Hi OutlawPiper,Dell Inspiron 15z comes with Intel RST technology, wherein it is configured by one mSATA drive and one normal mechanical hard drive. The Operating system is installed on the hard drive and mSATA hard drive is used for caching purpose, so that frequently used programs or instructions are virtually stored on mSATA partition as SSD are faster than the normal hard drive. You will feel the computer is fast.You can install the operating system on the 32 GB mSATA drive but over the time the system will slow down because of space constraint, basically operating system would need 15GB space and later you will be installing third party applications and games which would reduce the space. It’s recommended to use 32GB and 64GB mSATA drives as a caching device. If you upgrade the mSATA drive to 128GB or 256GB mSATA drives then you can use them has a regular hard drive.
Hi, I just received my Inspiron 15z with 32GB mSATA and 500GB HDD, and I was disappointed to find that Windows 8 is installed on the 500GB (presumably 5400 RPM) HDD.  For performance sake, I expected that the OS would be installed on the mSATA drive. I'm not sure the best way to fix this with the Recovery Media, as I've never done this before.  I don't want to run into Windows activation issues, but I want to do a clean installation using the mSATA drive as my OS drive. I don't really care about the recovery partition, since it's apparently configured incorrectly (in my opinion).  I just want the OS on the mSATA drive. How best do I fix this? Thanks in advance.
