Reading the praises for ssd's i ordered one from kingston last month for my macbook 5,1. Last week I installed it and built the os from scratch as I needed a fresh install. (By the way I have 6 gb ram). At first is seemed like a BMW after riding donkey for years. However after a week the mac seemed a bit slow and i opened blackmagic disk speed test. It gives me around 90 MB/s Write and 124 MB/s read. Now i look at my old drive with 7200 RPM and its around 95 / 95 for both. After a research i realized that my disk is working in 1.5 Gigabit negotiated link speed mode whereas it gives me a 3 Gb link speed. I discovered that this problem was solved in newer models. It seems that they want me buy a new computer however I like my macbook and i want to get what i paid for. I am disappointed by this SSD stuff. Now after a week I feel its getting slower than before. Do you have any suggestions? How can I raise the speed of my SSD? Why is it getting slower?
