This week in ISM3004 we learned about advanced storage in computer systems. One particular system we learned about was the RAID1. I think this particular system is best for high security systems that contain sensitive information. The attributes of the RAID1 that make it the best for this scenario are if there is a single drive failure the RAID1 will not lose any data and continue working at full speed. This could be very important for a bank or similar type of business that uses software.
However, there are many types of RAID systems and each one caters to a particular type of system. For instance, the RAID5 is very common in network servers. I would imagine RAID5 is popular among large companies with many different computers that pull from one server or memory drive.
For businesses that are looking to store large amounts of data with low costs, the HSM enterprise storage is probably the best option. The net result is usually more total capacity and you spend less money on high performance disk systems.
