I' asking this because while i reach 260mb/s reading, i got just 50 mb/s writing, and this is for sure NOT correct. I did some search but nothing useful appeared
my controller is SATA II and it correctly show boot "Link speed" and "Negotiated Link speed" at 3 Gigabit.
So i'm wondering WHY DISK SPEED TEST shows me just 50 MB/s
Shootists007: i've found out the problem.
My SSD is a Crucial M4 256GB.
TRIM support is enabeld via the utility.
I'm using Blackmagic Disk Speed test, now i get 201MB/s write and 260MB/s read.
The problem, as i've rad on some forum, is that the nvidia controller that mounts Macbook PRO 5.1 is faulty and if you reboot your machine you get those low speeds.
I've simply shutted down the macbook and turn it on again and speed seems to be more coherent...
