Deployed with SAS disks for primary storage of a cloud application, such as webmail or a photo sharing site, a small 100-node RING can deliver hundreds of thousands of objects per second, with a predictable latency below 40 milliseconds at a cost of less than $1/GB. When deployed with large SATA disks for long term storage such as cloud backup, Scality RING’s total cost of operation is only a few pennies per GB per month.

Although Scality RING is hardware agnostic and the costs depend on the hardware selected, they tend to go down proportionally as you scale up the storage usage of your system. The following diagram shows the dollar costs for Scality RING per GB of storage per month of total usable capacity in Terabytes. When using 100 GB of storage per month, data centre power and cooling costs are approximately three cents per GB. If you use 15 TB of storage per month, these costs go down to less than a penny per GB.
