2 days ago, I bought a storage VPS from GreenValueHost. Although the VPS was glitched, their owner Jonathan was actively willing to solve the problem. Finally the 8T ram glitch was fixed. Here I'm going to show you the simple I/O, Network & Over selling test of the storage VPS I bought.
the VPS Specification:
OpenVZ Virtualization
290GB SSD Accelerated RAID-10 Disk Space
30TB Premium Bandwidth @ 1Gbps Port
4048MB Guaranteed RAM
6144MB Burstable RAM
2 IPv4
$5.00/month OR $40.00/year - NO CONTRACTS and NO BS -

The following over selling test is generated by a piece of C code to test what much RAM the VPS can occupy.
Allocated: 4347M Allocated: 4348M Allocated: 4349M Allocated: 4350M Allocated: 4351M Segmentation fault root@VMCAT-GVH:~#
The node is using E3-1240 v3 which allows the maximum RAM of 32G. As you can see, 4351M seems to be the usable RAM matching the VPS specification: "4048MB Guaranteed RAM". After that, the program breaks.
Conclusion:
Although, GreenValueHost's domain was registered in 2012, because of the affordable price of their VPSes, it's worth trying. If the VPS is allowed to use 4G Ram of 32G in E3 node, it's not bad for its price.
