Can RAID 1 have 4 drives?
RAID 1 consists of at least two drives, so four drives are acceptable. The data distribution mechanism here is mirroring. This type of array has excellent performance, where the write and read speed is high. However, you can only use 50 percent of independent disks for data storage.
What RAID can I use with 4 drives?
RAID 10 (Mirroring + Striping)\n\n RAID 10 requires at least 4 drives and is a combination of RAID 1 (mirroring) and RAID 0 (striping). This will get you both increased speed and redundancy. This is often the recommended RAID level if you're looking for speed, but still need redundancy.
How many disks can be in a RAID 1?
Must hard drives in a RAID array be identical? No. It is perfectly valid to use hard drives from different manufacturers, model numbers, sizes, and rotational speed (spindle speed or RPM).
How many drives are in a RAID 1 array?
RAID 1 consists of at least two drives, so four drives are acceptable. The data distribution mechanism here is mirroring. This type of array has excellent performance, where the write and read speed is high. However, you can only use 50 percent of independent disks for data storage.
What is the best raid with four drives?
The result is the perfect combination of excellent data protection and high performance. It should be noted that the most optimal RAID with four drives is RAID 10. The disk segment size is the size of the smallest disk in the array.
Is it possible to use a root drive as a RAID1?
The first 50 GB of each drive was used as a raid1 for the OS, and the rest of each disk was for user data. So it has a 4 or 12-way raid1 for the root drive, and a small swap file on this drive. So yes its totally possible and workable, and used in production by commercial solutions.
