Rugged RAID User Manual 27
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.
