You can mix and match drive capacities and manufacturers. But often times, the type of drive you select can have a big impact on the performance of the Drobo due to the manufacture standards and how it functions with either NAS, DAS or SAN units.

Currently, we do not recommend using the following drives in Drobo:
- All SMR drives are incompatible and not recommended for use with Drobo
- If you are not performing a Migration (moving drives from one Drobo to another), and you have hard drive(s) with existing data on them, and you wish to use these drives into Drobo, you first need to copy the data off of these drives or else the data will be erased when you insert these drives into Drobo.
- While the Drobo Mini utilizes small form factor 2.5" drives the rest of the Drobo products use the large form factor 3.5" drives. This guide will focus on the 3.5" drive and SSD technologies to help you select the right drives for your application, allowing you to balance acquisition cost and performance requirements versus capacity requirements.
