipped to a bag.

It is less compelling for users who only need occasional small-file backups or who require built-in hardware encryption and enterprise features not described for this model. Desktop users who value maximum sustained write speeds above consumer NVMe external performance may want a higher-end alternative.
