sata 3 SSD running on sata 2 speeds ??? G53

[maej72]

hello guys 😄
im having a bit of problem here, i bought mushkin enhanced chronos 120gb sata 3 6 gb/s SSD, so i installed it in my G53sw-a1, and installed a fresh windows 7 on it..... the problem is the intel 6 series c200 (HM65 chipset) supports sata 3 6 gb/s, but i get the sata 2 3 gb/s speeds (200 MB/s read/135 MB/s write) i dont know why??

the ssd speeds are up to 550 MB/s read and 540 MB/s write and i've read some reviews on it and other users get around 400 MB/s read and write.

* in case you're wondering it's installed on the second sata port which supports 6 gb/s speeds and the the original seagate 750gb 7200 rpm hdd is on the first port.

** and there is something i dont really get, intel says the chipset supports two 6 gb/s drives or six 3 gb/s devices.
i dont get this point at all. do they mean if i have three devices connected to the sata ports all of them are going to run on 3 gb/s speed or the first two ports support 6 gb/s speed and the other four ports going to run on 3 gb/s speed regardless of how many ports are being used???

by the way the third port is being used by the dvd drive.

and i dont know if im using the intel AHCI DRIVERS OR MICROSOFT AHCI DRIVERS, the "as ssd" program says "msahci", but i really dont know

Does DIsk Mnaagement report a single system partition, in the SSD, or does it also show a system partition on the HDD?

no the disk management is fine shows the ssd as the system partition and hdd as dynamic disk that has simple partitions, but the problem is the RST, the IAstorUI tells me that the hdd is the system disk.
here's the report :

OMG i just tried ATTO disk benchmark and i got 540 MB/s read and 510 MB/s write, but the other programs like "as ssd" and "crystaldisk" don't go beyond 200 MB/s. what do you think should i trust ATTO's??

edit: also crystaldiskbench gave me the 450 mb/s speeds, but when i changed the mode from random to 0fill
so thank you so much, i guess there wasn't a problem at all from the beginning, i really appreciate your patience and help 😄
how can i give you rep points ??
