Questions about this item

Will the SDCZ820 run at full speed on my older laptop that only has USB 2.0 ports?

It will work on USB 2.0 ports but speeds drop to the 2.0 limit; the 1000 MB/s read and 900 MB/s write rates need a USB 3.2 Gen 2 port.

How can I verify the drive is delivering the advertised 1000 MB/s read and 900 MB/s write performance after I plug it in?

Run a benchmark tool such as CrystalDiskMark on a USB 3.2 Gen 2 port; sequential read should approach 1000 MB/s and write 900 MB/s.

Does the SDCZ820 package include a USB-C adapter or cable, or do I need to buy one separately for newer laptops?

The drive has a fixed USB-A connector only; no adapter or cable is included, so a separate USB-A to USB-C adapter is required for USB-C-only ports.
