Hardware-based AES-256 encryption, built into the drive controller, is meaningfully more secure and often faster than software-based encryption, worth verifying and disclosing which encryption type a product actually uses rather than treating 'encrypted' as one undifferentiated claim.
Some encrypted drives offer no recovery path for a forgotten password, resulting in permanent, unrecoverable data loss, a real risk worth disclosing upfront rather than discovering after the fact.
4 Criteria to Look For Before Buying a Encrypted Portable SSD
Key buying criteria so you get the right fit the first time.
Hardware encryption is meaningfully more secure than software encryption
Verify which type a specific drive actually uses, don't assume 'encrypted' marketing means the more secure hardware-level implementation built into the controller.
A forgotten password can mean permanent, unrecoverable data loss
Some encrypted drives offer no recovery path at all, understand this risk upfront before you're locked out of important files with no way back in.
FIPS certification matters for compliance-driven buyers
Verify actual FIPS 140-2/140-3 certification status rather than accepting generic 'encrypted' marketing claims if you have formal compliance requirements.
Encryption overhead can measurably reduce real-world speed
Encryption/decryption processing can reduce throughput compared to the same drive's unencrypted performance, don't assume the rated speed applies identically with encryption enabled.
