256 GB portable SSD for fast external storage

The MemoStone ZS301-256 provides 256 GB of 3D NAND flash in a compact yellow enclosure. It connects via USB 3.2 Gen 2x2 Type-C and delivers up to 1900 MB/s read and 1700 MB/s write speeds. The drive suits users who need quick file transfers and backups across Windows, Mac and Android devices.

Zinc alloy body with RGB light and cable loop

A zinc alloy casing acts as a heatsink to maintain stable performance during heavy workloads. The battery-inspired shape includes a built-in loop that secures the cable for travel. An RGB top light adds visual flair while the drive draws 2.6 W active and 0.5 W idle power.

USB 3.2 Gen 2x2 limits and compatibility notes

The 20 Gbps interface requires a host port that supports USB 3.2 Gen 2x2 to reach rated speeds; performance drops on slower ports or MacBook connections. The drive is not recommended for iPhone-related products. Endurance is rated at 250 TBW with a 1,000,000-hour MTBF across 0 °C to 70 °C operating temperatures.
