Hey guys I know I'm posting a few questions for the second time, but I need some good answers soon because I'll get my SSD tomorrow and there are still some points that are not really clear to me. After reading all kind of information on the net, I narrowed down the following drive options for my new 15" MBP 2.2GHz: SSD: Intel 320 160GB OR Intel 510 120GB (Mainly because I'm looking for a reliable product + I can update the firmware with my Mac) HDD: 750GB WD Scorpio Black 7200RPM Open questions: 1. Did the recent EFI update resolve the SATA3 issues with the Intel 510? Is it now working as it should? Or is it still the same gambling? If it is still unstable, I'll definately go for the 320 series...... 2. Where do I install the HDD? When choosing the 510 series, of course the SSD will be sitting in the HDD bay and the Scorpio in the optibay. But what is the best configuration when installing the Scorpio Black and a SATA2 drive? Will the Scorpio be any noisier / more vibrating in the ODD bay? Are there some Cons/Pros about power management, sleep or idle behaviour? Thanks for your fast answers, I really appreciate it!
