JetFlash 920 256 GB (TS256GJF920)
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: Transcend JetFlash 920 256 GB (TS256GJF920). 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 | Transcend JetFlash 920 256 GB (TS256GJF920) |
|---|---|
| Nominal capacity | 256 GB; formatted usable space is lower and varies by filesystem and host. |
| USB generation / connector | USB 3.2 Gen 1 (USB 5Gbps; USB 3.1 Gen 1 naming also used); USB Type-A. |
| Host compatibility | Transcend specifies Windows and macOS compatibility for the JetFlash 920 family. Requires a USB Type-A host; bundled/recovery software has separate OS requirements. Compatible with earlier USB hosts at their supported rate. |
| Dimensions | 62 × 20 × 7.8 mm; dimensions are manufacturer-stated for the named model/family. |
| Manufacturer speed claim | Up to 420 MB/s read and 400 MB/s write are manufacturer claims for the JetFlash 920 family; actual performance varies with host, workload, and capacity. |
| Encryption | No hardware encryption claim appears in the cited JetFlash 920 product/support material. |
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.
- No hardware encryption claim appears in the cited JetFlash 920 product/support material. 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.

Any stated maximum speed is a manufacturer claim, not a guaranteed sustained rate; real results depend on the complete host path, file sizes, filesystem, and device revision.
