Method of operating storage device, storage device performing the same and method of operating storage system using the same

A method of operating a storage system comprising a host device and a universal flash storage (UFS) device, the method comprising:

• transmitting, by the host device, a host performance booster (HPB) prefetch command to the UFS device, wherein a field of the HPB prefetch command comprises a logical block address information that indicates at least one logical block address for a data read operation, and a HPB prefetch identification (ID);
• transmitting, by the host device, entry information corresponding to the HPB prefetch command to the UFS device;
• transmitting, by the host device, a HPB read command corresponding to the HPB prefetch command to the UFS device, wherein a field of the HPB read command comprises a read ID, a logical block address information, and a part of the entry information;
• and
• performing the data read operation on the UFS device based on the HPB read command and the entry information,
• wherein the HPB prefetch command and the HPB read command are generated in one pair,
• wherein the read ID identifies a relationship between the HPB prefetch command and the HPB read command, and
• wherein the entry information comprises information indicating at least one physical address for performing the data read operation.
