I just tried several SSDs with my 2010 Macbook Pro with i7 cpu and Sata 2 controller and im trying to decided which one is a keeper. Right now im torn between Corsair F115 with sandforce Sata 2 controller and Crucial C300 128gb with Sata 3 controller. All things considered, trim support in OSX is actually available due to latest third party developments(see macrumors), so sandforce controller has minimal advantage and I actually got C300 for less and got more space to boot. Id really like to keep it. BUT BENCHMARKS Im running two tools for OSX that I found: XBench and AJA Systems Test As you can see from the screenshots below, with XBench, C300 wins on all counts, whereas with AJA Systems, the read speeds reported are half of those of Corsair F115. Has anyone run into similar results with these same SSDs? Whats a good consistent SSD benchmark for OSX? I attached images of the OSX Profiler when these SSDs were plugged in. Corsair AJA Test: Crucial AJA Test: Notice half as fast write speed Corsair X-Bench Crucial X-Bench: Numbers show it being faster than Corsair at writes as well as reads Corsair Profiler to show Sata Link speed, etc and with Crucial SSD: Note: I posted same question on Crucial SSD forums, but my Corsair results were removed by moderators rendering my question sort of meaningless.
