『测评』RAKsmart–美国CN2 SSD机型综合测评 主机测评 第1张

『VPS』RAKsmart – 1核/512M内存/20G HDD/不限流量/KVM/圣何塞CN2/9.9元/月

RAKsmart上个月刚有一波优惠活动,前几天又发来邮件,大概意思是说其机房除了现有的电信CN2线路外,又成功接入了中国移动和中国联通两大运营商的直连线路,完成中美精品网的部署。

下面测评的机型为Cn2 SSD L512,配置为

  • vCPU:1
  • 内存:512MB
  • 硬盘:20GB SSD
  • 流量:不限
  • IP:1IPv4
  • 架构:KVM
  • 价格:50元/月
