Benchmark – Ramnode.com – Atlanta KVM 1 GB

Ramnode.com is still expanding their line of products, and this time they have added KVM plans. And with all Ramnode plans you get some kind of SSD. The plan I tested uses pure SSD RAID setup, but they will also offer SSD-Cached KVM plans soon. With 804 MB/s in disk speed (DD command) this is the second best KVM node ever tested.

Thank you for providing me with this VPS for my test.

Server location: Atlanta, USA
*1024MB SKVM* –$30 / mo
Plan info:
KVM – 1024 MB RAM, 20 GB SSD , 2000 GB BW
Disk info: RAID10 SSD HDD Space
