256 GB USB 3.2 Gen 2 Type A Drive

This SanDisk Extreme PRO flash drive delivers high-speed portable storage for professionals moving large media files between laptops, desktops and workstations. The USB-A connector ensures broad compatibility with current and legacy ports without adapters.

USB 3.2 Gen 2 interface

The Gen 2 specification is the single factor that determines whether the drive can saturate a 10 Gbps host port; on USB 2.0 or 3.0 hosts the same drive will fall back to the host's maximum throughput.

256 GB capacity with 128-bit AES encryption

Comfortable for raw photo batches, 4K video clips and project archives; the hardware password protection secures sensitive data while the recovery suite helps restore accidentally deleted files. When projects exceed the available space a second drive or higher-capacity model is required.

Soalan tentang produk ini

What does the 1000MB/s read speed mean when I plug this drive into my computer?

The 1000MB/s read figure is the maximum sequential speed the Extreme PRO USB-A can sustain on a USB 3.2 Gen 2 port. Real-world throughput will be lower with small files or older ports.

How does the USB 3.2 Gen 2 interface limit the 900MB/s write speed in practice?

USB 3.2 Gen 2 caps at 10Gbps, so the 900MB/s write rating sits near the bus ceiling. You will only reach it on a native Gen 2 Type-A port with UASP enabled.

What physical space does the metal-bodied SDCZ820-256G-G46 need to fit alongside other ports?

The drive uses a standard USB-A plug with a metal casing and integrated keyring hole. Allow roughly the width of two adjacent Type-A sockets for clearance.
