Transcend Information (http://tinyurl.com/owzyesd) has launched its JetDrive Lite series of expansion cards aimed at MacBook Pro  with Retina  display and MacBook Air  users. There are four different models offered in 64GB and 128GB capacities.

Transcend’s new JetDrive Lite cards are tailor-made to have a flush profile with each specific model while providing a way to increase available storage. The 128GB card, for instance, can store over 60,000 high-resolution photos, 32,000 MP3 songs, 32 hours of Full HD video, or seemingly limitless number of documents.

When inserted into the card slot of a compatible MacBook Pro with Retina display or MacBook Air, the low-profile JetDrive Lite will not stick out like an SD card and can be left in place for on-the-go storage, according to the folks at Transcend.
Manufactured with MLC NAND flash chips, the expansion cards boast read and write speeds of up to 95MB/s and 60MB/s respectively.

The JetDrive Lite Series of expansion cards are available in 64GB (US$49) and 128GB ($99) capacities. All have a limited lifetime warranty.
