There are …To configure a software RAID, right-click on one of the drives you’d like to include in the array and select the option to create a new Striped (RAID 0), Mirrored (RAID 1), or Spanned (JBOD ...RAID is a redundant array of independent disks. This storage mechanism makes it possible to recover data even in the event of a disk failure. There are several array levels (RAID 0, RAID 1, etc.) depending on how the data is distributed across the disks. This article will focus on the OpenZFS - specific RAID-Z.2 Answers. Sorted by: 15. Add the number of hard drives minus 1. Either all the drives have to be the same size, or if you use different sizes, the RAID will treat all the drives the same as it would the smaller one. 10 1TB hard drives equal 9TB of storage. 9 1TB drives and one 500GB drives is 4.5TB of storage (each 1TB is treated as a 500GB)

There are … • RAID-5 — eliminates the dedicated parity drive by writing parity with the data across all drives in the array. Consequently, the single-write restriction and some performance degradation of RAID-1 through RAID-4 are eliminated. If a drive fails, the controller can rebuild the data from the parity and data on the remaining drives. Parting with memory-laden objects is not easy—but it's probably time to let a few things go.

RAID, or "Redundant Array of Inexpensive Disks," is the process of combining multiple hard drives or SSDs in parallel as one logical volume, making the array more resistant against drive failures. There are many kinds of RAID, and we'll discuss which one you should choose. RAID 10 is a very common RAID level, especially with high capacity drives where a single disk failure makes a second disk failure more likely before the RAID array is rebuilt. During recovery, the performance degradation is much lower than its RAID 5 counterpart as it only has to read from one drive to reconstruct the data.RAID 10 array converts all information into data blocks and writes it on multiple arrays.
