SSDs Result in Faster, Greener Servers
Because hard disks deliver less than 200 IOs per second (IOPS), many servers spend 99% of their time waiting for disk. Designers try to beat this problem with extra CPUs and RAM, or massive disk arrays. But the easy way to solve the problem is to use flash memory. Unfortunately, most hosters don't know how to do this properly, and spend a lot of money with only limited performance gain. EasyCo, as a primary provider of Flash acceleration technology, can deliver Flash based systems delivering up to a million 4KB IOs per second. More importantly, we can deliver those IOPS at low cost.

Mirroring to Hard Disks
When used in Linux, Raid SuperCharger managed Flash Media can also be mirrored to a hard disk for reduced cost. This reduces the write speed to the linear write speed of the hard disk (which is generally slower than that of Flash media), but can result in significant cost savings, especially for larger surfaces.
