Does hard disk partition need to be an integer?

Will not slow down or damage the hard disk.

It doesn't matter if you divide it up or down.

Actually, I didn't want to answer, but people who play games don't care because you said you wanted four RAID0 arrays or put photos, but put photos ... I know photos are very important for photography, and RAID0 is the most dangerous mode. Although it is fast, all your four disks will be lost as long as one data is broken, and the data is not so easy to recover after RAID0 group.

If you really want to pursue speed, you can consider other RAID arrays, such as RAID 10. The data is quite safe. If a disk is broken, it will be replaced by a new one. Automatic recovery speed is the same as RAID0, but the capacity is reduced. Of course, there are other compromises, such as RAID5. Think for yourself. Is capacity important or safety important?

As for the partition, whatever the array is, it will be the same as the disk in the system after assembly. If you partition as before, WIN7 will have nothing to say, and the system disk capacity will be 40G. Of course, it doesn't matter if it's big. Your hard drive is not small anyway. If you like throwing things at the desktop, you can consider moving the desktop to another disk.

My personal habit is that if the system disk is enough, the rest will be divided into two large partitions, one of which will store my documents, desktop and some important files, and the other will store the rest and lost games. Personally, it's better to get a few folders (hehe, operating partitions under WIN7 requires administrator permissions and no folders, so it's sometimes not so convenient for you to use them as folders). If you think it has reference value, you can try it. This is purely a matter of personal habit. How many discs are divided basically has no effect on the speed. How to conduct a group raid? In fact, the motherboard instructions are generally written, which most people should understand, and the steps of each brand motherboard are different, so it is not easy to make it clear.
