File load times with dynamic storage usage

A method, comprising:

• retrieving, with a processor of a computer, a list of storage devices;
• and
• in one or more iterations, writing data blocks of a file by:
• updating the list of storage devices by removing any storage devices with insufficient space to store additional data blocks;
• generating a performance score for each of the storage devices in the updated list of storage devices;
• determining a portion of the data blocks to be written to each of the storage devices based on the generated performance score for each of the storage devices;
• writing, in parallel, the determined portion of the data blocks to each of the storage devices;
• and
• recording placement information indicating the storage devices to which each determined portion of the data blocks was written.

A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform:

• retrieving a list of storage devices;
• and
• in one or more iterations, writing data blocks of a file by:
• updating the list of storage devices by removing any storage devices with insufficient space to store additional data blocks;
• generating a performance score for each of the storage devices in the updated list of storage devices;
• determining a portion of the data blocks to be written to each of the storage devices based on the generated performance score for each of the storage devices;
• writing, in parallel, the determined portion of the data blocks to each of the storage devices;
• and
• recording placement information indicating the storage devices to which each determined portion of the data blocks was written.

A computer system, comprising:

• one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;
• and
• program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to perform:
• retrieving a list of storage devices;
• and
• in one or more iterations, writing data blocks of a file by:
• updating the list of storage devices by removing any storage devices with insufficient space to store additional data blocks;
• generating a performance score for each of the storage devices in the updated list of storage devices;
• determining a portion of the data blocks to be written to each of the storage devices based on the generated performance score for each of the storage devices;
• writing, in parallel, the determined portion of the data blocks to each of the storage devices;
• and
• recording placement information indicating the storage devices to which each determined portion of the data blocks was written.
