We are using MD1400 and 1420 enclosures to test hard drives. The reason was to take advantage of the 12G speed. It looks like only SAS drives will be recognized by these systems. It makes some sense since SATA are only 6GB but wanted to see if possible to use SATA drives in these.
They only support SAS, however there are Nearline SAS drives that should work and have higher capacity. http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/DellStorage_MD1400_MD1420_082114.pdf?newtab=true
