Getting into the semantics of a "backup," by definition, RAID is a backup. A backup is just storing a second copy of your ...

If you're using a RAID level with parity, like RAID 4, 5, or 6, you're introducing more writes to your array. In the context of RAID, parity means that the array can be rebuilt if a drive fails.

RAID 0 does not mirror or store any parity data though, so the loss of a single drive will take down the entire array. Configuring SSDs in RAID 0 can result in some truly jaw-dropping transfer speeds.

The PCI cards accomplish this feat by using RAID Level 0, which alternates the data stream between two or more drives. Since both drives can write data at the same time, a two-drive array has the ...

We used the --assume-clean parameter when creating our RAID arrays in order to avoid overwriting every block of the array, and we used -E lazy_itable_init=0,lazy_journal_init=0 when creating the ...

If the existing SATA RAID array is a bootable configuration with an operating system, then a fresh install of Windows 10 will be required; A motherboard BIOS update is required to support NVMe RAID.

The only absolute requirement for matching drive specs in a RAID 10 array is that the drives must be of the same architecture, e.g., all SAS or SATA. Mixing and matching drives of differing ...

Big storage companies stopped recommending RAID 5 a couple of years ago. But I still see small 4-drive arrays touting RAID 5 for home and small office use.

Changing from a RAID 0-array boot drive to a single-drive boot should be easy, I thought, but the operation can be more complicated than may you anticipate. Here's what I learned from the experience.

The acronym RAID stands for Redundant Array of Independent Disks. It's a technology that emerged in the late 1980s, which greatly improved the way we employ storage drives.
