The X7K8W is not compatible with 2.5-inch SFF chassis drive bays, providing mechanical retention and vibration damping in LFF enclosures.
How to identify a genuine unit
Genuine Dell drive caddies carry stamped DP/N 0X7K8W markings on the metal frame, along with release handle latch markings and light pipe routing. The front bezel of the X7K8W features clear plastic light pipes that channel status and activity LEDs from the drive backplane.
