Virtualized arrays and advances in RAID technology have benefited corporate customers with faster, more secure RAID storage solutions. But it's not so easy to judge a RAID array by it's number anymore. Other factors, beyond the designation of RAID 0, 1, 5, 10, etc., have dramatic impacts on a RAID servers speed.
The data in modern RAID drives is spread across many more drives, and some of it is stored virtually using extremely advanced storage virtualization technology.
If you're looking to upgrade to a RAID array, or upgrade your existing RAID server, the arrangement of the disk drives will have a small effect on performance. But here are a few additional factors you should consider to assess the speed and performance of a new array:
- Power of the CPU in the array
- Capacity of the array's cache
- Capacity of the disks in the array
- Reviews from other users with storage needs similar to yours regarding real-world performance of the RAID drive
