前几天实在没忍住就剁了一台LV RYZEN KVM 1GB+512GB块存储。小鸡3.5刀，块存储2.5刀，相当于月付6刀。
买之前已经做好心理准备了，本以为是上了个拖拉机，没想到用了几天发现各方面还不错，有点出乎意料。。所以也就有动力水一下这篇文章了。。
简单测评
CPU和内存：
硬盘20GSSD，那个512G是额外挂载的块存储，后面我会写到如何挂载：

总结一下，CPU很给力，SSD系统盘性能很爆炸，块存储的性能也很OK，这是我用过这么多大盘鸡中硬盘性能数一数二的了。
如何购买
戳这里：https://my.frantech.ca/aff.php?aff=3861&gid=37
本文测评机的配置是3.5刀款：
1H1G
20GSSD
Unmetered Bandwidth
如果需要块存储挂载请购买LasVegas区域，只有这个区域的机器可以挂载：
注意事项：
1.这家对新账号较严格，注册的时候不要使用VPN或者代理，很大概率被判定为欺诈订单。
2.注册时的信息和付款时的信息需要一致，尤其是使用PayPal付款的时候要保证姓名和邮件一致。
如何挂载块存储
首先登录VPS控制面板，找到StorageVolumes，按下图设置：
在VPS内检查硬盘是否已经附加进来：
fdisk -l可以看到一块没有分区的/dev/sda：
接下来创建分区：
fdisk /dev/sda按照下图的流程走即可：
检查分区是否正常：
然后制作文件系统，这里我选择使用xfs：
apt -y update
apt -y install xfsprogs
mkfs.xfs /dev/sda1如果一切正常，会有类似如图的回显：
最后创建挂载目录并挂载：
mkdir -p /storage
mount /dev/sda1 /storage开机自动挂载，编辑fstab：
nano /etc/fstab文件的末尾加入：
/dev/sda1 /storage xfs defaults 0 0
