MemoStone US4-1TB portable SSD

The MemoStone US4-1TB is a new external solid-state drive offering 1TB of capacity with 3D NAND memory. It connects via USB 3.1 Gen 2 and includes both Type-C and Type-A connectors for plug-and-play use across devices. Grey aluminium construction keeps weight to 100g.

Upgrade from mechanical drives or USB 2.0 storage

Replacing a spinning hard drive or a USB 2.0 stick with this drive raises sequential reads to 510MBps and writes to 480MBps. The jump is worth it when moving large media libraries, project folders or system images between laptops, desktops and phones that have at least one USB 3.1 Gen 2 port.

Sustained workload behaviour

Under continuous transfer the drive draws 2.15W and is rated for an operating range of -5°C to 60°C with humidity up to 95%. MTBF is specified at 1,000,000 hours, indicating stable performance during extended backups or video offloads without thermal throttling in typical ambient conditions.

商品問答

What are the physical dimensions of the MemoStone US4-1TB so I can check if it fits my bag or port spacing?

The drive measures 85.2 mm long, 20.5 mm wide and 8.0 mm thick, weighing 100 g. Its compact 2-in-1 connector combines USB Type-C and Type-A in one housing.

How do I install the MemoStone US4-1TB, and what common mistake should I avoid?

Plug the dual connector directly into a USB 3.1 Gen 2 port; no driver is required. The mistake is using a USB 2.0 port or hub, which caps speed far below the rated 510 MB/s read and 480 MB/s write.

What maintenance or replacement should I expect for the MemoStone US4-1TB over time?

The 3D NAND flash is rated for 1,000,000 hours MTBF. Keep the drive within -5 °C to 60 °C operating temperature and 5–95 % humidity; no user-serviceable parts exist, so replace the unit if it fails.
