beised Posted January 17, 2012 Share Posted January 17, 2012 I'm a bite disapointed with a Force GT 3 60GB. My Mother board (Asus m2n68-AM looks to have a 3gb Sata controller. I've tryied two alingment, trim, stop temps to run at ssd, noatime, etc. But, the Read speed never goes beyond 145mb/s. Frankly, My Samsung 502hj shows a better top read speed at 150mb/s and about the same average as Gt3 ~140mb/s. To be honest Hdparm results are the opposite of what I expect to see. /dev/sda: GT3 Timing cached reads: 1868 MB in 2.00 seconds = 934.06 MB/sec Timing buffered disk reads: 374 MB in 3.01 seconds = 124.30 MB/sec /dev/sdb: Samsung 500Gb Timing cached reads: 1960 MB in 2.00 seconds = 980.66 MB/sec Timing buffered disk reads: 432 MB in 3.01 seconds = 143.59 MB/sec The only possible mistake should be at aling procedure. So, if anyone know the correct numbers PLEASE HELP!!!!!!!!!!!! Below the GT3 numbers: Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders, total 117231408 sectors Units = setores of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Thanks in advance Eduardo Link to comment Share on other sites More sharing options...
Toasted Posted January 17, 2012 Share Posted January 17, 2012 Your motherboard uses an Nvidia Chipset. The chipset runs the SSD on SATA I speeds. To get a higher read/write speed, You will need to upgrade your motherboard to an AMD chipset. Link to comment Share on other sites More sharing options...

Goolging around I also get the information about turning the Raid5 on the performance goes up. BTW, Anyone knows if there's a way to force AHCI mode in Bios of the Asus m2n68-AM se ??? I couldn't found this at the Bios menu! Thanks! Eduardo Link to comment Share on other sites More sharing options...
madnisman Posted January 18, 2012 Share Posted January 18, 2012 I'm not sure if this will work for you, but you can try to set the SATA controller to RAID in BIOS, but do not create a RAID array. Single drives connected to a RAID controller will work in AHCI mode. Link to comment Share on other sites More sharing options...
