带雷电3端口的NAS，QNAP TS-453BT3拆解
这次为QNAP TS-453BT3搭载的是来自Western Digital的四块RED 2T硬盘。该硬盘适合家庭和中小型企业使用，采用了西数独一无二的NASware 3.0技术，提高了兼容性、集成度、可升级能力和可靠性，进而改进了NAS系统的存储性能https://image.koolshare.cn/attachment/forum/201909/18/163011hj2lienx0ldx0xlr.jpg
▲将四块RED 2T硬盘装上QNAP TS-453BT3，由于NAS系统要一直保持运行，因此可靠的硬盘至关重要。而WD RED硬盘自带的3D Active Balance Plus技术能够确保您的数据免受NAS或RAID环境中的剧烈振动和噪声影响。这项增强型双面平衡控制技术可以确保硬盘性能持续稳定
