I've checked under high performance and samsung high performance plans. I get the same performance results.

It might be a limitation on the Board BIOS then as a power management setting inherit to the board.
If the whole system is stressed that limit might be so it stays within the power requirement of the battery and psu setup.

Sorry can't offer more advice than that. Laptops do have some limits though usually you can change them.

The next best thing to do would be to test the SSD on another system if you have not already just to confirm it isn't the SSD.

Dude it's on a laptop, try to plug your SSD on your friend systems (PC), just to make sure that the SSD is fine....before you do some troubleshooting for your SSD. I'll do that if I were you.

I guess you are right. I checked my event viewer and i do have event id 37- the speed of the processor is being limited by system firmware. I think the power policy of the laptop mobo does this to conserve power. I've also asked lenovo tech support and they said they will get back with an answer. Thanks for your replies.

I will do that. Thanks for your suggestion.

FYI no one is immune from firmware updates. even my intel 530 series needed a firmware update to work properly with my mac.

I finally figured out what the problem was. I uninstalled the Intel Rapid Storage Technology driver and used the generic AHCI controller. The performance results have improved right away!


I did not expect any difference in everyday basic performance, but atleast now i know that the ssd and laptop are not defective.
Thanks everyone.smile.gif

Wondering why such a big difference? I thought Intel's rapid storage technology makes the drive performance better (unlike my case). I also see that 4K speeds have dropped a bit and the acc. times have slightly increased, notwithstanding the overall improved score. So, are acc. times dependant on 4K reads more than sequential reads?
Overall, which should i use for a better performance, the iaStorA (Intel RST) or storachi (Generic MS)?

What version of the Intel drivers were you using? I'm running 13.1.0.1058 from 5/2/2014 and I seem to not be having any performance issues on my older 840 EVO.

I used 13.0.2.1000 version dated as 8/12/2014 from the lenovo website. Looks like i'm using an older version. May be this is the version recommended for my mobo? Or should i try a newer one?
