    I know p157sm-a is the mainstream for now.. but p157sm is cheaper.
    I buy a Hasee K680C in China(it is the P157sm model), the sticker in the motherboard is 3.6A, I think it is the lastest board in this model. It is unlucky I also meet the problem of the secomd msata drop to sata II . The ssd I use is Toshiba THNSNF256GMCS, 256GB. I use two of them to create a RAID 0. The ssd on the port 4 will drop to SATA II(3Gb/s) sometime, it seems it is completely random. The port 5 is OK for SATA III(6Gb/s).
    I have asked the reseller to change 3 laptops of this model. ALL of them have the same problem.
    I know I could sell it and buy another 15.6 gaming laptop, but MSI GT60 has a worse cooling and the weaker performance for the same GTX780M. really sad.
    I dont know whether the new P157sm-A handled this problem or the problem still is here.. But P157sm-A is selled with GTX 8xx card in China, so the cost performance is really low..

    It seems a lot of people in china doesn't concern or know this issue. Maybe they are just interesting in VGA performance.. I found there are only two persons in a most popular chinese laptop barebone forum to discuss this issue.

    I had this problem on my P151SM bought last October in Beijing (Terrans Force branded). I found changing the "Link Power Management" option in "Intel Rapid Storage Technology" program to "Disable" cured it. This was on Windows 8. I haven't had a problem with 8.1 yet.

    Thanks for the reply.
    But I checked IRST software, and found LPM option is already set in "Disable".
    So maybe this isn't the reason to cause the msata down to sata II.

    I have Prema modded BIOS, maybe that has stopped my problem. It was a long time ago now since the problem occurred for me so I can't give any other advice, but I would say that can be fixed. GL.

    Yes, the problem was resolved with a board revision just before SM-A and then the fix carried over into the SM-A model. You can look into a firmware update (BIOS + EC), but not sure whether that was originally the problem or if it was hardware related.
