RAID 6 with 5400 RPM hard drives ensure data security

RAID 6 with 5400 RPM hard drives is chosen mainly for reliability and data protection rather than speed. The dual-parity design allows the array to withstand the failure of two drives without data loss, which is important when using large drives that can take a long time to rebuild. Slower 5400 RPM disks run cooler, use less power, and experience less mechanical stress, making them a good fit for systems that stay online all the time. Although performance is lower, especially for writes, this setup works well for backups, file storage, and long-term data retention where stability and data safety matter most.
