卧槽，昨天我发工单让GVH的VPS移动到Buffalo节点，结果。。

阔空晴云

之前买的那个250G 纯固态硬盘那个，15美元一个季度
IO 确实很屌，最低都是1.1GB/S，高的时候有3GB/S
但是洛杉矶的Colocrossing已经被国人用烂了，于是我发工单转移到Buffalo节点。


结果。。。尼玛。。。Buffalo的节点不是纯固态的，而是所谓的固态缓存的RAID 10 HDD硬盘，IO 只有12MB/S，我为了防止误差，连续测试了两次，两次都10+MB/S！！！！！！！！！！！！！！擦擦擦擦！！！还收了我1美元转移费！！

是啊，他的之前发布的那个15美元一个季度的洛杉矶节点，我测试了十多次，而且是不同时间段，都是1.1GB/S以上，纯固态硬盘应该没错。

什么东西这么叼 难道我眼花了 3GB/s?

这个脚本是 复制1.1GB数据，之前那个洛杉矶节点，都是0.X秒完成，这次这个等好久。。。
我发的截图，是纽约州节点，不是洛杉矶节点，。。别混淆了。。。有关测试结果LET上面的那个促销帖子的回复里面 还有洛杉矶节点测试的截图，不信去看

傻啊，LA的SSD的VPS性能屌爆，250G  一季度你还换走干啥...

主要是网络烂啊，我之前用了GVH的一个试用的Buffalo VPS，虽然延迟大，但是稳定啊。。。没想到转移以后IO这么坑。。。
