User Manual
FAQ
What is the actual storage capacity available to the user?
The drive provides 128GB of raw storage capacity, though the usable space may be slightly less due to file system overhead and manufacturer formatting. This is sufficient for approximately 32,000 high-resolution photos, 30 hours of HD video, or thousands of documents, depending on file sizes and compression.
How fast is the USB 3.0 transfer speed on this flash drive?
The USB 3.0 interface supports theoretical transfer speeds up to 5 Gbps (625 MB/s), though real-world performance depends on file types, system configuration, and drive health. Expect significantly faster transfers compared to USB 2.0 drives, especially with large files like videos or disk images.
Is the retractable mechanism durable over time?
Yes, the retractable design is engineered for repeated use with a smooth sliding action that protects the USB connector. The metal housing and internal components are tested for longevity, reducing wear compared to traditional cap-based designs that can loosen or get lost.
What colors are available for the JetFlash 790?
This model features a two-tone black and blue color scheme, combining a dark primary body with blue accent details. The metal finish ensures the colors remain vibrant and resistant to fading under normal use conditions.
Can this drive be used with USB 2.0 ports?
Yes, the JetFlash 790 is fully backward compatible with USB 2.0 ports, though transfer speeds will be limited to USB 2.0 rates (up to 480 Mbps). It automatically negotiates the best available speed with the host device without requiring drivers for most operating systems.
What are the dimensions and weight for portability?
The drive measures 2.50 inches long, 0.83 inches wide, and 0.42 inches high (63.60 x 21.20 x 10.60 mm), with a weight of 0.353 ounces (10 grams). This compact and lightweight profile makes it easy to carry in pockets, attach to keychains, or store in small compartments without adding noticeable bulk.
