It’s not that often that a new technology comes as a complete surprise to The SSD Guy, especially one that is only a year away from shipping, and that promises to revolutionize the world of storage. Yet, today a new start-up arrived that promises all of this. It has really captured my attention.
This technology is aimed at the market for long-venerated Continue reading “Replacing Tape with Flash”
It seems not so long ago that there were frequent press releases, and showings at trade shows, of “Hero” SSDs. These demonstration models (which weren’t always released as products) always had some unique and impressive attribute. They may have had a higher capacity than any SSD known to humankind, or perhaps they had phenomenal endurance. Some broke the IOPS barrier.
The SSD Guy doesn’t remember anyone Continue reading “Whatever Happened to “Hero” SSDs?”
Micron recently briefed The SSD Guy on its new 7450 SSD series, a range of high-capacity data center SSDs offered in an impressive number of capacities and form factors spanning M.2, U.3 and E1.S. The 7450 is a mainstream drive targeted at a wide variety of data center applications, including common, mixed, and random workloads.
The 7450 series is an evolution of Micron’s 7400 series which was first introduced at 96 layers and was based on Continue reading “Using 176-Layer NAND for High-Capacity Data Center SSDs”
Over the past couple of months rumors asserted that Western Digital (WDC) was in talks to acquire joint venture partner Kioxia. This is not the first time such rumors have emerged. In November of 2020, when Kioxia was expected to make its initial public offering, WDC was rumored to be in such talks, and before that, in early 2017, when Toshiba first started to plan to spin off its NAND flash and SSD business, WDC was rumored to Continue reading “Should WDC Acquire Kioxia?”
Micron has been moving very quickly for the past couple of years, and that has led to the company’s undisputed leadership in NAND flash layers and DRAM process nodes. The first to ship 176-layer NAND flash chips a year ago, and now 176-layer QLC NAND, Micron packs a huge amount of storage into a single chip. Since it uses a CUA (CMOS Under Array) architecture, the die size is perhaps Continue reading “Micron’s Tiny Little 2TB SSD”
For a long time The SSD Guy has meant to write something about the budding use of AI in SSDs. It’s an interesting approach whose time has come.
If you’re not conversant with AI, and maybe find the whole subject to be daunting, don’t worry. AI comes in many forms, and some are very simple. When major Internet firms like Google and Facebook use AI to Continue reading “Using AI to Manage Internal SSD Parameters”
While many of us, The SSD Guy included, were preparing for our New Year’s celebration, SK hynix, on December 30, closed the first phase of the company’s takeover of Intel’s NAND flash and SSD business, and created a new subsidiary that has been named Solidigm.
This is the first of two phases of the acquisition, which the companies agreed to in October 2020. With this move, SK hynix has Continue reading “Solidigm, SK hynix’ New SSD/Flash Subsidiary”
Micron announced last week (6 Oct., ’21) a family of datacenter SSDs, the NVMe 7400 series, in a roll-out that includes more product versions than The SSD Guy ever has seen in a single announcement.
Micron calls this product series: “the broadest selection of Continue reading “Micron’s Big Product Launch: The 7400 Series”
Western Digital today announced a change to the architecture of HDDs that the company showed can increase an HDD’s capacity and performance without changes to the heads, media, or mechanics. Since the design, called OptiNAND, involves a good bit of NAND flash, The SSD Guy decided that it warranted discussion here.
That, and the fact that the company said Continue reading “WDC Rearchitects the HDD”
PNY 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”
