Hi frnds im giving a advice not to buy WD My Passport portable drive Essential se 1 tb not be the fastest drive available, and it has not having good speed docks like the Must-have Seagate HDD. But it does offer something you’ll find in few other portable drives: capacities of up to 3TB .an impressive portable hard drive for its physical size and capacity” . The Seagate Backup software is very good utility go for it but dont buy wd hdd
