We'll wager you didn't know Macworld
was going on today, did you? Pathetic jokes aside, Western Digital has lined up a pair of launches today in San Francisco to coincide with Apple's final Macworld keynote
, as we're treated to the My Passport for Mac portable HDD and the My Book Mac Edition. Truthfully, the only real difference between these drives and their vanilla counterparts is the pre-format process; with these, they both come "pre-formatted for Mac," saving you the tiresome task of converting 'em to HFS+ Journaled yourself. Additionally, these USB 2.0 drives are made to work "seamlessly" with Apple's Time Machine backup software, and they'll arrive in capacities including 320GB and 500GB (My Passport) / 1TB (My Book). Both units should be available now for between $129.99 and $179.99.
