Unverified热插拔支持并非所有阵列柜标配，选购时确认支持带电换盘，否则RAID降级重建时需关机拆盘，中断工作且延长故障暴露窗口68% similarUnverified接口多、长时间满载使用时机身发热明显，这是DisplayLink芯片方案扩展坞的普遍现象，不影响安全但体感温度较高68% similarUnverifiedNVR长期运行发热是掉盘和死机主因，选购时优先金属外壳、被动散热良好或带风扇机型，避免塑料密闭外壳；安装时留通风空间，多盘位机型尤其需关注散热设计66% similarUnverified散热需求高的用户优先选全镂空+可加装外置风扇接口的支架，实心面板会阻挡底部进风孔反而升温64% similarUnverified面板AP装在86底盒内散热空间小，长期高负载易过热降频，追求峰值性能和高并发（家庭NAS/多设备4K串流）优先选吸顶AP，面板AP更适合信号补盲和低密度场景64% similar
