RAID Reconstructor: 321Soft Data Recovery is the best choice for getting your data back, now includes a powerful RAID Reconstructor. You can also use this option to reconstruct broken RAID systems or lost RAID for recovering data on Mac. 321Soft Mac Data Recvery. Feb 16, 2012 A RAID array appears to the operating system to be a single logical drive, regardless of how many individual drives are part of the RAID array. Both hard disks and SSDs can be used, and while it's advised that matching drives are used in a single array for best performance, it's not strictly required.
- MacDrive 10 Pro gives you the power of Mac RAID on your Windows PC. With MacDrive 10 Pro, you can access Apple formatted RAID disks as well as RAID sets created with SoftRAID. You can also securely delete files and folders from your disk and easily create ISO images and mount sparse images.
- I have been using RAID on Macs and PCs since 1999, and I have done it in software and 7-8 different kinds cards on various OSes. I will tell you two reasons why I won't use software RAID anymore: first, if a drive has an issue and doesn't mount as expected, it will break the RAID volume, and correcting the issue takes more time and is prone to mistakes; secondly, RAID on software uses.
RAID, Redundant Array of Independent/Inexpensive Disks, is actually what it says. In English, a RAID set is a group of multiple separate disks, working together as a team. You can set up a RAID array on your MacBook. RAID can

You need at least two additional hard drives on your system besides the start-up disk, which you shouldn’t use in a RAID set.
To set up a RAID array in Mac OS X, follow these steps:
-
From the RAID tab of Disk Utility, click and drag the disks from the list at the left to the Disk box at the right.
-
Click the RAID Type pop-up menu to specify the type of RAID that you need.
-
Striped RAID Set: Choosing this can speed up your hard drive performance by splitting data between multiple disks.
-
Concatenated RAID Set: Choosing this allows several volumes (or even multiple disks) to appear as one volume within Lion.
-
Mirrored RAID Set: Choosing this increases the reliability of your storage by creating a mirror backup of that data across multiple disks.
-
-
Click in the RAID Set Name field and type the name for your RAID set.
-
From the Volume Format pop-up menu, choose a format for the volumes.Always use Mac OS Extended or Mac OS Extended (Journaled) from the Volume Format list unless you have a specific reason to use the MS-DOS File System (for compatibility with PCs running Windows). Journaling helps reduce the amount of disk fragmentation and also helps speed up your hard drive’s performance.

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.
-
Click Create.

Click Done.

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.
