Professional reviewers consistently praise the S70 Blade for its industry-leading sequential speeds, slim form factor, and solid value, while noting copy-performance gaps and thermal throttling as the only notable drawbacks.
Everyday users report dramatically faster boot and load times, especially in gaming and content-creation tasks, but some experience thermal throttling during prolonged heavy loads.
Professional reviewers commend the Kingston Dual Portable SSD for its clever dual-connector design, near-spec USB 3.2 Gen 2 speeds, and solid metal construction, calling it a convenient, high-performance alternative to traditional flash drives. However, they note practical drawbacks such as port blocking, fragile caps, lack of environmental sealing, and thermal throttling under sustained load.
Everyday users appreciate the drive's universal compatibility, lightning-fast transfers, and pocket-friendly size, often highlighting how it eliminates the need for cables. Common complaints revolve around the device's tendency to block neighboring ports, the easy loss of protective caps, heat buildup with speed throttling, and the absence of a tether or keychain loop.
“Dramatically faster boot and load times compared to my old SSD”
“Temperatures climb into the 40s°C under sustained load, causing throttling”
“Great performance for the price, no RGB needed”
