Counterfeit Storage: Detect Fake SSDs & USB Drives
11 Dec, 2025
Summary
- Counterfeit SSDs and USB drives are sold as bargains on online marketplaces.
- F3 tools like f3probe reliably detect fake storage by checking real capacity.
- NAS drives require CMR technology; SMR drives are unsuitable for RAID.
Beware of counterfeit flash storage devices appearing as bargain deals on online platforms. These fraudulent products, including SSDs and USB drives, often disguise themselves with fake specifications, deceiving operating systems about their true storage size and capabilities. External drives can employ controllers that simulate larger capacities, while actual data storage is significantly less.
Fortunately, Linux tools like F3 (Fight Flash Fraud) offer a robust solution. The f3probe utility can non-destructively verify a drive's actual capacity and performance, unaffected by manipulated controller chips. For users concerned about data integrity, f3write and f3read offer a more thorough, file-system-level check.
In the realm of Network Attached Storage (NAS), drive technology is paramount. Only Conventional Magnetic Recording (CMR) drives are generally suitable for RAID setups and ZFS file systems, as Shingled Magnetic Recording (SMR) drives, despite being marketed as NAS drives, introduce errors and delays due to their data recording method.
