Yes you can use different manufacture drives in the MD3600f to create a new raid array or replace a failed disk. What you need to make sure of is that the drives have a Dell Part# on them otherwise the drives will not be seen by the MD3600f. If you get drives with the same model# but not a Dell part# on them using our support matrix then your drives will not be seen by the MD3600f. ftp.dell.com/.../powervault-md3600f_Concept%20Guide_en-us.pdf
