With a 13" MBP on the way, I've caught myself up on the EFI Firmware Update 1.7 issue and decided that instead of risking the bad performance (beachballs) or incompatibility with non-Apple drives, I'm going to stick to the 1.6 firmware and deal with 1.5Gb/s transfer rates. Question 1: Is 1.5Gb/s limitation enough of a reason to not get an SSD? Take the Intel X25-M for example. In benchmark tests its read speed is 254MB/s and its write speed is 101MB/s. The way I understand it, the read speed would be limited by 26% on a 1.5Gb/s (187MB/s) but the write speed would be unaffected, and random read/write speeds also unaffected. Is this correct? It's still significantly faster than a WD Scorpio Blue 500GB for example, which has 84MB/s transfer rates. Question 2: Should I buy a second-hand Intel X25-M 80GB G1 ($170, used for 6 months)? Considering 80GB G2s are going for $289 right now, I'm quite tempted, but I have some concerns: 1) It's been used for 6 months already. But since it "can support 100GB of new data every day for 5 years at a bare minimum" this isn't a big deal, right? 2) its ability/inability to run Boot Camp. Some people here had issues with installing Boot Camp on G1 models. Has anyone with a G1 been able to install Windows? This is critical because I need to use Windows for work. 3) No TRIM. I know OS X doesn't support TRIM yet but I would be doing some work in Windows 7 (involves PostgreSQL databases). Some people say there will be a decrease in performance when the drive fills up, and others say it will "level out" - which is true? If I shouldn't buy this particular SSD, what alternative SSDs would you recommend me looking into? Question 3: If I shouldn't get an SSD at all due to the 1.5Gb/s limitation, would my best option be running two internal 500GB Scorpio Blue in a RAID-0 setup?
