What are the benefits of HDD Group RAID In addition, I have two Seagate serial port 80G hard disks,

There should be no problem, the serial port is faster.

RAID5 is the best solution. RAID Classification & Overview:

RAID is the abbreviation of Redundant Array of Inexpensive Disk, which means cheap redundant disk array, which is the theoretical standard for the technical implementation of disk arrays, and its purpose is to reduce errors and improve the performance and reliability of the storage system. The commonly used levels of RAID are level, etc.

1. RAID 0 is the fastest and most efficient array type, but it does not support fault tolerance.

2. RAID 1 is suitable for arrays with high performance requirements and fault-tolerant functions. In addition, RAID 1 is the only option to support fault tolerance in environments with fewer than 2 disks.

3. RAID 3 is used to enhance data and accelerate data transmission for a single user on continuous long records.

4. RAID 5 is the best choice in multi-user environments with low performance requirements for data writing. However, it requires at least 3 and usually uses 5 disks to perform.

5. RAID 10 combines good reliability and high performance.

Plug in the hard disk, boot up and press the hotkey to enter the RAID control interface (there is a prompt when booting up, generally Ctrl+A, Ctrl+H, Ctrl+I, etc.). In the configuration interface, make the 3 hard disks into RAID 5, divide the logical drives (logical drives are hard disks in the eyes of the operating system), reboot the machine, and install the operating system (you may need to set the boot device in the BIOS first).

A few tips: 1. When your 3 hard disks are doing RAID, the data on them will be emptied;

If the block hard disk is RAID 5, the final capacity is the capacity of the smallest disk*2;

3. Most motherboards cannot use IDE hard disk group RAID;

4. If it is an Intel motherboard, you can consider using Intel Matrix RAID technology to build RAID, which is more flexible;

5. You can also consider using soft RAID (Windows and Linux have corresponding functions), and the way is also very flexible;

6. If the motherboard does not have an integrated RAID controller, you can purchase a RAID card to build RAID;

7. In the process of using RAID, once the RAID array alarms, the best solution is to buy a new hard disk immediately to replace the alarm hard disk, rather than to know and ask questions, remember to remember!!

First, the subject is different.

1. RAID0: Merge more than two hard disks into one, and the data is continuously split on each disk. Because the bandwidth is doubled, the read and write speed is doubled.

2. No RAID: There is only one hard disk, and the data is stored on the hard disk in order.

Second, the way is different.

1. RAID0: Parallel operation on data can make full use of the bandwidth of the bus and significantly improve the overall access performance of the disk.

2. Do not do RAID: Serial operation is used on the data, and the bandwidth of the bus cannot be fully utilized.

3. Different ways to request data.

1. RAID0: If the system has a data request, it can be executed by multiple disks in parallel, and each disk executes its own part of the data request.

2. Do not do RAID: The data is obtained by disk pointer addressing.

The difference between a single hard disk doing RAID0 and not doing RAID is: different storage, different security, and different reads.

First, the storage is different.

2. A single hard disk does not do RAID: A single hard disk does not do RAID and is separated from other hard disk data, and less data is stored.

Second, security is different.

1. Single hard disk do RAID0: A single hard disk does RAID0 because it shares data with other hard disks, once there is a virus in other hard disks, this hard disk will also be affected, and the security is low.

2. A single hard disk does not do RAID: A single hard disk does not do RAID because it does not share data with other hard disks, even if there is a virus in other hard disks, this hard disk will not be affected, and the security is high.

Third, the reading is different.

1. A single hard disk does RAID0: A single hard disk does RAID0 on the computer, and all RAID0 hard disks are regarded as a unified read entrance.

2. A single hard disk does not do RAID: A single hard disk does not do RAID on the computer, which is a single read entrance.

Indeed, in the early RAID card hanging disk, even if it was only used for a single disk, it was necessary to do RAID (that is, a single disk RAID0) to use, and now the new RAID has no similar problems.

There is no difference in performance between a single RAID 0 and a single disk on a common PC, only the performance difference between the RAID card and the PC SATA interface.

The data stored on the server can be read out by this hard disk made into RAID0 on the PC!
