Enterprise HDDs Hit 20 TB, Boost Throughput In 2020
SearchStorage, February 13th, 2020
While waiting for HAMR to drop, we have more immediate spinning disk developments to watch out for in 2020, such as dual-actuator and shingled drives

"Flash and new memory technologies don't have a stranglehold on all the storage hardware innovation. Even age-old spinning disk will see new twists in 2020 and beyond.

Technologists and storage analysts predict the ramp of new hard disk drives (HDDs) with dual actuators that can boost input/output operations per second. That can help in use cases such as hard drive rebuilds and analytics applications. Experts also expect shingled magnetic recording (SMR)-enabled HDDs to become more commonplace for applications that write data sequentially. SMR HDDs have data tracks that partially overlap to increase areal density and capacity..."


HDD Failure Rates Based On 124,956 HDDs At Backblaze

Only one to have no failure: 4TB Toshiba model MD04ABA400V

"As of December 31, 2019, Backblaze had 124,956 spinning HDDs. Of that number, there were 2,229 boot drives and 122,658 data drives.

This review looks at the HDD annualized failure rates (AFR) for the data drive models in operation in our data centers. In addition, we'll take a look at how our 12 and 14TB drives are doing and get a look at the new 16TB drives we started using in 4Q19. Along the way we'll share observations and insights on the data presented..."


Regular HDD Stats readers will recall that our blog post about 3Q19 explained that we planned to take a closer look at some drive failures we were seeing at the time and report back when we knew more

"Well, we've been monitoring the situation since then and wanted to update you on where things stand. Despite the fact that HDD Stats for 2019 are just around the corner, we decided to share this information with you as soon as we could, rather than waiting for the next post. In summary, this year (and going into the next year) we expect to see higher failure rates in some of our HDDs and we will be migrating some drives to newer models. Below, we'll discuss what's going on, what we're doing about it, and why customers shouldn't worry..."

On-premises object-based storage is replacing traditional storage in areas such as streaming, big data and IoT. Get the latest on how this technology is being used

"Don't look now, but on-premises object storage is being used for more than just secondary storage. It's easy to see why many storage managers still view it mostly in terms of secondary storage, since the technology fills the role previously dominated by tape, the longtime go-to secondary storage media. Yet, on-premises object data storage offers opportunities that extend far beyond tape backups.

With on-premises object storage, data can be accessed in milliseconds, not minutes. The technology offers streaming performance that can grow along with the system, a leading reason why it now provides back-end storage for video services, such as Netflix and Amazon Prime..."
