Mixing HDD brands in a RAID-6 array?

[MichaelSmith]

Hello,

I've got a RAID-6 array with ten Seagate 2TB NAS drives here. One of the drives started throwing medium errors after a reboot last night, so I'm going to replace it.
I can't find the Seagate 2TB NAS drives locally, only OEM from various vendors including Newegg. I *can* get 2TB Western Digital Red drives locally; how bad is it to mix brands of drives in an array? I've always done matched drives before.

Please help

I didn't find the right solution from the internet.
