The differences between disk arrays and storage servers are: 1. Different properties. Disk array is a method, while storage servers are physical devices; 2. Different purposes. Storage servers are used to provide services for storing data, while storage servers are used to provide data storage services. RAID technology is used to increase data access speed and achieve redundant protection of data; 3. Different compositions. Disk arrays place data on multiple hard drives, while storage servers are usually independent units.

What are the differences between disk arrays and storage servers?
1. Different nature:
Disk array is a method, and storage server is a physical device. Redundant Array of Independent Disks (RAID) is a method of storing the same data in different places on multiple hard drives. Storage servers are designed for specific purposes and therefore are configured differently. It might be a server with a little extra storage, or it might be a server with a lot of storage.
2. Different uses:
The storage server is used to provide services for storing data. RAID technology is used to increase data access speed and achieve redundant protection of data.
3. Different compositions:
By placing data on multiple hard drives, the disk array allows input and output operations to overlap in a balanced manner, improving performance. Because multiple hard drives increase mean time between failures (MTBF), storing redundant data also increases fault tolerance.
Storage servers are usually independent units. Sometimes they are designed as 4U rack-mounted. Alternatively, two boxes can be used to form a storage unit with a nearby server.
