i have seen some benchmark tests with similar ssd s and makbooks and mine is really really slow. 27 mbs write and 100 mbs read. i have the 128 gb version. the laptop is a mid 2012 i5 with 8 gig ram. i m not sure that buying another sad will solve the problem, so i m not willing to spend the money before i know for sure. thanks
mac's serial number is C02HTQ4ADTY3 and this is what i could find about the ssd: Apple ssdSM128 revision VAM0BA1Q. this is not the ssd that came with the macbook, i installed it. from what i could find on the internet, this ssd was shipped with MacBooks Air and is rather slow. But still, it seems too slow..
