RAID hard disk capacity online calculator

Category: Web

Enter your data below
Array layout
Physical disk size (leave some fields blank if you plan to have fewer than five hard disks) Disk 1 GB
Disk 2 GB
Disk 3 GB
Disk 4 GB
Disk 5 GB
Result:
The capacity of the entire array
Fault Tolerance - Maximum expected number of simultaneous disk failures
Maintain the space needed for fault - tolerant information.
Relaxation - Due to the uneven size of the hard disk space loss; unable to use hardware implementation; can be combined into a software implementation, a separate array.
Estimation of transmission speed . Speed is relative to the speed of a single disk. Reading speed
Recording speed

Explanatory note

The write speed of a RAID5 depends on the implementation of the controller. Therefore, an estimate of the write speed of RAID5 is not provided.

Settings for RAID1 arrays involving more than two disks are allowed, but rarely used. Additional backups, disks provide additional fault-tolerant storage space at the cost.

RAID 10 capacity, half of single disk failures and double failures (based on the allocation of failed hard disks).


Comment The write speed of a RAID 5 depends on the implementation of the controller. Therefore, an estimate of the write speed of RAID 5 is not provided. The setting of a RAID1 (mirror) array involving more than two disks is allowed, but is rarely used. With additional backups, the disk provides extra fault-tolerant storage space. RAID10 capacity, half of a single disk failure and double failure (according to the allocation of a failed hard disk).
