All RAID arrays consist of at least two separate hard disk drives, and can sometimes be as many as five drives.
The high-performance cache and non-blocking interconnect schemes used in RAID arrays are also designed for applications with a lot of IOPS, and are not designed for high-bandwidth applications like backup.
The controller uses the full capacity of all disk drives when drives of different sizes are mixed in a RAID array, allowing system integrators to upgrade their customers' arrays with higher-capacity drives without wasting space.
Therefore, there are some limitations to the performance you can achieve using ATA drives in a RAID array.
Each method protects your data even if an entire RAID array fails.
With additional configuration flexibility using iSCSI targets, system builders can now partition NAS server and RAID array functions to better meet costumer needs and specifications.
The RAID array is designed for data center environments requiring Fibre Channel connectivity, performance, capacity, and scalability.
With the introduction of higher capacity drives and more drives per RAID array comes longer rebuild times and a longer window of vulnerability to rebuild failures and second drive failures.
Trying to defragment a drive that has multiple partitions or a RAID array doesn't make much sense, either.
With the additional configuration flexibility using iSCSI targets, system builders can now partition NAS server and RAID array functions to better meet costumer needs and specifications.
Will the addition of one more device, especially a high performance RAID array, push the load limit over the edge?
Let's take as an example a RAID array of four physical disks.
