Hi guys, i'm turning towards you after having searched everywhere in the forums and on the web. I have just cleaned install Mavericks on a Kingston ssd v300 and i am getting sub-par performance. Read write performance are along the lines of 80\120mb\ sec and overall performance\responsiveness\boot time is not that impressive. The Macbook supports SATA II and the SSD is a SATA III. Here is what i have done so far. -Resetted NvRam and SMC -Trim Enabler is installed and working. -Macbook firmware is updated -SSD firmware is updated. -Maverick is up-to-date. p.s I have installed it yesterday and spotlight is not indexing. The Ssd was in my pc laptop before and i was getting really good performance with it. Thanks for your help in advance !
