Methods, systems, and computer-readable storage media for performing scattered atomic I/O writes in a storage device. A list of block I/O write requests to be completed as an atomic unit is received from a requester with at least two of the block I/O write requests specifying non-contiguous data locations on a storage media. The plurality of block I/O write requests are buffered in a write buffer with each buffer entry marked as having an invalid state, wherein marking a buffer entry as having an invalid state prevents it from being flushed to the storage media. Upon buffering all of the plurality of block I/O writes, all of the buffer entries are marked as having a valid state at the same time. Upon marking all of the buffer entries as having a valid state, successful completion of the list of block I/O write requests is acknowledged to the requester.
