1.1.4.1 Selecting Drives
The Drobo 5C supports standard 3.5” SATA hard disk drives (HDDs). For HDDs, these
drives can be from any manufacturer and with any capacity.
In summary, here are the recommended number and type of drives you can use with
your Drobo 5C. Note that you need at least two drives in the drive bays to ensure your
data is protected in the event of drive failure.
● 2 to 5 HDDs in the main drive bays - enables you to maximize capacity
For a performance comparison of these options, see the image below.
Important Notes:
The Drobo 5C is not compatible with IDE, SCSI, PATA or SAS drives.
The Drobo 5C supports migrating entire disk packs from a Drobo Gen 3,
preserving its data. For more information, and to ensure a safe and successful
migration of the drives, carefully follow the instructions in Migrating a Disk Pack
from Another Drobo Device.
Warning:
Any pre-existing data on the drives will be erased when inserted into the Drobo
5C.
