To compare the values of the mSATA SSD with the previously tested SSD benchmark values, we have installed the mSATA SSD to a commercially available SATA to mSATA adapter. The Delock 61881 converter SATA 22-PIN to mSATA full size costs approx. 15 EUR and can be ordered for example here.

Here you can see the additionally acquired adapter board, which connects the data lines of the SATA interface with the mSATA board and has a voltage regulator to offer the required voltage of 3.3V:
