SAN Storage Buying Guide


SAN Storage Buying Guide provides comparisons of the feature sets and detailed performance of major SAN storage systems in the market today.  In addition, we provide a detailed discussion of SAN storage systems features so you can know what to look for in systems your are evaluating.



  • Advanced Feature Descriptions

    We explain advanced storage features and their significance.

  • Product Feature Comparisons

    We compare features and functionality across products.

  • Block IO Performance Focused

    We discuss product performance and rank storage systems.

  • One Hour Phone Consultation

    We offer a one hour phone consultation to discuss your SAN storage questions.

Deciphering product features?

We describe all the major and minor features of today’s enterprise, mid-range and SMB class SAN storage systems including advanced features available on only a few SAN storage systems.

Reading data sheets?

Why spend hours scouring the internet, examining data/spec sheets, when our Guide compares 26 system characteristics for over 65 current SAN storage systems from all major and most minor SAN storage vendors, including hybrid and all flash array systems.

Trying to understand IO performance?

We analyze and rank SAN storage system IO performance based on industry standard block IO benchmarks like SPC-1, SPC-2, and Microsoft ESRP. We include OLTP, Email and Throughput ChampionsCharts for enterprise, mid-range and SMB storage as well as an OLTP All-Flash Array (AFA) ChampionsChart.

One Hour Consultation

With every purchase of the SAN Storage Buying Guide you also get a one hour consultation with a Silverton Consulting data storage analyst to discuss your SAN storage needs.

Primarily because it’s an objective measure, independently verified by benchmark audits, and able to be understood on multiple dimensions. Some would say that it can be gamed by throwing more hardware at it, such as more disks, SSDs or cache. We would respond yes that’s true, but all vendors can do the same. As such, it’s as level a playing field as one can find today to objectively rank and compare storage systems. Isn’t that what you want from a data storage buying guide?
It is an attempt to distill my 30+ years of storage experience into a single performance chart to identify the best performing storage systems for a given storage protocol or application. For example, the NAS Storage Buying Guide has a ChampionsCharts for both NFS and CIFS/SMB storage protocols which identify the top performers across multiple, orthogonal dimensions of IO performance. The SAN Storage Buying Guide has 10 ChampionsCharts, for OLTP, email and throughput intensive workloads for enterprise, mid-range and SMB class storage and another one for all flash arrays. Our ChampionCharts are only available in our SAN Storage Buying Guide and NAS Storage Buying Guide.
