I want to buy a laptop, is it good to have a hard disk of 160G and 7200?

Rotationlspeed is the rotation speed of the motor spindle in the hard disk, that is, the maximum number of revolutions that the hard disk platter can complete in one minute. The higher the rpm value, the faster the internal transfer rate, the shorter the access time, and the better the overall performance of the hard drive.

In terms of heat dissipation, the temperature is still controlled at about 41 degrees Celsius under 7200 rpm high-speed operation, which is the lowest temperature of all tested hard disks, which is very rare. This will mean that the temperature of the laptop with this hard drive can be controlled at a lower heat state, giving people a more comfortable operating experience.

So if there is no big difference in heat, choose 7200.

The 7200 rpm one is much more expensive than the 5400 rpm one.

I recommend choosing a 250g with a large storage capacity of 5400 rpm, in fact, the heat of the hard disk will not be very large.

I've been using it for so many years.

If you have enough funds, it is recommended to buy a speed 7200 with a storage capacity of 250g, and if you want to be affordable, it is still 250g and 5400 rpm.

7200rpm,Now the heat dissipation of this book is good,5400The actual use is much slower,If you are worried about heat dissipation and external cooling equipment,It's not expensive,Dozens of yuan,Moreover, the hard disk is not the main source of heat。

Choosing a laptop hard drive is also crucial. Whether working or playing games, most of the stuttering, freezing, and slow response are closely related to the hard drive. Choosing a laptop and a good hard drive is important. What hard drive should I choose? Let's share it together!

Common notebook hard drives on the market are divided into mechanical hard drives and solid state drives. Among them, mechanical hard disks are divided into 5400 rpm and 7200 rpm, and now they are basically 7200 rpm. There are many types of SSDs:

SATA interface and NVME interface. The main difference is in the read and write speed - mechanical HDD read and write 100 m s, SSD SATA interface read and write about 500 m s, ordinary interface read and write about 3000 m s, good can reach 7000 m s, you may not have a concept. Intuitive example with boot time:

The boot time of the HDD is 30s, and the boot time of the SSD is within 10s. There are pros and cons to everything. Megastool SSDs have fast read and write speeds, but they are not as stable as HDDs for storing files.

Personally, I think that the combination of notebook hard disk is mechanical hard disk + solid state hard disk.

For example, there are many hard disks with commonly used interfaces on the market, and only a few are hybrid hard disks. Maybe you will see PCIe and PCIe in the process of picking, where PCIe's read and write speed is about 3000MS, PCIe is about 7000MS, and PCIe is definitely more solid-state efficient for people who often deal with large files. But for the average consumer, the two experiences aren't much different.

2. If you have high requirements for computer speed, but the capacity of the hard disk is not very high, it is recommended to choose a 750G7200 hard disk, after all, the hard disk runs faster, but the capacity is relatively small and careful.

3. If you have high requirements for speed family denier, and the capacity of the hard disk is also high, it is recommended to use a 1TB5400 to mechanical hard disk + 120G solid state drive.

The performance indicators of the hard disk are:

1. Spindle speed: The spindle speed of the hard disk is one of the determining factors that determine the internal data transmission rate of the hard disk, which largely determines the speed of the hard disk and is also an important symbol to distinguish the grade of the hard disk.

3. Warmth and awareness of the surface of the hard disk: This indicator indicates that the temperature generated by the hard disk when it is working makes the temperature of the sealed shell of the hard disk rise.

5. Cache: This indicator refers to the high-speed memory inside the hard disk. The current cache of the hard drive is 64MB or even larger.

7. Maximum internal data transmission rate: The name of this indicator is also called continuous data transmission rate, and the unit is mb s. It refers to the maximum data transfer rate from the head to the hard disk cache, which generally depends on the platter speed of the hard disk and the platter line density (referring to the amount of data on the same track).

8. Continuous Trouble-Free Time (MTBF): This indicator refers to the maximum time from the beginning of operation of the hard disk to the failure, and the unit is hours. Generally, the MTBF of hard disks is at least 30,000 hours.

This indicator is not provided in general product advertisements or common technical feature sheets, and can be specifically checked online to the specific company that produces the hard drive** when needed.

9. External data transfer rate: This indicator is also known as burst data transfer rate, which refers to the rate at which data is read from the hard disk buffer. In advertisements or hard disk feature tables, the data interface rate is often used as a substitute in mb s.

You've only given the spindle speed, and you've got to consider other performance metrics, so there's no definite answer to your question. If you want to make a comparison, give the specific model of laptop hard drive and desktop hard drive, so that you can compare.

It must be 7200 rpm, although it is only 750g capacity, but think about it, how many g can you use? Although the previous one has 1TB, it is only 5400 rpm, which is a little slower. And if you want to watch movies, play games, save data, etc., then the speed must be fast.

So let's choose the 7200 rpm. It's fast and the capacity is enough for you! Hope it helps!

2. If you have high requirements for computer speed, but the capacity of the hard disk is not very high, it is recommended to choose a 750G7200 hard disk, after all, the hard disk runs faster, but the capacity is relatively small.

3. If you have high requirements for speed and hard disk capacity, it is recommended to use a 1TB5400 rpm mechanical hard disk + 120G solid state drive.

At the same time, under the premise of ordinary hard disk instead of SSD solid state drive, it is recommended to choose 7200 rpm, because the memory size is only a difference of more than 200G between 1024 and 750, and the read and write speed has risen by a big notch.

The heat dissipation at 5400 rpm is better, but the heat dissipation at 7200 rpm is faster, but the heat dissipation is not as good as the heat dissipation at 5400, and each has its own benefits.
