Portable 512GB SSD with USB 3.2 Gen 2x2 Type-C

The KingSpec Z5-512 is a portable solid-state drive offering 512GB of 3D TLC storage. It connects via USB 3.2 Gen 2x2 Type-C for up to 2100 MBps sequential read and 1850 MBps write speeds. A zinc alloy body aids cooling while RGB lighting adds visual flair. Plug-and-play operation requires no drivers.

Creators needing fast external storage

Photographers, videographers and gamers who move large files between devices will benefit from the 20Gbps interface and compact 104.70mm by 40.00mm form factor. Buyers whose devices lack USB 3.2 Gen 2x2 Type-C ports will not reach the advertised throughput and should consider drives matching their available ports.

Interface speed decides suitability

The drive delivers its rated 2100 MBps read and 1850 MBps write only over a USB 3.2 Gen 2x2 Type-C connection running at 20Gbps. On slower ports or MacBook hosts the transfer rate drops proportionally, so verify your host port before purchase.

Questions about this item

Is the 512GB capacity the only option in the Z5 series?

The Z5 series also offers larger capacities, with up to 4TB available for users who need more space for games, images or 4K video files.

What does the 2100 MB/s sequential read figure mean when the drive is connected to a real machine?

The 2100 MB/s read and 1850 MB/s write speeds are laboratory maximums; actual transfer rates depend on the host device and its USB implementation, and may be lower on some laptops.

What does the USB 3.2 Gen 2x2 Type-C interface cap in practice?

The interface supports up to 20Gbps bandwidth, but real-world throughput is limited by the host controller, cable quality and thermal conditions during sustained workloads.
