[ REMOVABLE MEDIA // USB FLASH DRIVE ]
Extreme Go 256 GB (SDCZ810-256G-G46)
A model- and capacity-specific record for the removable USB flash-drive device, not a general promise for every revision sold under the same family name. Verify the complete SKU and capacity on the label.
PRODUCT: SanDisk Extreme Go 256 GB (SDCZ810-256G-G46). A physical USB connector fit does not prove that a host supports the drive's capacity, filesystem, power needs, or advertised bus mode.
Model, interface and compatibility
| Manufacturer model / SKU | SanDisk Extreme Go 256 GB (SDCZ810-256G-G46) |
|---|---|
| Nominal capacity | 256 GB; formatted usable space is lower and varies by filesystem and host. |
| USB generation / connector | USB 3.2 Gen 1; USB Type-A. |
| Host compatibility | USB Type-A host. SanDisk SecureAccess encryption software is host-software-based (not drive hardware encryption); operating-system requirements vary by current software release. Backward-compatible with USB 3.1 Gen 1, USB 3.0, and USB 2.0 hosts. |
| Dimensions | 60.3 × 18 × 7.4 mm; dimensions are manufacturer-stated for the named model/family. |
| Manufacturer speed claim | SanDisk advertises up to 400 MB/s read and up to 240 MB/s write for the 256 GB product; these are maxima, not guaranteed sustained rates. |
| Encryption | Optional SecureAccess software is described as 128-bit AES encryption of a private vault; software support and recovery depend on the host. This does not encrypt all files automatically. |
Wear, encryption and preservation caveats
Flash memory wears with writes, and controller, NAND, firmware, age, temperature, and storage conditions affect retention and failure risk. No shelf-life or archival-life guarantee is inferred from this product record. The manufacturer documentation cited here does not establish a guaranteed service life or archival retention period.
- Optional SecureAccess software is described as 128-bit AES encryption of a private vault; software support and recovery depend on the host. This does not encrypt all files automatically. Do not treat an unencrypted USB stick as a secure transport or a sole copy of important data.
- Write endurance, wear-leveling behavior, and power-loss recovery are not quantified here unless explicitly stated by the manufacturer for this exact SKU; do not infer them from a speed or warranty claim.
- Use safe removal where required by the host's write cache, keep the device dry and protected from impact, and do not remove it during activity.
- For preservation, keep at least two independent additional copies, record checksums, periodically read/verify the data, and migrate it to supported media. Flash storage is not a substitute for a preservation plan.
