Best Solutions for Your Computer

Important Data Tips
- HDD is better for long-term storage - a fresh, lightly used SSD will hold data without power for many years, but a heavily worn one (after exhausting its write cycles) can lose it much sooner. The JEDEC standard only requires a consumer SSD to retain data for a minimum of one year without power AT THE END of its life - the "data fades after a year" myth applies only to worn-out drives
- Important data always in 3 copies - on different media and in different locations
- Use SSD for daily work and HDD for backup storage!
