Backwards compatible with SATA I and SATA II; fully compatible with SATA III. Actual data transfer speed is limited by the rating of the attached equipment. RoHS compliant. Use scenarios Desktop PC upgrade or build: add an SSD or HDD to boost OS/app load times and overall storage capacity. Workstation or media server expansion: install additional internal drives for video editing workflows, large media libraries, or backups. IT maintenance: aging internal SATA cables in a server or NAS to ensure reliable, secure connections and prevent drive connection issues.
