The price of the My Passport Pro may induce sticker shock, but considering it's a portable RAID drive with Thunderbolt connections the price is plenty justified.
Western Digital gives you the choice of 2TB and 4TB options, both of which can be configured for RAID 0 or RAID 1. But ultimately the worth of the My Passport Pro will be determined by how fast it is. And it is fast -- PC World Australia found that the "write speed of 202.6MBps was very close to the read speed of 205.5MBps," and Macworld UK says the Passport Pro is "about 60% faster than any of the conventional portable hard drives that weâ€™ve reviewed recently."
For professionals who are traveling and want to protect their data without sacrificing speed, the My Passport Pro is a good choice -- just make sure your computer has a Thunderbolt port, since the Pro lacks a USB port.
