Capacity and audience

The MemoStone ZS301 provides 1TB of 3D NAND storage in a compact, battery-inspired enclosure with a yellow finish and RGB lighting. It connects via USB 3.2 Gen 2x2 Type-C for plug-and-play use with Windows, Mac and Android devices, targeting users who need fast portable capacity for large media files and backups.

Host-side checks

Verify that your computer offers a USB 3.2 Gen 2x2 Type-C port able to deliver 20Gbps bandwidth; slower ports will reduce the 1900 MBps read and 1700 MBps write peaks. The drive is not recommended for iPhone products, so confirm your intended host appears in the supported device list before ordering.

Sustained-load behaviour

A zinc-alloy casing dissipates heat during extended transfers, helping the controller maintain performance within the 0°C to 70°C operating range. Power management, TRIM, SMART, NCQ and wear-levelling features protect the NAND over the 1000 TBW endurance rating, while idle draw sits at 0.5W and active draw at 2.6W.

Questions about this item

Does the ZS301-1TB come with a cable or do I need to buy one separately?

The drive uses a Type-C connector with plug-and-play support; the built-in loop keeps the cable secure, but the supplier data does not confirm whether a cable is included in the box.

Should I choose the 512GB, 1TB or 2TB version of the ZS301?

All three capacities share the same 20Gbps interface and up to 1900 MBps read speed; pick 1TB for a balance of space and cost, 512GB for lighter needs, or 2TB for maximum capacity.

What does the 1900 MBps read figure mean when I plug the drive into my laptop?

It is the maximum sequential read speed over USB 3.2 Gen 2x2; real-world throughput depends on the host port, cable quality, file sizes and thermal conditions, and may be lower on MacBook.
