BitCable – 4美元 KVM 256M 12G 150G

BitCable最近正在推广他家基于KVM技术的VPS，在周年之际推出了终身5折的优惠码happybirthday!，凭借此优惠码，256M内存，12G硬盘，150G流量的KVM仅需4美元/月（原价8美元）。前段时间BuyVM家的KVM可以说让大家过足了KVM的瘾头。这个BitCable的低价KVM相信也不会让大家失望。

本款VPS已火速全线被抢光，据称下周将上货，但不知道优惠码还能不能用~

BitCable – 4美元 KVM 256M 12G 150G

• 256MB memory
• 12GB storage
• 150GB/month data transfer on 1Gbps
• KVM/SolusVM
• 测试ip：209.9.238.4
• 直接购买

当然，这款KVM的价格虽然厚道，性能也不错(UnixBench跑分测试)，但是缺点很明显，他家机房的位置位于Latisys的阿什本（Ashaburn）机房（美国东岸），国内连接速度一般。
