NVMe-oC: Wolley’s New Take on CXL-Based SSDs

Vertical block diagram with a CPU at the top, a CXL link below, and a dashed-line box below that. The Dashed box contains two side-by-side devices: NVMe NAND and Memory. Two bidirectional arrows communicate from these two devices through the CXL link to the CPU. A little red arrow shows data moving directly from the NAND into the memory while bypassing CXL.With all the recent interest in CXL, and its ability to connect a processor to any memory, no matter the speed, it’s only natural that someone would try using it for SSDs.  This notion is the basis for the Memory-Semantic SSD, or MS-SSD.

But MS-SSDs suffer from the same problem as SSDs, hard drives, and other mass storage.  The basic concept requires Continue reading “NVMe-oC: Wolley’s New Take on CXL-Based SSDs”

A lot of folks believe that when Intel’s Optane is gone there will be nothing left but the story of its rise and fall.  That is far from the truth.  Optane has created a legacy of developments that will find use in computing for quite some time.

In this three-part series The SSD Guy blog reviews Optane’s lasting legacy to reveal six changes that it has brought to computing architecture in its short lifetime.

Each of the three parts covers two new developments:


This third and final post will cover Optane’s new approach to memory expansion and the new security Continue reading “Optane’s Legacy, Part III: Memory Expansion and Security”

How Many Optane SSDs has Intel Sold?

Cartoon of a detective looking through a magnifying glassIf you’re an industry analyst like The SSD Guy you find that useful data can come from unexpected places.  When Intel announced the sale of its NAND flash business to SK hynix this month the company also provided useful information about Optane SSD sales.  You have to know a little bit about Intel’s organizational structure to understand.  Let me explain.

The SSD part of Intel’s Optane business has been Continue reading “How Many Optane SSDs has Intel Sold?”

Emerging Memory Market to Hit $36 Billion by 2030

The SSD Guy is pleased to announce the release of a new report co-authored by Objective Analysis and Coughlin Associates named: Emerging Memories Find Their Direction.  In this report we show that emerging memories, MRAM, ReRAM, 3D XPoint, and other technologies are well on their way to reach $36 billion of combined revenues by 2030.

These changes will Continue reading “Emerging Memory Market to Hit $36 Billion by 2030”
