With a Mac Pro RAID Card or Xserve RAID Card installed in your computer, you can use RAID Utility to turn your computer’s internal disks into storage volumes based on RAID (redundant array of independent disks) schemes that improve performance. Create a disk set using Disk Utility on Mac. You can create a Redundant Array of Independent Disks (RAID) set to optimize storage performance and increase reliability in case of a disk failure. You can also create a set that concatenates smaller disks to act as one larger disk. Apple Mac Pro RAID Controller Card 639-0108 A1228 A1247 for 2009-2012 Tower. 5 out of 5 stars (1) 1 product ratings - Apple Mac Pro RAID Controller Card 639-0108 A1228 A1247 for 2009-2012 Tower. 4 pre-owned from $25.00. Apple 820-2591-A Mac Pro Raid Card A1247. Mac Pro 2006 and 2007 have a SATA II 3.0 Gb/sec. (300 MB/sec.) controller. Throughput with my SSD RAID 0 is 800 MB/sec. Total via all devices plugged into the 4 controllers in the system. Most SSDs bench out at 240-250 MB/s for single SSDs on Mac Pro 1,1 or 2,1.
You can create a Redundant Array of Independent Disks (RAID) set to optimize storage performance and increase reliability in case of a disk failure. You can also create a set that concatenates smaller disks to act as one larger disk.
In the Disk Utility app on your Mac, choose File > RAID Assistant.
Select a set type:
Striped (RAID 0) set: A striped RAID set can speed up access to your data. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
Mirrored (RAID 1) set: Protect your data against hardware failure with a mirrored RAID set. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
Concatenated (JBOD) set: Increase storage space with a concatenated disk 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.
Select the checkboxes of the disks you want to include in the set.
For 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.
Enter a name for the RAID set in the RAID Name field.
Click the Format pop-up menu, then choose a volume format that you want for all the disks in the set. (See File system formats available in Disk Utility.)
Click the “Chunk size” pop-up menu, then choose a disk chunk size that you want used for all the disks.
When you create a striped set, chunks of data from the same file are distributed across the drives. Ideally, you want data distributed across drives evenly and at an optimum size so that it can be efficiently accessed. 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. With mirrored disk sets, choose a chunk size that matches the data you’re accessing. 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.
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.
If you have a Mac Pro with a Mac Pro RAID card, use RAID Utility. It uses the RAID card for better performance and to create more types of RAID sets.
