planned obsolescence in computer hard disks.
We recently covered a study by Secure Data Recovery, an HDD, SSD, and RAID data recovery company, of 2,007 defective hard disk drives it received. It found the average time before failure among those drives to be 2 years and 10 months. That seemed like a short life span, but considering the limited sample size and analysis in Secure Data Recovery's report, there was room for skepticism. Today, Backblaze, a backup and cloud storage company with a reputation for detailed HDD and SSD failure analysis, followed up Secure Data Recovery's report with its own research using a much larger data set. Among the 17,155 failed HDDs Backblaze examined, the average age at which the drives failed was 2 years and 6 months.
Backblaze arrived at this age by examining all of its failed drives and their respective power-on hours. The company recorded each drive's failure date, model, serial number, capacity, failure, and SMART raw value. The 17,155 drives examined include 72 different models and does not include failed boot drives, drives that had no SMART raw attribute data, or drives with out-of-bounds data. If Backblaze only looked at drives that it didn't use in its data centers anymore, there would be 3,379 drives across 35 models, and the average age of failure would be a bit longer at 2 years and 7 months. Backblaze said its results thus far “are consistent” with Secure Data Recovery's March findings. This is despite Backblaze currently using HDDs that are older than 2 years and 7 months.

well that stinks. nothing is built to last anymore. well, very few things are made well, but some still are.
