Three Truths About Hard Drives and SSDs

An examination of the claim that flash will replace hard drives in the data center

“Hard drives will soon be a thing of the past.”

“The data center of the future is all-flash.”

Such predictions foretelling hard drives’ demise, perennially uttered by a few vocal proponents of flash-only technology, have not aged well.

Without question, flash storage is well-suited to support applications that require high-performance and speed. And flash revenue is growing, as is all-flash-array (AFA) revenue. But not at the expense of hard drives.

We are living in an era where the ubiquity of the cloud and the emergence of AI use cases have driven up the value of massive data sets. Hard drives, which today store by far the majority of the world’s exabytes (EB), are more indispensable to data center operators than ever. Industry analysts expect hard drives to be the primary beneficiary of continued EB growth, especially in enterprise and large cloud data centers—where the vast majority of the world’s data sets reside.

Storage Technologies & Practices Ripe for Refresh – Part 2

So much of what we discuss in SNIA is the latest emerging technologies in storage. While it’s good to know all about the latest and greatest technologies, it’s also important to understand those technologies being sunsetted. In this SNIA Networking Storage Forum (NSF) webcast series “Storage Technologies & Practices Ripe for Refresh” we cover technologies that are at (or close to) being past their useful life. On June 22, 2021, we’ll host the second installment of this series, Storage Technologies & Practices Ripe for Refresh – Part 2 where we’ll discuss obsolete hardware, protocols, interfaces and other aspects of storage. We’ll offer advice on how to replace these older technologies in production environments as well as why these changes are recommended. We’ll also cover protocols that you should consider removing from your networks, either older versions of protocols where only newer versions should be used, or protocols that have been supplanted by superior options and should be discontinued entirely. Finally, Read More
