Samsung patents storage method that predicts file parts to speed up reads

Samsung describes a storage device that uses a specific data field in the Universal Flash Storage (UFS) protocol to identify how a file is split into pieces. The controller reads this information to fetch the remaining parts of the file in advance, reducing the time it takes to load the complete file.

Why it mattersThis could make loading large files on phones or laptops feel slightly snappier by reducing the wait time between data requests.

In the filing’s own words

A storage device may include a non-volatile memory configured to store one file as a plurality of file fragments, and a storage controller configured to receive a read command with respect to the plurality of file fragments from a host through UFS protocol information unit (UPIU), and perform prefetching on the plurality of file fragments based on file fragmentation information included in an extra header segment (EHS) field of the UPIU.

What exactly they claim (claim 1)

1. A storage device, comprising: a non-volatile memory configured to store one file as a plurality of file fragments; and a storage controller configured to receive a read command with respect to the plurality of file fragments from a host through UFS protocol information unit (UPIU), and perform prefetching on the plurality of file fragments based on file fragmentation information included in an extra header segment (EHS) field of the UPIU.
