Synbios Posted January 18, 2011 Share Posted January 18, 2011 I would say it is not normal to have write speed faster than read speed, but your numbers are all not that bad and within advertised speeds so there is nothing to be concerned about imo.

This guy also have same ssd,according to his results, always read speed is higher than write speed. http://forum.corsair.com/v3/showthread.php?t=92103 Also other users have same results...

Synbios Posted January 18, 2011 Share Posted January 18, 2011 In his scenario however his write speed was well below specifications, also he was using a laptop. Your read speed is only slightly less than the write speed and it is very close to advertised specification. Link to comment Share on other sites More sharing options...

I searced about G31, ICH7 doesn't support ahci,so i was wrong enabling ahci. I think this is caused the slow reading speed.That's my fault. Also I used my ssd with laptop .(Lenovo G550, T6600 2.1 Ghz with 3 gb ram) It has ahci support and I did secure erase,fresh install,activating ahci mode with regedit and bios and tested with atto. Result is same with sapox's first results. http://forum.corsair.com/v3/showthread.php?t=92103 He suggested changing balanced mode to performance mode,that is working.I tried but nothing has changed.

Synbios Posted January 19, 2011 Share Posted January 19, 2011 The Lenovo's use power saving features and their benchmarks are sometimes low even after changing the power mode to performance. There is a limitation on the chipset/BIOS. I'm sorry but this is not the Corsair drive at fault. Link to comment Share on other sites More sharing options...
kenzi Posted February 2, 2011 Author Share Posted February 2, 2011 Thank You @Synbios I tested with p67 based Motherboard and sandy bridge cpu.I think it seems great. Link to comment Share on other sites More sharing options...

Yes those are perfect benchmarks for this drive, this shows that often times the controller/motherboard can be at fault when the drive seems to be slower than advertised.
