BitRaser Drive Eraser vs Lethe

BitRaser Drive Eraser is software for permanently erasing data from computers and storage media, including hard drives, SSDs, PCs, laptops, Macs, Chromebooks, and servers. It supports up to 26 global erasure methods and five custom standards, including NIST Clear and Purge and IEEE 2883:2022. Supported media include SATA, PATA, SSD, NVMe, M.2, SAS, SCSI, IDE, SED, USB, and Fusion drives. Erasure results can be documented with tamper-proof certificates and reports saved as PDF, CSV, or XML. Deployment choices include bootable USB, PXE, an offline variant, and remote wiping of Windows endpoints through an MSI package. The Cloud console manages users and licenses and stores reports and certificates; private cloud is available at additional cost. Licenses cost $99 as a one-time purchase, taxes extra, with volume-based pricing. Each license covers one drive and is consumed when erasure begins; unused licenses do not expire. A free license is offered for business use.

Lethe is a free, open-source command-line utility for wiping drives on Linux, macOS and Windows. It overwrites existing data with randomly generated data or a static pattern, then can read data back to check whether write commands succeeded. The project says it should work with HDDs, flash drives and SSDs, but warns that its current approach cannot reliably erase all SSD data because of wear leveling and compression.

Lethe requires root or administrator access to operate on real drives. It uses a fast cryptographic random generator and lets users override the operating system's recommended block size. It can track and automatically skip bad blocks and other localized errors, though that feature is experimental. Available binaries cover Windows x86-64, Intel macOS, experimental Apple macOS and Linux x86-64; installation from Rust sources is also documented. The project says initial active development is complete, though occasional changes may still be made. Lethe is licensed under Apache License 2.0.
