For more than a decade, IT industry analysts have been predicting the demise of hard disk drives. The first all-flash array for enterprise applications was introduced in 2011, and within a few years organizations were using flash for Tier 0 and Tier 1 data. The performance gains were so great that it seemed natural to assume HDDs would soon be replaced.
However, organizations didn’t see value in using flash for applications that didn’t need that level of performance. In most data centers, HDDs are considered a mainstay for Tier 2 and Tier 3 data.
Fast forward to 2024. Those attitudes are changing as flash storage evolves and prices continue to come down. Flash is comparable in price to HDDs for some capacities. As manufacturers roll out more high-capacity flash storage, economics will soon drive the transition to all flash. Other factors are influencing that decision as well.
Faster Performance, Greater Resilience
Performance has been the primary selling point for all-flash arrays. Flash provides access times in the low milliseconds or even microseconds, and gigabit-per-second throughput. It’s a matter of physics: HDDs have moving parts that strictly limit their speed. Solid-state flash drives don’t.
The growth of AI workloads is increasing demand for flash. Deep learning models require vast amounts of data to train their algorithms. High-performance storage is needed to reduce model training time and provide low-latency access to inference engines for real-time decision-making. Flash’s ability to perform random data access quickly makes it ideal for AI applications.
Resilience is another key feature of all-flash arrays. Because they have no moving parts, solid-state drives are less prone to failure than HDDs. If a failure does occur, flash drives can be rebuilt in minutes or hours compared to days or weeks for HDDs. The latest all-flash arrays also have built-in cyber resilience. For example, the IBM FlashSystem monitors I/O and uses machine learning to detect anomalies such as ransomware.
A More Sustainable Future
All-flash arrays help organizations meet their sustainability objectives in three ways. Flash has significantly lower power requirements than HDDs. Less power means less heat. Additionally, flash drives are more compact than HDDs, packing more data in a smaller footprint. Less data center floor space again equates to lower energy costs.
These features are increasingly important in the age of AI. AI workloads consume a lot of power and thus generate a lot of heat. AI servers tend to have a larger footprint than those used for less demanding workloads. All-flash arrays help offset some of the energy consumption and cooling requirements and enable organizations to pack more data in a smaller space.
By deploying flash storage throughout the data center environment, organizations can gain greater consistency and therefore reduce complexity. This is especially valuable in hybrid cloud environments, which require IT teams to manage on-premises systems and multiple cloud providers.
How Technologent Can Help
Technologent’s data center experts stay abreast of changes in flash technology and assess new solutions as they come on the market. Most recently, IBM Practice Manager Michael Schroll evaluated the new IBM FlashSystem 5000.
“Using the IBM FlashSystem 5000 technology is easy and simple to install,” Schroll said. “We are excited to show our customers the new FlashSystem 5300 and its improved cyber resilience capabilities, all within a 1U footprint. It is amazing to think of the high performance, increased capacity, and enterprise-grade features users will be able to access at this price point.”
Will all-flash arrays replace HDDs in the data center? Falling prices, increasing density and the rise of AI workloads suggest that they will. Let Technologent help you get ahead of this trend and take full advantage of the performance, resilience and sustainability benefits of flash.
