  SSDs can give a huge performance benefit to MD trajectory processing.
I wrote a paper in 2011 that describes this in some detail, where I
got VMD to read trajectories at several gigabytes per second using
multiple SSDs in a RAID:

The performance does depend somewhat on the trajectory file format,
and my paper describes those issues in some detail also.
