New SSDs Dedicated to Chia

Photo of terra cotta Chia Pet bust of Joe BidenPNY sent The SSD Guy an interesting press release about a new SSD designed for use in Chia plotting operations.

For those unfamiliar with Chia, it’s not the silly Chia Pets (like the Joe Biden Bust in this post’s graphic) that use vegetation to replicate hair, but is instead a new cryptocurrency somewhat similar to Bitcoin.  We are told that Chia uses “Proof of Space and Time” models for mining rather than the “Proof of Work” models that Bitcoin employs.  While that means that Bitcoin’s approach is compute intensive, Chia’s takes advantage of unused Continue reading “New SSDs Dedicated to Chia”

Computational Storage Hits the Mainstream

Chart showing two lines on a graph of performance vs number of SSDs. With "Scale In" the performance is proportional to the number of SSDs. With a standard server the performance diesn't change. With 16 SSDs the performance is 4 timeas as much, and with 32 SSDs it's 8 times as much.There’s an idea that has been kicking around for a number of years, and it seems now to be gaining traction.  The idea is to use the inherent smarts and high available bandwidth within an SSD to perform functions that would normally be done by a server’s processor thereby reducing the load on the processor while minimizing the amount of data that needed to make a round trip from the SSD to the processor and back for some trivial function.

Such data movement is said to consume a very Continue reading “Computational Storage Hits the Mainstream”

Failures Plague SSDs

Pomander from Organic AuthorityOver the past year there has been a rash of SSD failures unmatched by any prior year.  This came to a head a month ago when Apple’s M1 Mac started to show undue SSD wear.  It seems that people trapped at home and working remotely have taken up new habits on their notebook PCs (most of which now use SSDs) and these habits are causing their SSDs to wear out faster than they have in other, more normal years.

The “Work from Home” phenomenon has not only caused Continue reading “Failures Plague SSDs”

Intel Discontinues Optane Consumer SSDs. Is This Important?

Intel Optane Memory M10 Press PhotoOn Friday, January 15, Intel announced the discontinuation of certain of the company’s Optane SSDs for consumers PCs.  Naturally this is making Optane users curious about the future of the entire product line.  Is this a big move?

In a word: “No.”  It’s a relatively small part of overall Optane shipments, and it is probably Continue reading “Intel Discontinues Optane Consumer SSDs. Is This Important?”

Why Did Intel Sell its SSD Business?

Intel recently sold its NAND flash business, which was mainly producing SSDs, to SK hynix, a Korean competitor.  Some people have asked the SSD Guy why did Intel do this? The company had highly-regarded products that could command top prices.  Since Intel’s NAND flash fab is in Dalian, China, one person even asked if the divestiture could have been in response to the US-China trade war.

A better question is: “Why did Intel Continue reading “Why Did Intel Sell its SSD Business?”

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”

What’s Software-Enabled Flash?

abstract eye-catching imageThere have been numerous changes to SSDs since they moved into the mainstream 15 years ago, with controllers providing increasing, then decreasing endurance levels, and offering greater, then lesser levels of autonomy.  What has been missing is any ability for the system to determine the level of performance that the SSD provides.

Recently Kioxia, the company formerly known as Toshiba Memory, announced Continue reading “What’s Software-Enabled Flash?”

High Availability in an m.2 Format

Photo of finger pusing on hinge in center of m.2 HA SSDThe m.2 SSD format has become wildly successful in the data center for use as a boot drive and even in SSD arrays.  The m.2 format supports either the SATA or the NVMe interface,  Something that has been missing, however, is a version of this format for high-availability (HA) systems.  These are mission-critical systems that cannot fail, no matter what.

Until today HA systems had to Continue reading “High Availability in an m.2 Format”

New Book Explains Persistent Memory Programming

Cover picture of Intel's Persistent Memory bookAt January’s SNIA Persistent Memory Summit Intel was promoting a book titled: Programming Persistent Memory.  This book, aimed at programmers, explains how to develop applications programs that take advantage of persistent memory (PM) to avoid slower persists to SSDs, and also shows how to use Intel’s Optane DIMMs to increase a system’s main memory size.

On the software side the book explains Continue reading “New Book Explains Persistent Memory Programming”
