The drive uses 3D TLC NAND flash, is rated for 60 TB total bytes written and 1,500,000 hours MTBF, and supports TRIM, S.M.A.R.T. monitoring, and hardware ECC error correction. The 2.5-inch 7 mm form factor with SATA III 6 Gb/s interface (backward-compatible with SATA II) fits any standard laptop or desktop.

Yes. Every ColdGuardian arrives pre-loaded with a security-hardened operating environment and XColdPro BootVault, sealed with tamper-evident packaging and authenticated via Certificate of Authenticity. You plug it in, boot, and you are immediately in a fully air-gapped cold-storage deployment — no setup, no downloads, no exposure.

A ColdGuardian eliminates setup risk. The operating system is stripped to essentials, hardened against common attack surfaces, and validated before shipping. You get a purpose-built air-gapped environment without needing to source compatible hardware, configure a clean OS, or verify your supply chain yourself.
