In this test we have created three file folder copy scenarios and we are copying them between two folders within the drive, recording the time taken for the file transfer to be completed. Our first folder is filled with 870 picture files totaling 1GB, the second folder is filled with 550 MP3 files totaling 2GB and the third folder is home to a single 4.5GB ISO file.
Crucial's m4 mSATA drive performed extremely well in this test, considering that the advertised maximum write speed of the drive is "just" 260MB/s, nearly half the speed of most drives it is being compared to. Nevertheless, the synchronous NAND flash and the Marvell controller appear to be giving the Crucial m4 an edge, allowing the drive to compete head-to-head with other popular high performance SSDs.
In our second real world test we are recording the time taken for our OS to fully boot from when we pressed the power on button and the start up times of two very popular and heavy professional applications, the Autodesk AutoCAD 2012 and the Mathworks Matlab. These tests are excellent examples of how an actual system would start and work under real-life circumstances.
The performance of the Crucial m4 mSATA drive did not appear to be considerably better than that of any other high performance SSD currently available, yet it is not worse either. Boot and software start-up times are almost identical between the compared drives, with the differences being just a few fractions of a second.
