Professional reviewers commend the Extreme Portable SSD 1TB for its high sequential read speed, noting it delivers smoother playback when editing video files. They also appreciate its lightweight, bus-powered design and the inclusion of both USB-C and USB-A adapters, which together make it a solid choice for creators on the move.
Everyday users have limited publicly documented feedback, but the available comments emphasize appreciation for the drive's speed, portability, and cross-platform compatibility.
Professional reviewers commend the S70 Blade for its blistering sequential performance, solid endurance, and cost-effective pricing, while noting that sustained write speeds can dip after the cache is filled and that adequate cooling is essential to avoid throttling.
Consumers consistently praise the drive's rapid boot and game load times, quiet operation, and straightforward PS5 installation, but they also report occasional thermal throttling in poorly ventilated cases, higher heat during long writes, and the need for firmware updates on older systems.
