Claim:
1. A data storage device comprising: a plurality of memory apparatuses; a searching unit suitable for searching for “k” number of physical addresses mapped to “k” number of numerically consecutive logical addresses in a mapping table; and a processor suitable for: determining whether “i” number of logical addresses are numerically consecutive to the “k” logical addresses, wherein the “i” logical addresses are mapped to “i” number of physical addresses that are numerically consecutive to the “k” physical addresses, and transmitting a first pre-read command along with first pre-read physical addresses for access to a first pre-read memory area when the “i” logical addresses are numerically consecutive to the “k” logical addresses, wherein the first pre-read physical addresses include the “i” physical addresses and one or more first read-estimated physical addresses that are numerically consecutive to the “i” physical addresses.
