Hello all,

We are using solid state disks on the 6501, both as mSATA and normal SATA. These are the models that we have tried:
        MUSHKIN MKNSSDAT60GB-V (mSATA)
        MUSHKIN MKNSSDCR60GB-7 (SATA)
        Intel 320 40GB (SATA)

Read performance is great, we see 150MB/s, but write performance is limited to 20MB/s regardless of which SSD or interface type that we use.

This is evident in all of the kernels we have tried, including the stock CentOS 6.6 2.6.32-504.el6.x86_64 and 3.14.x.

Is 20MB/s really the maximum write performance of the SATA bus? If not, what might be the issue?
