RAID 0 is the fastest RAID mode since it writes data across all of the array’s hard drives. Further, the
capacities of each disk are added together for optimal data storage. However, RAID 0 lacks a very important
feature: data protection. If one hard drive fails, all data is lost. A recommended option is RAID 5, which
offers:
Performance that can approach RAID 0.
Approximately 75% of the storage capacity of all the hard drives in the RAID configuration.
Data protection in case a single hard drive fails.
RAID 1
RAID 1 provides enhanced data security since all data is written to each disk in the array. If a single disk fails,
data remains available on the other disk in the array. However, due to the time it takes to write data multiple
times, performance is reduced. Additionally, RAID 1 reduces disk capacity by 50% since each bit of data is
stored on both disks in the array.
