I have a mid 2011 27" iMac i7 with the BTO 256GB SSD and 2TB HDD. It feels like it is running slower than when new, when launching apps and also restating. I've run Blackmagic on it and I'm getting 150MB/s write and 199MB/s read. I'm sure this is slower than when new. (The HDD is getting 77MB/s read and write) Are other people getting similar speeds or is my SSD slowing down? Is there anything I can do to speed it up? I've not got trim enabler running on it, I assumed BTO SSD's didn't need it. Any help or advice appreciated!!
