What RAID to choose?

Are you looking to find out what the usable capacity will be in RAID 1 versus RAID 60? Platinum Data Recovery experts in raid data recovery has developed a free RAID Calculator to help you quickly find out what the usable capacity is for a given configuration. This Raid Disk Space Utilization Calculator can help you determine the chances for data loss in the given number of disks in different RAID levels. The purpose of this tool is to estimate your RAID reliability.

You can use this tool to calculate RAID usable capacity by entering the number of disks used, the size in TB (terabytes) of each drive, and the RAID level. After entering the specifications, click the Calculate Usable RAID Capacity button. The result will show capacity statistics to tell you the usable capacity of your RAID array and the unavailable space. You can also find out the maximum read and write performance relative to using a single disk. This tool can provide approximate theoretical figures to help users compare different RAID levels. The purpose of this tool is to understand the risk associated with disk failure that is commonly used in RAID configurations.

RAID Calculator to Compare RAID Types

Redundant Array of Independent Disks (RAID) combines several disks into one data storage device to achieve faster performance and increased fault tolerance. The components of a RAID system interact in complex ways which result in varying usable space, service speed, and fault tolerance from one configuration to the next. It is noteworthy that even if an array is fault-tolerant, it is crucial to ensure the reliability of a single disk.

There are different RAID levels and each configuration has specific benefits and drawbacks. For instance, RAID 0 offers better read/write speeds by using striped sets to record fragmented data across several disks. However, due to the lack of data redundancy, disk failure can result in data loss. RAID 1, on the other hand, offers protection against hardware/drive failure. One of the most popular types is RAID 5 that offers fast write speeds while protecting data by distributing parity across several drives. Likewise, RAID 6 also provides protection with an extra parity block that ensures stability even if two drives fail. The more complex array configurations like RAID 10, RAID 50, and RAID 60 are also reliable because they keep working when two or more disks fail. Our tool can help you prevent data loss scenarios when several disks fail simultaneously.


Compare Different RAID Configurations

Platinum Data Recovery has developed this RAID calculator so that you can find out what the usable capacity is for a given configuration. This will help you understand the chances of data loss given a number of disks in different RAID levels. This tool can also be used to get an idea about RAID reliability. You can determine which RAID level is the most reliable given a number of drives. This allows you to make an informed choice about your next RAID array configuration.

If this is your first time configuring a RAID array, you might be confused about which RAID level to choose. The right RAID level for you depends on your application. Each RAID level has its pros and cons, so consider different configurations to determine the best one for your application. You need to consider the commonly used RAID configurations and compares them based on storage size, RAID performance, fault tolerance, and cost. This tool can be used to find the usable capacity in RAID configuration. You should also find out how many disks need to fail in order to cause data loss. Remember, no matter which RAID configuration you choose, always backup your data to prevent data loss.
