Hi guys I've just bought my new rMBP 13'' 2014 with 128 gb ssd and I'm wondering about it's future and free storage space. 128 gb isn't much by any means, but I'm a light user so I hope it'll be sufficient for me. But: Which thing is better in terms of speed? - Mini USB 3.0 drive - like this one: http://www.amazon.com/Samsung-Flash-Drive-MUF-32BB-AM/dp/B013CCTOC2 or this one http://www.pqigroup.com/prod_in.aspx?mnuid=1286&modid=138&prodid=557 or; - Micro SD adapter like this http://www.amazon.com/HyperDrive-microSD-Adapter-Macbook-Retina/dp/B00PUY1PH8 with good micro sd card. What do you think about the most important thing - speed?
