What is a RAID enclosure?

What is a RAID enclosure?

In other words, the RAID enclosure is a backup for hardware failure of a single drive. It does not protect against loss of more than one drive at the same time, a defective RAID controller, data deletion by accident or lost data due to a virus or data corruption.

Can you do RAID with external hard drives?

While you often can combine multiple external hard drives, there can be problems doing so. The other is to rip the drives out of their cases and shove them into a dedicated RAID enclosure or, if you’d like even more flexibility, a NAS (Network Attached Storage) device.

What does RAID mean for hard drives?

redundant array of independent disks
RAID stands for “redundant array of independent disks,” which is a way of storing data on multiple drives. There are a number of RAID levels, each of which offers different advantages. However, there are also some disadvantages to RAID, so it’s important to understand what happens when you copy data to a RAID array.

Why RAID is not a backup?

RAID Is Not Backup If a file is deleted or overwritten the RAID array cannot be used to retrieve it. When a file is deleted it is deleted from all the drives. When a file is overwritten it is overwritten on all the drives. Therefor a RAID array is not a backup solution.

What is raid5?

RAID 5 is a redundant array of independent disks configuration that uses disk striping with parity. It has more usable storage than RAID 1 and RAID 10 configurations, and provides performance equivalent to RAID 0. RAID 5 groups have a minimum of three hard disk drives (HDDs) and no maximum.

Should I get a NAS or a RAID?

If you are looking to connect multiple workstations to have access to the same data, a NAS is the best option. If you want to connect directly to your workstation to add additional storage or improve performance and security, a RAID array is the way to go.

Are NAS drives good for RAID?

NAS systems have an extra level of redundancy and security with RAID arrays. NAS lets you share large amounts of data easily, cost-effectively, and efficiently. The growing demand for NAS systems is due to several important factors, just add more storage without upgrading or altogether replacing existing servers.
