The 16TB Seagate (model: ST16000NM002J) had zero failures last quarter as well, and the 8TB Seagate (model: ST8000NM000A) has had zero failures since it was first installed in Q3 2022, a lifetime AFR of 0%. That said, for two of the drive models listed, posting zero failures is not new. When reviewing the table, any drive model with less than 50,000 drive days for the quarter does not have enough data to be statistically relevant for that period. This leaves us with 236,893 hard drives grouped into 30 different models to analyze. For our evaluation, we removed 385 drives from consideration as they were used for testing purposes or were drive models which did not have at least 60 drives. In that quarter, we tracked 237,278 hard drives used to store customer data. Let’s start with reviewing our data for the Q1 2023 period. Along the way, we’ll share our observations and insights on the data presented and, as always, we look forward to you doing the same in the comments section at the end of the post. We also dig into the topic of average age of failed hard drives by drive size, model, and more. Today, we’ll focus on the 237,278 data drives under management as we review their quarterly and lifetime failure rates as of the end of Q1 2023. ![]() ![]() The failure rates for the SSDs are analyzed in the SSD Edition: 2022 Drive Stats review. Of that number, 4,400 are boot drives, with 3,038 SSDs and 1,362 HDDs. During the last 10 years, a lot has happened with the where, when, and how of our Drive Stats data, but regardless, the Q1 2023 drive stats data is ready, so let’s get started.Īs of the end of Q1 2023, Backblaze was monitoring 241,678 hard drives (HDDs) and solid state drives (SSDs) in our data centers around the world. ![]() More precisely it was 10 years ago, and the galaxy was just Northern California, although it has expanded since then (as galaxies are known to do). A long time ago in a galaxy far, far away, we started collecting and storing Drive Stats data.
