2.5-inch SATA to USB: use the drive-power scope

USB3S2SAT3CB is documented for 2.5-inch SATA drives and expressly excludes 3.5-inch hard drives. Its matching SATA shape does not supply an arbitrary drive’s power.

Applies to: Kingston A400 SA400S37/480G 2.5-inch SATA, USB3S2SAT3CB USB-A bridge, 13-inch Retina Early-2015 MacBook Pro native USB3 port and factory-era OS X Yosemite; documentary interface matching, not a tested combination.

Functional path diagram. Arrows show the stated role and direction; they do not report an observed connection.

What the path requires

  • Confirm exact drive form and SATA interface; an M.2 drive is not this direct connection.
  • Use an exact host with documented USB-A data/power and supported OS; Mac OS X10.8+ is the adapter's historical UASP scope.
  • Protect existing data; the guide does not require initialization or formatting to identify an attached device.

One whole path with an older host

The Early-2015 MacBook Pro provides native USB3 Type-A ports. Factory-era OS X Yosemite is within the adapter's stated Mac OS X 10.8-or-later UASP context. Historical interface support does not establish current OS security support.

Your next useful observation

Confirm the exact Mac model/OS, native USB3 port, drive SKU and adapter before copying; preserve existing data.

Keep these limits

  • Historical OS compatibility is not current security support.
  • No benchmark or drive-health test.
