I'd like to buy a portable solid state drive for a gift for a friend who has a new MBP with USB-C ports. He purchased it with a 512GB SSD and hoped to keep his large iTunes library as well as video editing projects on a fast external drive. Unfortunately I have not been able to find any portable Thunderbolt 3 SS drives with USB-C ports except for one from laCie. That is $2,000 and did not get terribly good reviews. Can someone suggest where to purchase one of these items? Thank you.
