Abstract
A technique rebuilds data from a group of hard disk drives (HDDs). The technique is performed in data storage equipment and involves storing data on a group of HDDs. The group of HDDs is constructed and arranged to maintain data availability following a HDD failure. The technique further involves, after storing the data on the group of HDDs, detecting a failure of a particular HDD of the group of HDDs. The technique further involves, after detecting the failure of the particular HDD, rebuilding a particular portion of data onto a solid state drive (SSD) based on other portions of the data residing on remaining HDDs of the group of HDDs other than the particular HDD, the particular portion of the data having resided on the particular HDD that failed.
