RAID 10 — combining mirroring and striping The software to perform the RAID-functionality and control the drives can either be located on a separate controller card a hardware RAID controller or it can simply be a driver.
This means that those disks do not use a specific RAID level and acts as stand-alone disks. This is often done for drives that contain swap files or spooling data.
Below is an overview of the most popular RAID levels: This performance can be enhanced further by using multiple controllers, ideally one controller per disk. Advantages RAID 0 offers great performance, both in read and write operations. There is no overhead caused by parity controls. All storage capacity is used, there is no overhead.
The technology is easy to implement.
Disadvantages RAID 0 is not fault-tolerant. If one drive fails, all data in the RAID 0 array are lost. It should not be used for mission-critical systems.
If you want to use RAID 0 purely to combine the storage capacity of twee drives in a single volume, consider mounting one drive in the folder path of the other drive.
This is supported in Linux, OS X as well as Windows and has the advantage that a single drive failure has no impact on the data of the second disk or SSD drive. RAID level 1 — Mirroring Data are stored twice by writing them to both the data drive or set of data drives and a mirror drive or set of drives.
If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continues operation. You need at least 2 drives for a RAID 1 array. Advantages RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single drive.
In case a drive fails, data do not have to be rebuild, they just have to be copied to the replacement drive. RAID 1 is a very simple technology. Disadvantages The main disadvantage is that the effective storage capacity is only half of the total drive capacity because all data get written twice.
Software RAID 1 solutions do not always allow a hot swap of a failed drive. That means the failed drive can only be replaced after powering down the computer it is attached to. For servers that are used simultaneously by many people, this may not be acceptable. Such systems typically use hardware controllers that do support hot swapping.
Ideal use RAID-1 is ideal for mission critical storage, for instance for accounting systems. It is also suitable for small servers in which only two data drives will be used.
It requires at least 3 drives but can work with up to Data blocks are striped across the drives and on one drive a parity checksum of all the block data is written.
The parity data are not written to a fixed drive, they are spread across all drives, as the drawing below shows. Using the parity data, the computer can recalculate the data of one of the other data blocks, should those data no longer be available."Read, Write & Type is an excellent example of the very best in computer applications to provide support for children learning to read.
The program not only incorporates the most important principles of beginning reading instruction, but it has also brought them together in a package that is very engaging for children. Segment 0 has read/execute protection, and segment 1 has read/write protection. The memory system is a demand-paged virtual memory system with virtual addresses that have a 4-bit page .

The routine takes four arguments: mm is a pointer to the mm structure of the address space in which the fault occurred, vma is a pointer to the vm-area that covers the page that is being accessed, addr is the virtual address that caused the fault, and access type is an integer indicating the type of access (read, write, or execute).
