Hey guys, Despite some issues getting my 2011 mini to run dual SSDs (http://forums.macrumors.com/showthread.php?t=1725723), everything was running fine. Hadn't run a speed test in a while so can't be positive it is directly related to Yosemite, but I recently realized that my primary/boot SSD (Samsung 840 250GB) is running at only 40MB/s W, 120MB/s R vs. my secondary SSD (Samsung 840 EVO 250GB) at 440MB/s W, 510MB/s R. Hardware all seems fine, checks out in disk utility, no SMART errors or anything. One thing possibly worth noting, the primary (problem) SSD was recently filled to capacity while backing up my new iPhone 6, but now that I have deleted some files it is back down to 50% capacity (roughly the same for the secondary). Been messing with this all weekend, I even tried enabling TRIM by disabling the KEXT signing, but speeds were still the same. Could this be related to upgrading to Yosemite? Temporarily filling the SSD to capacity? Anyone have any suggestions on how to remedy it?
