When data is written to the disk the RAID 5 reserves some space for parity information, which allows the RAID 5 to recover lost data. This increases performance while providing a level of redundancy. In a RAID Level 5 the data is distributed across all the hard disk drives. This scheme can be recommended for small servers with two disks.īest for: Reliability, performance and capacity This scheme paired with a backup solution can work well to provide high uptime. If the data is critical and reliability is paramount RAID 1 is a strong candidate. As the RAID 1 scheme mirrors the data onto another HDD or set of disks, only half of the total storage space is available to the operating system.Has comparable read and write speed to that of a single HDD.This gives the administrator time to replace the failed HDD without losing data In the case of a single HDD drive failure the data will still be available to the operating system. This level offers increased resilience in the case of a single HDD failure the data can still be accessed from the mirror HDD or set. In a RAID Level 1 scheme the same data is written to more than one hard disk drive. This scheme paired with a backup solution can work well in situations such as image editing, video editing and gaming. If the data is non-critical, performance is key and downtime isn't a concern RAID 0 is a strong candidate. If a single disk fails within this type of scheme then all the data is lost, so make sure you have a back up RAID 0 does not provide any fault tolerance.if you are have two 1TB drives in a RAID 0 scheme the system will combine those two drives so that you store 2TB worth of data
Allows all of the disks storage capacity to be used, e.g.This level offers superior performance as this allows the system to split the data, allowing it to read and write across multiple HDDs simultaneously. In a RAID Level 0 scheme, data files are spread across all participating hard disk drive (HDDs). To give you a better idea of the RAID levels concept I will describe the most popular RAID levels along with their minimum requirements and the pros and cons of each.
#BEST RAID SOFTWARE FOR MAC MAC OS X#
Many operating systems include Software RAID functionality as standard, such as Windows Server (2003 and above), MAC OS X and Linux. The hardware RAID offers better performance but tends to cost more than the software alternative.Ī software RAID does not require the use of specialised hardware. The RAID controller can be on a separate card that connects to the computer or it can be included on the computer's motherboard. There are two possible RAID approaches: Hardware RAID and Software RAID.Ī hardware RAID employs the use of specialised hardware called a RAID controller which connects to and manages the hard disk drives. It's worth mentioning that there is a minimum number of disks required to use each RAID Level. To achieve this RAID uses "schemes" or, to be more precise, RAID levels, with each RAID level providing a different balance of these three goals. RAID systems can be configured to meet the needs of your business with these goals in mind. The RAID system basically takes 2 or more hard disk drives (HDD) and gets them to work in parallel. Redundant Array of Independent (or Inexpensive, depending on who you ask) Disks (RAID) is a technology employed by many companies to increase the performance and reliability of their data storage. Use RAID to increase the performance and reliability of your data storage
