Ive currently got a 13" MBP Mid 2009 with 4GB and I'm thinking about upgrading the HDD to a SSD to get a bit more lifespan out of it. Ive only done a little reading but occasionally I come across posts which imply there is an issue using SSD's in the mid 2009 models. Is this correct or is it misinformation? I can't really find anything specific, just odd comments about EFI Versions etc. I realise its old spec SATA (SATA II?) so won't get the full performance benefits that some SSDs offer (SATA III?) but I was considering the Samsung 840 EVO MZ-7TE250BW Can anyone give any advice if this would be suitable for my machine, or any other issues using SSD and this model of machine? *I know I will have to enable TRIM Thanks.
