MemoStone US4-256 256GB Portable SSD
The MemoStone US4-256 is a 256GB external solid-state drive built around 3D NAND flash memory. It connects via USB 3.1 Gen2 and includes both a USB Type-C and a USB Type-A connector in a single housing. The drive weighs 100g and measures 85.2mm by 20.5mm by 8.0mm. It is suited for users who need fast, portable storage across devices with different USB ports.
For users needing dual-connector flexibility
This drive suits anyone who moves files between newer Type-C laptops and older Type-A desktops without carrying adapters. Sequential reads reach up to 540 MBps and writes up to 480 MBps, which handles large media transfers quickly. Buyers who need hardware encryption, ruggedised IP-rated casings, or capacities above 256GB should look at other models. The operating range of -5°C to 60°C covers typical office and travel use.
USB 3.1 Gen2 interface with 540 MBps peak read
The single specification that decides fit is the USB 3.1 Gen2 interface rated for up to 540 MBps sequential read and 480 MBps sequential write. Your host port must support USB 3.1 Gen2 (10 Gbps) to reach these speeds; older USB 3.0 or 2.0 ports will limit throughput. The 2.15W active power draw is supplied entirely by the bus, so no external adapter is required.

How fast will the 540 MB/s read speed actually be when I copy files to my laptop?
You will see up to 540 MB/s sequential read and 480 MB/s write on a USB 3.1 Gen 2 port; speeds drop on older USB ports.
What does the USB 3.1 Gen 2 interface mean for real-world transfer limits?
The USB 3.1 Gen 2 connection caps at 10 Gbps, so the drive's 540 MB/s read and 480 MB/s write are the practical ceiling.
Will the 85.2 mm by 20.5 mm dual connector fit beside other ports on my ultrabook?
The drive measures 85.2 mm long, 20.5 mm wide and 8.0 mm thick; allow a little extra clearance for the flip-out Type-A plug.
