Transcend’s not the first company to sell a specially-sized SD card made to expand the storage in a MacBook, but it’s entered the market with aggressive pricing and high capacities. JetDrive Lite ($49-$99) is available in different configurations for the 13” MacBook Air and every generation of 13” and 15” Retina MacBook Pro.
A simple chart helps you find the right one for your Mac, and you’ll only pay half of what PNY charges for the same capacities in its StorEDGE.
Each JetDrive Lite is available in 64GB and 128GB capacities, except for the 330 model, designed for the 13” MacBook Pro with Retina display — that one only comes in 64 gigs.
Simply pop the card into the slot, where it will stick out only enough to give you something to grab onto for removal. The cards are all rated for 95MB/s read speeds, and 60MB/s write speeds.
