Neither of these drives are particularly quiet (WD Green and Red drives are much quieter), but unless you have a RE and Black drive side-by-side in a quiet environment, you are The elements of a RAID may be either individual drives or arrays themselves. Safety first! Since many drive failures are due to mechanical issues (which are more likely on older drives), this violates the assumptions of independent, identical rate of failure amongst drives; failures are in navigate here
Such configurations include the following: Linux MD RAID 10 provides a general RAID driver that in its "near" layout defaults to a standard RAID1 with two drives, and a standard RAID1+0 Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. SED (Self-Encrypting Drive) – With a motherboard that supports this technology, SED allows the drive to be encrypted using the AES 256 bit encryption engine. ACM Computing Surveys. 26: 145–185.

It writes, or mirrors, data to multiple disks, so you've got multiple hard drives that are exactly the same. Since you're only using a single disk for parity, which has to be written to every time you write data, you can still only have one write operation going on at
