Hi Folks, I just bought a 17'' Macbook Pro '11. Got it with the default hard drive option "750GB Serial ATA; 5400 rpm". I'm not too savvy with my knowledge of hard drives but would appreciate some tips. Question 1: What's the read speed, and what's the write speed of these things? Is it possible to find out each of those numbers seperately as opposed to a "data transfer rate" which is ambiguous. Question 2: If I buy an SSD, for example the 128GB Crucial m4 2.5-inch SATA 6GB/s, which seems to get really good reviews and bang for buck, which has a read speed of 415mb/s, how does that compare to the read speed of the normal hard drive? And same question regarding the write speed. Question 3: Is there a "step by step" tutorial or video that someone can recommend for how to upgrade the SSD hard drive in one of the new macs? Thanks in advance for any info.
