333 Million SSDs Shipped In 2020 Corresponding To 207EB, February 15th, 2021
Strong PC and channel SSD rise offsets sequential enterprise and cloud reductions due to inventory and capacity digestion

"Client DFF capacity shipments jump 18% Q/Q to 9.41EB, outpacing other segments, while client M.2 increased 11% over the same period to 25.11EB

All enterprise SSD interfaces posted sequential declines in the quarter, led by a 31% unit and 34% capacity shipment plunge for SAS SSDs Q/Q.

Enterprise SATA SSDs shipment declines reflected continued channel markets softness due to elevated inventories and reduced demand exiting the year..."

As a mature IT discipline, the pace of change in storage has slowed, but there is still plenty of buzz about underlying technologies you'll need to know about in 2021

"Like with other IT areas, data storage changes are more evolutionary than revolutionary.

Of course, the pace of evolution changes from year to year. But to get a reliable forecast on what is coming, it's useful to look at what just happened. In 2020, for example, the pace of change increased drastically due to a pandemic that changed the way most of the world conducts business.

The data center didn't hold nearly as much influence over information after offices closed and people began working from home. IT teams scrambled to ensure data remained stored reliably and securely while it spread almost as fast as the novel coronavirus that caused the change.

What does all this tell us for 2021?..."

Toshiba America Electronic Components, Inc. (TAEC) announces that Toshiba led all HDD companies in year-on-year nearline HDD average capacity growth in 2020

Toshiba followed up an astounding 55% year-on-year growth in 2019 with an impressive 35% year-on-year growth in 2020 to lead the industry for a second consecutive year, according to Trendfocus's data.

'Toshiba has done an admirable job of leveraging its industry-first 9-disk helium design to introduce competitive nearline HDD products in a timely fashion. This has been the cornerstone in the company's ability to launch higher capacity nearline HDD programs,' stated John Chen, VP, Trendfocus, Inc. 'Toshiba's 9-disk helium-sealed HDD platform has enabled the company to achieve the highest five-year CAGRs for nearline HDD Units, exabytes, and average capacity shipped through 2020.'

Object store acquisitions by DataCore, Nvidia and Quantum underscore the growing importance of object storage to address enterprise workloads ranging from archives to analytics

"DataCore Software's recent merger with Caringo threw object storage into the spotlight again -- a year after Nvidia and Quantum completed acquisitions of similar scale-out technology to store enormous volumes of data.

Although the trio of acquisitions fills differing needs for each vendor, they collectively reflect the expanding number of use cases that object storage now targets. Object stores have traditionally focused on backups and archives of cold, unstructured data. But more recently, higher performing options -- including some using flash technology -- are increasingly becoming a consideration for AI, machine learning and analytics workloads..."

Open Source Definitely Changed Storage Industry, February 16th, 2021
With Linux and other technologies and products, it impacts all areas

"It's not a breaking news but the impact of open source in the storage industry was and is just huge and won't be reduced just the opposite.

For a simple reason, the developers community is the largest one and adoption is so wide. Some people see this as a threat and others consider the model as a democratic effort believing in another approach. Let's dig a bit..."

Toshiba MG09 Series 18TB HDDs Announced
StorageReview, February 18th, 2021
3.5-inch form factor, 7,200 RPM and either SAS or SATA interface

"Toshiba Electronic Devices & Storage Corporation announced new 18TB HDDs in its Toshiba MG09 Series. According to the company, the MG09 Series features Toshiba's third-generation, 9-disk Helium-sealed design and Toshiba's innovative Flux Control - Microwave Assisted Magnetic Recording (FC-MAMR) technology, to advance Conventional Magnetic Recording (CMR) density to 2TB per disk, achieving a total capacity of 18TB. This also marks Toshiba's first HDD with energy-assisted magnetic recording..."

HDD volumes to decline by 10x from 2021 to 2026

This research examines 6 important storage premises around NAND flash and tape replacing HDDs .

The premises are:

1 Wikibon projects that flash consumer SSDs become cheaper than HDDs on a dollar per terabyte basis by 2026, in only about 5 years (from 2021).

2 It projects that HDD volumes will continue to decline rapidly by a factor of 10 by the end of this decade.

3 Innovative storage and processor architectures will accelerate the migration from HDD to NAND flash and tape by using consumer-grade flash.

4 As a result of 3, flash is lower cost over 5 and 10 years for almost all file-based workloads than HDD, when storage management and space are factored in.

5 Flash has already overtaken HDDs in total storage petabytes shipped. Wikibon projects the investments in flash fabs and hybrid flash/tape technologies will complete the takeover of HDD by the end of this decade.

6 The 10-year and 5-year business cases for QLC flash for implementation in 2021 and beyond for exascale NAS environments are compelling.
