SAFE (RAID 1): RAID 1 provides data protection since all data is written to each hard drive at the same time. In
the event of a single hard drive failure, data remains available on the other hard drive. Due to the time it takes
to write the data twice, performance is reduced when compared to RAID 0. RAID 1 is a good choice when safety
is more important than speed. However, RAID 1 also reduces the available drive space by 50% due to the need
to write every bit of data to each hard drive.
JBOD: Hard drives are independent in a JBOD configuration. You can write data to one hard drive without
affecting the other hard drive. An advantage to this configuration is the availability of 100% of the hard drives'
total storage capacity. However, it does not offer redundancy and all data on a single hard drive is lost if it fails.
