One reason I decided to work with the folks at DCIG to collect data for their Small Business Storage Array Buyers’ Guide was to learn more about the various products in the space. One difference I noted in these small arrays, which usually hold 4 to 8 drives, is their use of hard disk drive carriers or sleds. There are pros and cons to both approaches, but I was pleased to see that all arrays so far include everything needed to install a drive.
