I tried getting some crude benchmarks to see if I should upgrade to a SSD. I basically went to an applestore opened up a command prompt and typed: grep -r a * grep -r a * > largefile.txt and measured the disk activity in activity monitor. Macbook Air: 250 MB/Sec peak Macbook pro 17'': 100 MB/sec peak My 2009 macbook: 18 MB/sec peak <-- wtf? With an external 10k western digital raptor drive hooked up to usb 2.0 I am getting about 40 MB/sec peak. At this point I cannot rule out that the macbook logic board is not a bottleneck, which is preventing me from buying a $400 SSD drive upgrade. I read the return policy on Newegg, there is none, only exchange. I would only upgrade if I could get performance similar to macbook air I saw today. What peak disk access do others with macbooks get?
