Disapointed


beised

Recommended Posts

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

Your motherboard uses an Nvidia Chipset. The chipset runs the SSD on SATA I speeds.

 

Thanks!

 

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
