Colossus for Rapid Storage (cloud.google.com)
As an object storage service, Google Cloud Storage is popular for its simplicity and scale, a big part of which is due to the stateless REST protocols that you can use to read and write data. But with the rise of AI and as more customers look to run data-intensive workloads, two major obstacles to using object storage are its higher latency and lack of file-oriented semantics.

The real failure rate of EBS (planetscale.com)
PlanetScale has deployed millions of Amazon Elastic Block Store (EBS) volumes across the world. We create and destroy tens of thousands of them every day as we stand up databases for customers, take backups, and test our systems end-to-end. Through this experience, we have an unique viewpoint into the failure rate and mechanisms of EBS, and have spent a lot of time working on how to mitigate them.

Archival Storage (dshr.org)
I'm honored to appear in what I believe is the final series of these seminars. Most of my previous appearances have focused on debunking some conventional wisdom, and this one is no exception. My parting gift to you is to stop you wasting time and resources on yet another seductive but impractical idea — that the solution to storing archival data is quasi-immortal media. As usual, you don't have to take notes.

Are SSDs more reliable than hard drives? (2021) (backblaze.com)
Solid-state drives (SSDs) continue to become more and more a part of the data storage landscape. And while our SSD 101 series has covered topics like upgrading, troubleshooting, and recycling your SSDs, we’d like to test one of the more popular declarations from SSD proponents: that SSDs fail much less often than our old friend, the hard disk drive (HDD).

Backblaze Drive Stats for 2024 (backblaze.com)
As of December 31, 2024, we had 305,180 drives under management. Of that number, there were 4,060 boot drives and 301,120 data drives. This report will focus on those data drives as we review the Q4 2024 annualized failure rates (AFR), the 2024 failure rates, and the lifetime failure rates for the drive models in service as of the end of 2024.

Cloudflare R2 Incident on February 6, 2025 (cloudflare.com)
Multiple Cloudflare services, including our R2 object storage, were unavailable for 59 minutes on Thursday, February 6th. This caused all operations against R2 to fail for the duration of the incident, and caused a number of other Cloudflare services that depend on R2 — including Stream, Images, Cache Reserve, Vectorize and Log Delivery — to suffer significant failures.

Husky: Efficient Compaction at Datadog Scale (datadoghq.com)
In a previous blog post, we introduced our Husky event store system. Husky is a distributed storage system that is layered over object storage (e.g., Amazon S3, Google Cloud Storage, Azure Blob Storage, etc.), with the query system acting as a cache over this storage. We also did a deep dive into Husky’s ingestion pipelines that we built to handle the scale of our customer data. In this post, we’ll cover how we designed Husky’s underlying data storage layer.
