1DWPD Endurance Rating

The 1 Drive Write Per Day (DWPD) endurance rating indicates the drive’s suitability for read-intensive workloads. It can sustain approximately 960GB of writes per day over a five-year warranty period. This endurance level is optimized for applications with minimal write activity, such as boot drives, log storage, and content delivery networks (CDNs).

Security Features

Self-Encrypting Drive (SED) Technology

The Dell 345-BEJZ SSD incorporates Self-Encrypting Drive (SED) technology, providing hardware-based encryption for data-at-rest. SED ensures that all data written to the drive is automatically encrypted using AES 256-bit encryption, protecting sensitive information from unauthorized access. This feature is critical for compliance with data protection regulations such as GDPR, HIPAA, and PCI-DSS.

Instant Secure Erase

SED-enabled drives support Instant Secure Erase (ISE), allowing administrators to cryptographically erase data by deleting the encryption key. This feature enables rapid decommissioning of drives without the need for lengthy overwrite procedures, reducing downtime and enhancing data sanitization protocols.

Compliance and Certification

The Dell 345-BEJZ SSD meets industry standards for data security and encryption, including FIPS 140-2 and TCG Enterprise specifications. These certifications validate the drive’s suitability for secure enterprise environments, government agencies, and financial institutions.
