Hi Guys, Question is in the title really. 128GBs of space is not enough for me so I need to upgrade. I figured as I was upgrading I may as well choose a Samsung Drive as it had better performance than my Toshiba (I have also looked at OWC's offerings however I have also read that by using one of their SSDs I will see a drop in Battery Life) So, If I take my MBA for service or something at the genius bar, will they notice that; 1) I have a larger SSD (as in does their system state, MBA 2011, 4GB Ram, 128GB SSD etc) 2) It's a different make etc or not the correct model (I believe the 2011MBA was shipped with both Toshiba and Samsung drives so by entering the serial number or another identifier, will the genius know I have swapped drives?) 3) If they do on the off chance discover that I have upgraded the drive will this void the warranty? Lastly, as we're on topic already, does anyone know where I can get a 256GB Samsung SSD from for the 2011 MBA apart from eBay? And are there other good offerings apart from OWC as I don't want a hit on battery life. Regards, Sal EDIT: Should have also mentioned that as a student, I wish to sell the 128GB SSD to put towards the cost of the 256GB SSD.
