Hey guys, Recently purchased a OCZ Technology 240 GB Vertex 2 Series SATA II 2.5-Inch Solid State Drive (SSD) OCZSSD2-2VTXE240G for my 2010 13" MBP as well as an OWC Data Doubler. Prior to my SSD, I had a Seagate Momentus XT 500 GB 7200RPM (ST95005620AS) which I kept in my primary HDD bay and installed the SSD in the optical bay with the Data Doubler. Though I love the speed of the SSD, I'm having a huge drain on my battery... I can literally watch the % battery life remaining drop a percentage point every few minutes. My MBP went from 5.5-7 hours of usage to 2.5-3.0 hours of normal usage (browsing, word processing, etc.) I'm not sure, but I think this may have to do with the fact that the Seagate Momentus is battery hog, or, does it have anything to do with the fact that I put the SSD in the optical bay and left the traditional HDD in the primary bay, perhaps the SSD is not receiving the proper power management commands? I read it's best to put the SSD in the optical bay as to allow the OS to send the proper command to the traditional HDD in case of sudden acceleration (due to an accidental drop). Was I wrong? This leads me to the following questions: 1. Need a recommendation for a traditional HDD for my storage drive. Anything 500GB or over is great. Would like at least a 5400 RPM drive (can go with 4200 if the power savings are significant). I'm considering the WD 750GB WD7500BPVT (seems to have some very low published power requirements) or some of the drives mentioned in the post below. I'm most familiar with WD/Seagate, but would gladly take any other recommendations based upon the fact that I'm looking for a decent storage drive with lowest power hit on the battery. 2. Do SSDs have power management built in? If so, would it be better for me to put the SSD in the primary MBP hard drive bay and the traditional HDD in the optical bay? Does it even make a difference? Since some of the drives that I'm looking at offer some sort of drop protection, does it make a difference? 3. Have any other users seen such a power drainage from using a traditional HDD with a SSD in their MBP? Thanks in advance guys!
