C: onto other disks. It offers no boost in performance or redundancy and is a holdover from the days when smaller disks had to be chained to handle large amounts of data.
RAID 0 Striping : This setup increases hard-drive performance by splitting, or striping , data across two drives. By leveraging two data busses, data can be read and written more quickly. Unfortunately, RAID 0 provides no data protection—in fact, it actually increases the chances of data loss since the failure of either drive in the array results in the loss of the data stored on both drives.
RAID 0 setups are standard on high-end gaming PCs and graphic design workstations, and provide a measurable, albeit modest performance boost for hard-disk-intensive programs.
Since each drive is an exact duplicate of the other, you can continue working if one fails. RAID 5 Distributed Parity : Though you get both faster disk performance and data protection from this setup, it requires a minimum of three hard drives.
When one of the drives in a RAID 5 array fails, the data content of that failed drive is reconstructed using the parity bits on the surviving drives and written to a new, replacement drive. The array is still usable in the meantime. Otherwise, back up your important data. Best practice is to have three copies of your data: the original, a backup, and a backup of the backup, preferably offsite. Transferring an existing operating system is tricky, and with older versions of Windows, sometimes impossible.
What type depends on the flavor of Windows:. Windows RAID offers several advantages. You can mirror individual partitions, including partitions from different drives onto a single drive. Windows RAID is actually quite fast. Check your PC or motherboard documentation to find out if your motherboard supports RAID and if so, which levels , and for specific installation instructions. Adaptec , Promise and other vendors offer a wide selection of pricier, but more capable RAID adapters with onboard cache and advanced features.
Prepare your new system and ensure that you have written down or printed out the instructions if you do not have a notebook or tablet at hand.
I like to do my clean install with no other drives present. If you have other drives present, the possibility of other drives being set by default as the boot disc is likely.
Therefore you need to ensure the primary boot is set to the RAID volume. From here, a modern OS like Windows 8 will support your RAID array without further drivers, however older OS' will require additional drivers installed as it comes to search for drives to install to. HOME Articles crosshair-motherboards. Articles: Crosshair Motherboards Guides Motherboards. What kinds of RAID are there? RAID This technique has striping but no redundancy of data.
Drives are typically added in multiples of two. RAID This type is also known as disk mirroring and consists of at least two drives that duplicate the storage of data.
There is no striping. Read performance is improved since either disk can be read at the same time, meaning if one disk is busy the other is accessed.
Write performance is the same as for single disk storage. RAID-1 provides the best performance and some fault-tolerance in a multi-user system, although for a single user it's unlikely to see as much benefit.
One of the biggest merits of RAID 0 is that it greatly improves the performance and throughput of a hard drive. However, the biggest demerit is that RAID 0 provides no fault tolerance and parity information redundancy. That means you will lose all the data on the entire array once any disk fails and the whole system will be affected. You can create a RAID 0 array by using multiple disks with different sizes. According to the above information, you may find some key features of RAID 0.
To help you understand more clearly, here we summarize them as follows:. RAID 1 is known as a mirrored volume that also requires 2 or more disks. It contains a copy of the data on the disks. This configuration owns high data security because it provides fault tolerance and redundancy.
That means you still can restore the original data by using the mirrored disk. When creating a RAID 1 array, you need to make sure the array is as big as the smallest disk.
Since the data is mirrored on all disks of the array, this array can still work normally as long as one disk is operational. There are several key features that can help you identify the RAID 1 array more easily.
For that:. Are you tangled in choosing which SanDisk memory card? Get the answer from the post. In this part, we will discuss the RAID 0 vs 1 from the aspects of performance, reliability, data organization, and storage capacity.
This array was primarily designed to optimize the desktop applications that require high performance and reliability such as computer gaming. With the RAID 1 array, the random read performance is better than a single disk. Here MiniTool Partition Wizard is what you need.
It is a trusted disk benchmark tool that can help you test the performance of various disks easily. This tool has helped lots of users to make a comparison about disk performance such as as mSATA vs M. It can not only help you measure disk performance but do many powerful works.
