Capacity, interface and compatibility
| Manufacturer model | LCXEXPR001T-RNENG; CFexpress 4.0 Type B, Professional GOLD |
|---|---|
| Nominal capacity | 1 TB. Usable space varies with formatting and system-reserved capacity. |
| Interface | PCIe 4.0 x2 / CFexpress 4.0 Type B. |
| Performance | Lexar rates this 1 TB GOLD 4.0 product up to 3,600 MB/s read, up to 3,300 MB/s write, and 3,000 MB/s sustained write. Peak speed requires a compatible CFexpress 4.0 reader/host. |
| Host compatibility | A device that supports CFexpress Type B and the 1 TB capacity. A Type B connector alone does not guarantee CFexpress 4.0 speeds; consult the camera/reader compatibility list and firmware notes. |
| Write protection | No physical card-level write-protect switch is specified for this model; use host controls and verified backups. |
| Model-specific note | This is the 4.0 1 TB GOLD model, not the separate GOLD CFexpress 2.0 128 GB record. Lexar notes card transfer speeds vary with reader and host capability. |
Handling and preservation
No finite shelf-life or archival-life guarantee is claimed here. Keep the card clean, dry, labeled, and in its protective case; avoid touching contacts and never remove it during a write. After use, verify files and maintain multiple checksummed copies on independent media. Before a migration or recovery, record the exact card SKU, camera/reader, firmware, filesystem, and host.
