It depends on what kind of files you transfer. Try to transfer an old file, one of those where you got 200mb/s.

maybe they are getting slower as the used space increases as drives are faster on the outside of the platter than on the inside... how much space have you used?

Because of their locations on the platter(s). Platters are circular and spin at a fixed speed, but that does mean more data passes under the head on the edge than in the centre.

Have you tested your drives with HDTune? The Blue line is the sequential speed.

When nearly empty this drive can provide 150MB/sec file copies. But as it fills up that drops, eventually hitting just ~60MB/sec.
