I own an inspiron N5010 ( i7) and recently i purchased an external esata capable HDD. ( APACER AC601 320GB ).
AHCI Is enabled In BIOS.
Driver Used is : Intel 5 Series 6 PORT SATA AHCI Controller Version 10.1.0.1008.
Issue : Drive is found on windows BUT transfer rates is about 100-200 KB per second. And yes, it's not an error , KILOBYTES.
When using standard AHCI driver, the transfer rates are up to 50MB per second BUT it seems that i'm losing speed in my internal HDD.
I think that in order for windows to work as fast and accurate as possible , the intel driver is the best choice. But i cannot use my external drive in Esata mode with this driver.
My operating system is win7 x64.
Anybody to help ?
PS : With older driver version, 220.127.116.111, speed was OK but everytime i tried to copy something, win explorer hangs in the middle of the copy. In general, with this driver, system was unstable when connecting the esata drive.
