Guys, I need your help, please. I'm from Brazil and bought a 120GB OWC Mercury EXTREME ™ Pro 6G SSD 2.5" to use as my primary disk. But I was taxed at customhouse when it arrived here, with a final value almost double the original. So I was thinking of selling for the same price I paid and buy a 120 Gb SATA 3 Samsung 840 Series (not PRO version) here in Brazil it. Doing this I could save around $ 100. Worth it? What are your opinions? I do not understand much about SSD's specifications. The links on the two follow: OWC: http://eshop.macsales.com/item/OWC/SSDMX6G120T/ Samsung: http://www.samsung.com/us/computer/memory-storage/MZ-7TD120BW The problem is not actually the money, I'd like to know what is the best as I bought already one and a have to change it and save some money. I have a Macbook Pro Early 2011. Many thanks! cheers!!!!
