KingSpec Z5-4TB portable SSD

The KingSpec Z5-4TB is a new external solid-state drive offering 4TB of 3D TLC storage in a black zinc-alloy case with RGB lighting. It connects via a USB 3.2 Gen 2x2 Type-C interface that also supports Thunderbolt 3, delivering up to 2100 MBps sequential read and 1850 MBps sequential write speeds for photographers, content creators and gamers who move large files.

Suits USB 3.2 Gen 2x2 hosts.

This drive suits users whose computers provide a USB 3.2 Gen 2x2 or Thunderbolt 3 port to utilise the 20Gbps bandwidth. Buyers limited to older USB standards will see reduced transfer rates, and the supplier notes the product is not recommended for iPhone-related devices. No driver installation is required for plug-and-play operation on supported platforms.

Deciding spec: USB 3.2 Gen 2x2 with Thunderbolt 3

The single specification that decides fit is the USB 3.2 Gen 2x2 interface with Thunderbolt 3 support, which enables the rated 2100 MBps read and 1850 MBps write performance. Without a host port capable of 20Gbps throughput the drive will operate at lower speeds, so verify your system provides this exact interface before purchase.
