This is actually a set of devices. NitroPad is a preconfigured refurbished x230 laptop, with replaced firmware and deactivated IntelME, as well as removed WiFi module on request. With it comes a companion device, Nitrokey Pro or Nitrokey Storage, which takes part in the boot verification process. Together they form a secure workstation. Closest to your description is Nitrokey Storage, which in feature terms is a Nitrokey Pro, but extended with an encrypted storage on an SD card. Disclaimer: I work with Nitrokey.
