Sub-par performance with SSD Macbook mid 2009

[rhetorique]

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 !

best answer i've found yet ... this is very frustating

it seems as you can get proper speed in mountain lion... is it still relevant and safe in 2015 ? could consider doing the switch if that doubled my speed...
