Capacity and speed

The MemoStone ZS301-512 is a 512GB portable SSD with a USB 3.2 Gen 2x2 interface delivering up to 1900 MBps read and 1700 MBps write speeds. It uses 3D NAND flash and features RGB lighting on a yellow zinc alloy casing.

Creative pros versus mobile photographers

Suits editors and creators who need fast scratch-disk performance on Windows, Mac or Android devices with USB-C ports. Not for iPhone users or anyone needing larger capacities for full system backups.

20Gbps interface decides fit

The drive requires a USB 3.2 Gen 2x2 port to reach its rated 1900 MBps throughput; on standard USB 3.2 Gen 2 or USB 3.0 ports speeds will be lower. Check your host port before buying.

Questions about this item

How do I install the MemoStone ZS301-512 and what step do people miss?

Connect the USB-C cable to a USB 3.2 Gen 2x2 port for up to 1900 MBps read speed; the step often missed is using a port that actually supports 20Gbps instead of a slower USB-C socket.

What maintenance or replacement will the ZS301-512 need later?

The drive uses 3D NAND with wear-leveling and TRIM, rated for 500TB written and 1,000,000 hours MTBF; no user maintenance is required, and replacement is only needed once the 500TB endurance limit is reached.

What limit appears first during sustained heavy transfers on the ZS301-512?

The zinc-alloy casing dissipates heat, but the operating ceiling is 70°C; prolonged maximum-speed writes can push the controller to that thermal limit, causing throttling before the 1700 MBps write ceiling is sustained.
