I'm still using Snow Leopard version 10.6.8 on my 2011 13" base MBP, but will get Lion soon. I also want to run Parallels and bootcamp for Windows 7, but right now I don't have either software. Last week I bought 8 GB of Corsair ram and they were causing kernel attacks on Snow Leopard and I returned the ram. I tried out the Seagate Momentus XT 500 GB twice. The first one I bought in May, but I had to return it because it was defective. The second one I bought last week was at a good price, but I ended up selling it because I wanted a true SSD hard drive and the store that I bought it from charges a 15% restocking fee on all returns even for exchanging for the same item or different item. Please give your recommendation on these: 1. I want to get reliable brand for 8 GB of memory. I'm not sure if I should go with Crucial or G.Skill? 2. I also want a reliable 128 GB to 160 GB SSD hard drive. I've been looking at Intel, Samsung's 470 series, and Crucial M4. Speed does not need be the fastest, but reliability and stability is more important to me. For trim support, I will be using trim enabler for Snow Leopard 10.6.8. I want to use Windows 7 with bootcamp and Paralells on the new SSD hard drive, which SSD hard drive should I get and what is a good partition size for Windows 7? I will be using an external hard drive for my music, videos, and important documents.
