Navigating the all-flash array storage buying process

There are many considerations when determining which all-flash array storage product best fits into your organization's plans. This buyer's guide will help guide you through the evaluation and purchasing process.


All-flash storage is taking over as the first choice to store mission-critical workloads. Solid-state drives offer distinct advantages over mechanical hard disk drives, such as reduced power consumption and increased performance.

All-flash array storage can be beneficial for numerous applications, including video streaming apps, virtual desktop infrastructures, database applications, big data and search engines, such as Google. The high-speed, low-latency, high-IOPS capabilities of all-flash storage arrays make them an appealing alternative to HDDs.

But all-flash array (AFA) storage products are not all the same, as they vary by capacity, performance, reliability and price. And, to add to the complexity, many vendors offer multiple product lines, each with several models. They are also priced at a premium compared to all-disk and hybrid arrays that mix SSDs and HDDs, adding to the importance of making the right buying decision.

Before investing in AFA storage, you need to determine what features and options the various systems offer and assess how they match your organization's needs. For example, what kind of workloads do you need to store? Are your applications read-intensive or write-intensive? How many require low latency or can tolerate high latency?

This guide can help you answer these questions and simplify the AFA storage selection process by providing a comparison of products from the leading all-flash array vendors. These products are broken down into three categories -- high-end enterprise arrays, midrange systems and NAS appliances.

Using extensive research into the all-flash array storage market, TechTarget editors focused on vendors that offered distinct AFA storage platforms, as well as several specialist vendors that developed their products from the ground up. Our research included data from TechTarget surveys, as well as reports from other respected research firms, including Gartner.

A roundup of these all-flash storage arrays provides an in-depth look at the features and functionality offered by the leading AFA products. Using this information and the accompanying product comparison chart, you can compare the specific products to find the all-flash array that will best meet your organization's needs.

Stop! Duck and Cover!

Flash is indeed fast, but under real-world workloads, most AFAs will hit a limit at scale, or load that will affect responsiveness and performance of your applications.  Trust, but verify vendor claims. A best practice is to use fully supported commercial solutions, vis-a-vis Load DynamiX,  to test before making that 6-figure decision on Storage.
