Is it ok to mix old 2tb WD20EARS (parity) and new WD20EZRX (data)


Recommended Posts

I have an old Unraid version 4.6 where the parity drive is a 2tb WD20EARS and the data drives are also WD20EARS? Unfortunately, the last drive I added (which is actually model WD20EADS) has shown 500+ errors during the monthly parity run. The drive is marked as failed and disabled (DISK_DSBL).

 

Would it be ok to swap it with the WD20EZRX model even though it's a sata III drive and the parity is the much older sata II WD20EARS?

 

Thanks.
