Portable SSD for mobile workflows

The KingSpec US5-512 is a 512GB external SSD built around a USB 3.2 Type-C interface. It delivers sequential reads up to 2000 MBps and writes up to 1800 MBps for fast file transfers. The aluminium alloy shell measures 38.18mm by 71.16mm by 11mm and weighs 20g. It operates from 0°C to 70°C with an MTBF of 1000000 hours.

Suited for creators and general users

Video editors who record Apple ProRes directly from iPhone 15 Pro or Pro Max will benefit from the sustained write performance. The drive works with laptops, tablets and phones across platforms without drivers. Buyers who need more than 512GB of capacity should look at larger models. Users whose devices only support slower USB standards will not reach the advertised speeds.

USB 3.2 Gen 2x2 speed ceiling

The single specification that decides fit is the USB 3.2 Gen 2x2 interface enabling up to 2000 MBps reads and 1800 MBps writes. Apple devices are limited to 10Gb/s by the host, so actual throughput will be lower on those platforms. Verify that your host port supports the full 20Gb/s bandwidth to utilise the drive’s maximum performance.

Questions about this item

How hot does the US5-512 get when transferring large files continuously?

The aluminium alloy shell provides heat dissipation and the drive is rated for 0 °C to 70 °C operating temperature, so it stays within safe limits during sustained use.

Which cable or port must my device already have to reach the 2000 MB/s read speed?

You need a USB 3.2 Gen 2×2 Type-C port and cable; Apple devices are limited to 10 Gb/s over the same connection.

Will the US5-512 work with an older laptop that only has USB 3.0 Type-A ports?

Yes, it is backward compatible with USB 3.0 and USB 2.0, though speeds will drop to the older port's maximum.
