Intel® Solid-State Drives -- Designed for the Job As the storage demands of virtualized and cloud computing continue to escalate, companies and cloud providers seek the most cost-effective approaches to scaling their storage performance. Traditional hard disk drives (HDDs), spinning disks with mechanical parts, are stretched to their limits by virtual machines (VMs) that demand high levels of random input/output (I/O) performance. Solid-State Drives (SSDs), with no moving components, are better equipped to perform the intense I/O required by multiple VMs residing in the same VM datastore. SSDs can do the job more efficiently while providing a simple, high performance, low cost, and low power storage solution. A sample configuration, tested by Intel’s IT Research organization, demonstrates a multi-VM random workload achieving 90- 100K I/Os per second (IOPS) using only 24 300GB Intel® Solid-State Drives 710 Series (Intel® SSDs), a typical cloud workload that would require 450 traditional 15k RPM HDDs to accomplish the same results.
