![]() ![]() L Minimum number of drives: 4 l Data protection: Up to two disk failures.Ī RAID 6 with hot spare array is the same as a RAID 5 with hot spare array with an additional parity block. It uses block-level striping with two parity blocks distributed across all member disks. The total disk space available is the total number of disks minus two.Ī RAID 6 array is the same as a RAID 5 array with an additional parity block. When you replace the failed hard disk, the new hard disk is used as the new hot spare. If a hard disk fails, within a minute of the failure, the hot spare is substituted for the failed drive, integrating it into the RAID array, and rebuilding the RAID’s data. ![]() If a drive fails, it can be replaced and the FortiAnalyzer unit will restore the data on the new disk by using reference information from the parity volume.Ī RAID 5 with hot spare array uses one of the hard disks as a hot spare (a stand-by disk for the RAID). With RAID 5, one disk can fail without the loss of data. RAID 5 performance is typically better with reading than with writing, although performance is degraded when one disk has failed or is missing. For example, with four hard disks, the total capacity available is actually the total for three hard disks. The total disk space is the total number of disks in the array, minus one disk for parity storage. The parity block is staggered for each stripe. Similar to RAID 0, the FortiAnalyzer unit writes information evenly across all drives but additional parity blocks are written on the same stripes. The total disk space available is the total number of disks minus two.Ī RAID 5 array employs striping with a parity check. If a hard disk fails, within a minute of the failure the hot spare is substituted for the failed drive, integrating it into the RAID array and rebuilding the RAID’s data. This is the simplest RAID storage design with the highest disk overhead.Ī RAID 1 with hot spare array uses one of the hard disks as a hot spare (a stand-by disk for the RAID). A rebuild is not required in the event of a drive failure. One write or two reads are possible per mirrored pair. Should any of the hard disks fail, there are backup hard disks available. This provides redundant data storage with no single point of failure. The total disk space available is that of only one hard disk, as the others are solely used for mirroring. The FortiAnalyzer unit writes information to one hard disk, and writes a copy (a mirror image) of all information to all other hard disks. l Minimum number of drives: 2Ī RAID 1 array is also referred to as mirroring. ![]() This RAID level is beneficial because it provides better performance, since the FortiAnalyzer unit can distribute disk writing across multiple disks. If any single drive fails, the data on that drive cannot be recovered. ![]() The total space available is that of all the disks in the RAID array. The FortiAnalyzer unit writes information evenly across all hard disks. All data will be lost.Ī RAID 0 array is also referred to as striping. If any of the drives fails, the entire set of drives is unusable until the faulty drive is replaced. There is very little performance change when using this RAID format. The total space available in this option is the capacity of all disks used. Supported RAID levelsįortiAnalyzer units with multiple hard drives can support the following RAID levels:Ī Linear RAID array combines all hard disks into one large virtual disk. For FortiAnalyzer devices containing multiple hard disks, you can configure the RAID array for capacity, performance, and/or availability. We’ve redesigned the SoftRAID driver to process TRIM commands even more efficiently and now supports continuous data transfers over 12GB/s enabling you to take advantage on breakthrough technologies like the OWC Accelsior 8M2.RAID helps to divide data storage over multiple disks, providing increased data reliability. Right now you can share RAID 0/1 HFS+ volumes seamlessly between computers bringing a whole new level of computing harmony. SoftRAID licenses are now universal enabling you to use both the Mac and PC versions of SoftRAID. Easily activate and deactivate your license to move to a new computer or add additional discounted seats to make sharing your RAID volumes easier. SoftRAID features an all-new license system making it easier to manage your licenses and provide better security. SoftRAID 6.2.1 work with both Intel and Apple silicon Macs and adds compatibility for macOS 12. Our Mac software team has been hard at work adding new features for SoftRAID as well as adding support for the Apple new OS – macOS 12 Monterey. ![]()
