The problem with considering a RAID as your backup is that it doesn’t help you with file deletion, corruption by applications, operating system or viruses. RAID levels 2, 3, and 4 are not commonly used anymore. NTFS or HFS+) is recognized by the operating system, you will always be able to access your data.Best Raid Storage For Home Use. This means that you can move the drive from one computer to the other and assuming that the file system (e.g. The RAID is independent of the computer and the operating system.Even when using a RAID mode with redundancy (e.g. Preventing data lossJust because a product supports RAID doesn't mean the data is automatically safe. The RAID is dependent on the operating system and the data cannot be accessed from another system. For direct attached storage drives without RAID controller like the AKiTiO Thunder2 Quad and the AKiTiO Thunder2 Quad Mini, the RAID can be created by the operating system on the computer (e.g. For network drives like the MyCloud series, the RAID is created by the embedded Linux system.
![]() Same RAID controller, same power supply). Buying the same RAID enclosure for the second backup unit has the additional benefit that it can act as a backup for the hardware too (e.g. If you currently don't have another backup location and there is not enough space to keep the original data on your computer, consider buying a second RAID enclosure and another set of drives at the same time. Natural disaster or computer virus).Preparing enough storage space may be expensive up front when you need to buy additional drives but if your data is valuable, it is well worth the investment. Doing so makes it possible to easily and quickly recover your data even if you accidentally delete files, the data on that drive gets corrupted, the RAID controller fails or something else happens to your hardware and hard drives (e.g. This could mean that you keep the original data on your computer or make a second backup somewhere else. However, even then, it's important to make sure that the settings are identical and it's best to create a backup of all the data in a different location first, before moving the drives.For software RAID, the data can be accessed on other computers that are running the same operating system (e.g. The exception to this rule is when both products are based on the same RAID controller and the same firmware version. It's not possible to move the drives to another product without re-formatting the drives. Recovering and accessing data on a RAID arrayFor hardware RAID, the data can only be accessed when the drives are installed in the original product where the RAID was originally created. When you setup a new RAID or change the RAID mode, all existing data is lost! The exception to the rule is Non-RAID but even then, it's better to have a backup than lose data in case something goes wrong during the setup. RAID 0 - Disk striping is used where speed is the primary objective. Move all the data from the backup location back to the newly created RAID.Depending on the RAID controller and the amount of drives, you can select between different RAID modes to setup the disks according to your own requirements. Set your preferred RAID mode and format the drives. Backup all the data from the old drives in a different location. Expanding the storage capacity for an existing RAIDWhenever you change something on an existing RAID, be that installing larger drives or adding additional drives, it's necessary to create a new RAID system. For network drives like the MyCloud series, the disks should be installed inside a product that is based on the same firmware and the drives will have to be mounted manually. Sdr software for macThey are presented to the system as independent logical volumes. Non-RAID - No RAID is created and the disks can be accessed seperately. The exact definition of these terms depends on each model but following is a general description. RAID 10 - Disk mirroring with striping is used for redundancy in case of a single disk failure.Some additional terms that are used for AKiTiO's products include Non-RAID, JBOD, SPAN and BIG. RAID 5 - Disk striping with parity is a good compromise for performance, redundancy and storage capacity. ![]() MAKE SURE THE CORRECT DISK HAS BEEN SELECTED BEFORE YOU EXECUTE THE COMMAND! Type clean to clear the existing partition(s). As an example, to select Disk 3, type select disk 3. Select the external disk. Select from the available disks (1) and then click Add (2) to add the disks to the striped volume. The New Striped Volume Wizard appears. In this example, we will create a Striped Volume. Striped Volume, Spanned Volume, Mirrored Volume). Right-click a segment of free-space on the disk that you would like to include in the new RAID and select your preferred RAID mode (e.g. Click Yes to convert the disks and create the striped volume.This RAID cannot be accessed on other systems like Windows. If the disks are basic disks, you'll be warned that this operation will convert them to dynamic disks. Click Finish on the summary page to create the volume. Enter a name for the new volume (1) and click Next (2) to continue. You can also mount the volume on an empty NTFS folder on an existing volume. The default is to assign the next available drive letter to the new volume. Best Raid Storage 2016 Mac OS X 10In this example, we will create a Striped RAID Set. Striped RAID Set, Mirrored RAID Set, Concatenated Disk Set) and click Create (3) to create the RAID. Enter a name for your new RAID (1), select your preferred RAID type (2) from the list of available RAID modes (e.g. Select the RAID tab (1) and drag the drives (2/3) that you would like to add to the RAID onto the blank field in the RAID section. You can find this program under Applications > Utilities > Disk Utility. If you use Mac OS X 10.11 (El Capitan), you can still access your RAID set but you can no longer manage it through the disk utility. ![]() Repeat the previous step with the remaining two drives and drag them onto the second mirror set. Select two of the drives to be added and drag them onto the first mirror set. Click the plus button a third time (1) and name the RAID set but this time set the RAID type to Striped RAID Set (2). At this time, your new RAID set should also appear on your desktop. Click Create to build your RAID 10 system. Repeat the previous step with the second mirror. (2), enable the setting to Automatically rebuild RAID mirror sets (3) and click OK (4). Select the first mirror (1), click on Options. When done properly, each mirror will be indented from the striped set. RAID sets that were created on other systems can still be accessed. The only option is to use the Terminal and the diskutil command or purchase and install a 3rd party software like SoftRAID. Please be aware that the rebuild process can take quite a long time.With Mac OS X El Capitan, the disk utility can no longer be used to create and manage RAID sets. To do so, select the degraded mirror from the list, drag and drop the new drive into the degraded mirror and click Rebuild to start the process. If a drive fails and must be replaced, you will have to manually rebuild the mirrored RAID set. Once the drive becomes reconnected, the disk utility will automatically rebuild the disconnected drive.
