This dataset contains the observed follow-up times and SMART statistics of 52k unique hard drives.
Daily snapshots of a large backup storage provider over 2 years were made publicly available. On each day, the Self-Monitoring, Analysis, and Reporting Technology (SMART) statistics of operational drives are recorded. When a hard drive is no longer operational, it is marked as a failure and removed from the subsequent daily snapshots. New hard drives are also continuously added to the population. In total, there are over 52k unique hard drives over approximately 2 years and 2885 (5.5%) failures.
A data frame with 52422 observations on the following 8 variables.
unique serial number of the hard drive
hard drive model
the observed followup time
temperature in Celsius
binary covariate, where 1 indicates sectors that encountered read, write, or verification errors
binary covariate, where 1 indicates a non-zero rate of errors that occur in hardware when reading from data from disk.
binary covariate, where 1 indicates there were sectors waiting to be remapped due to an unrecoverable error.
