I was thinking to purchase the Vector 256GB for my 2011 MBP (SATA III) As we all know, its competitor, Samsung 840 Pro is very famous as well. The thing is Im not a huge fan of Samsung and their product. Didnt have really great experiences with them in the past. I was committed to buy the Vector but the price is extremely high on it. Even at B&H or Amazon, the retail price is higher on the 840P yet still less expensive than the Vector. So I decided to look at the Samsung as well and leave the hatred behind. Performance wise, what do you guys think? Vector vs 840 Pro, which would be more reliable, more faster, and more stable? Cost performance wise, probably the 840. But would the $60+ price tag give me more advantage on the Vector? Users who had experience with 840 or Vector, please tell me the pros and cons with your MBP. Thanks in advance.
