When it comes to external storage, there are a number of interfaces that a drive can use. They range from USB 2.0 and 3.0 ports to eSATA and Thunderbolt among others. WD has been making external storage solutions for a long time.




WD has made drives in the past that use Thunderbolt for connectivity. The company has unveiled the new my Passport Pro that is the first drive to be bus powered and offer dual drives in one enclosure. On Mac computers, the drive has user selectable RAID functions.


The My Passport Pro is offered in 2TB and 4TB capacities. WD says that the new drive is the only bus powered dual drive offering on the market. It offers speeds of up to 233MB/s and can be set in RAID 0 or RAID 1 configurations.


Inside the aluminum enclosure of the My Passport Pro are two 2.5-inch HDDs. The 2TB version of the drive sells for $299.99 with the 4TB version selling for $429.99. Both capacities of the drive are available now.
