The transfer rate for XS2000 Portable SSD is contingent on multiple factors. The interface used to connect the drive to the computer may also limit transfer speeds. The interface needed for optimal performance is USB 3.2 Gen 2x2 (20Gbs)

Make sure the following apply:
  • Please use the cable that was bundled with the XS2000. Other cables could be of low quality or spec'd for low data transfer rates. If you decide to use another cable, please check the cable specifications.
  • The host machine must have an available Type-C USB 3.2 Gen 2x2 port.
  • The host machine should have the latest updates (e.g., BIOS, Chipset drivers, USB drivers).

Yes. The XS2000 Portable drive is Mac compatible. However, the drive performance will not be as advertised because the USB protocol on Mac is not USB 3.2 Gen 2x2.

FAQ: KSD-002201-001.02


This is common for flash storage, whether internal SSD, Flash Card, or external USB storage, and is due in part to a variance in how flash memory vs spinning platter hard drive manufacturers calculate megabyte. Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, whereas the binary calculation for flash-based storage is 1,024KBs.

Example: For a 1TB flash-based storage device, Windows will calculate it as having a capacity of 931.32GB. (1,000,000,000,000÷1,024÷1,024÷1,024=931.32GB).

Furthermore, Kingston reserves some of the listed capacity for formatting (e.g., File Allocation Table) and other functions such as firmware and/or controller-specific information, and thus some of the listed capacity is not available for data storage.
