It protects your data so that, if one drive fails, you won’t lose everything. RedundancyĪnother benefit of using multiple drives in coordination is that you can configure your system to duplicate data across drives. As you can imagine, larger capacities come with a larger price tag. This means RAID systems can come in higher capacities than are possible with single-drive solutions. However, enclosures can include up to eight or more drives. That means a RAID needs at least two paired drives to work. RAIDs provide these benefits through the use of multiple storage drives configured to work together. They can offer massive storage capacity, data protection through redundancy and blazing fast read and write speeds - though not necessarily all at once. They usually look like a tower or rack-mounted system. RAID stands for Redundant Array of Independent Disks. When you have lots of data to store and protect, and you need to access that data often, a RAID is going to be your best option. Then, we’ll look at two important factors that need to be considered when purchasing storage of any type. It uses the RAID card for better performance and to create more types of RAID sets.In this guide, you’ll find a list of the best storage drives on the market today, hand-picked by the Videomaker editors.

If you have a Mac Pro with a Mac Pro RAID card, use RAID Utility. If you are creating a mirrored RAID set, select the “Automatically rebuild” checkbox to allow the set to be automatically rebuilt when member disks are reconnected. For example, when working with video files, your Mac is accessing large chunks of data, whereas when using a database of many small records, your disks may be accessing smaller chunks of information. With mirrored disk sets, choose a chunk size that matches the data you’re accessing. If you want high data throughput from your set, choose a smaller chunk size so that data is spread across the drives and one drive can be accessing data while another is seeking the next chunk.
Ideally, you want data distributed across drives evenly and at an optimum size so that it can be efficiently accessed. When you create a striped set, chunks of data from the same file are distributed across the drives.
(See File system formats available in Disk Utility.)Ĭlick the “Chunk size” pop-up menu, then choose a disk chunk size that you want used for all the disks. Select the checkboxes of the disks you want to include in the set.įor each disk, click the pop-up menu in the Role column and choose “RAID slice” or “Spare” to designate the disk as a standard member or spare in the set, then click Next.Įnter a name for the RAID set in the RAID Name field.Ĭlick the Format pop-up menu, then choose a volume format that you want for all the disks in the set. If you need one large disk, but you have several smaller disks, you can create a concatenated disk set to use as one large disk. You can’t create a RAID set on your startup disk you must first start up your computer from another disk.Ĭoncatenated (JBOD) set: Increase storage space with a concatenated disk set. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly. Mirrored (RAID 1) set: Protect your data against hardware failure with a mirrored RAID set.
You can’t create a RAID set on your startup disk you must first start up your computer from another disk. Striped (RAID 0) set: A striped RAID set can speed up access to your data. In the Disk Utility app on your Mac, choose File > RAID Assistant.
