Using tamper-evident bags when transporting physical storage devices is the best practice for maintaining the chain of custody. This is because they provide a clear indication if any unauthorized access has occurred during transit. Using gloves only prevents fingerprints and antistatic bags are more for protecting components from ESD, not for security purposes. Labeling alone, while important, does not prevent tampering. Correct handling goes beyond simple labeling; it involves securing the evidence to protect it from physical tampering, which is achieved with the use of tamper-evident bags.
