How many hard drives can I fit into one host? What should I pay attention to when expanding hardware

First of all, we have to look at whether your host is a dedicated server or whether you use your PC as a host.

Ordinary PCs generally have 2 IDE interfaces, IDE1 and IDE2 two interfaces, if the light area occupies one, there is another one, but there are 2 heads on our data line, if you set up the master and slave hard disk, you can identify 2 hard disks, in addition to the IDE line on the light area can also try to install a hard disk, theoretically yes, but I have not experimented.

As for what you asked, you should pay attention to those, if it is just the expansion of the hard disk, there should be nothing, mainly depends on the power of your computer's power supply, generally we require more than 300W, if it is low, it is easy to bring it up, as for others, such as the expansion of memory, you must pay attention to the brand and model.

Generally, it can be loaded with two!

Content and hard drives! It doesn't matter if the rest is true!

The ordinary main version can only be connected to 1, but it can be connected to an external hard disk, that is, a mobile hard disk.

It mainly depends on how many IDE slots you have on the board, the general optical drive occupies one, and the others can be used to expand the hard disk.

Currently I have 4 IDE slots on my computer, and I have 2 disks installed myself.

It mainly depends on how much hard drive space you need.

Ordinary motherboards only have 2 IDE interfaces, 2 IDE ports can be installed with 4 hard disks, but then you have no place to install a CD-ROM drive, if you are an optical drive, you can only install 3 hard disks, and you can set up a master-slave jumper.

Points to pay attention to in expansion include whether the motherboard supports the hardware to be expanded, whether the power supply is enough, whether the hardware compatibility is good, and heat dissipation.

A computer host can install 2 hard disks, how many hard disk interfaces on your computer can be installed as many hard disks, and the location of the computer optical drive can also be used to install hard disks, so there are many notebooks to remove the optical drive and replace it with a hard disk to install it.

The IDE interface on the motherboard can connect two hard disks (i.e., master disk and slave disk), and the motherboard has two IDE ports, i.e., IDE1 and IDE2, so theoretically, one PC can connect four hard drives.

If you use an adapter card, you can connect more drives. Finally, for the installation of multiple hard drives, it is a dual hard drive installation because the hard disk installation on IDE1 and IDE2 is exactly the same.

Before you start installing a dual hard drive, there are a few things that you need to consider first. The first is whether the space is enough, please install the second hard disk; Secondly, whether the power supply is sufficient. If the computer is running low on power, the drive head keeps resetting and the drive gets corrupted.

When installing a dual hard drive, keep the following in mind:

1. When adding or upgrading hard drives, try to use the same hard drive with the same brand first.

Because the compatibility of different brands of hard drives may occur on the same hard drive. The workaround is to put the new hard drive on the second hard drive. If you must use the same hard drive cable, change the primary drive of both hard drives according to the relationship.

Also, if you connect the newly added hard disk and optical drive** to a second hard drive, be aware of the primary device of the optical drive, etc., and the slave disk settings will not conflict with the newly added hard disk.

Otherwise, the motherboard may not be able to detect other hard drives or find issues with the original optical drive.

2. Pay attention to the problem of letter interlacing.

In the case of multiple partitions, the order in which the hard drive partitions are divided is somewhat strange: the computer still treats the main partition of the main hard drive as the C drive, and the main partition of the second hard drive as the D drive, and then the other in the first drive.

These partitions are sequentially separated from the E drive, then the other partitions of the second hard drive, and then the last drive letter of the first hard drive is converted in turn. After installing dual hard drives, it may cause system or some software abnormalities.

It is normal for a personal computer to install two hard disks, as long as the motherboard provides an interface to install a hard disk, the installation interface of the current personal computer is generally two or four hard disks, that is, if there is a motherboard with four interfaces, you can install up to four hard disks.

Home PCs are generally up to 4. However, the model capacity of the 4 hard disks must be the same.

Yes, but you need to set it up, and then it's easy to find the second disk.

Whether you can add a hard disk depends on whether there is a SATA interface on the motherboard (now home hard disks are SATA).

and whether there is still room for a hard drive in the main chassis.

For the installation of hard disks on old machines, first look at whether there is a place for the hard disk in the front of the case.

If you have more than one hard drive bay, you can simply place the hard disk. The chassis shown in the picture can directly install multiple hard drives.

If the chassis could only hold one hard drive. You can see if there is any extra optical drive bit, and then use the optical drive bit to transfer the hard disk bracket, so that the hard disk can be placed in the optical drive bit.

At the same time, a large hard disk bracket can also be added to the blank space under the original hard disk bay, and the height of the bracket is required to be just right to be placed inside. However, there is no side panel with screws on the side in this picture, so the additional hard drive bracket needs to be fixed in other ways.

If you encounter the situation of installing a lot of hard disks. For example, in the first image, there are 7 hard drive bays and 4 optical drive bays. It means that Wang Feng can install up to 11 hard disks.

However, the number of SATA ports on the main computer board is limited, and you can purchase a hard disk expansion card separately. A hard drive expansion card can have 2 or 4 SATA connectors. The hard disk expansion card itself needs to pay attention to whether it is a PCI interface or a PCI-E interface.

There is no effect between SSDs and HDDs. As long as there are enough SATA interfaces, it is fine.
