If you’re confuse to choose between a 5400 RPM vs 7200 RPM hard drives, in this article, we’ll discuss the difference between the two drives and when you should get each one.
I know that 5400RPM is efficient and more reliable than 7200. But the same drive is slower or should be slower… With all discussion on the lastest Solid State Drives and the drive transfer speeds they offer. It is quite easy to check the time-honored, platter-based hard drive. But make sure that there is still no good option when it comes to storage than going with the older hard drive.
After the advances in tech, the platter-based hard drives are the feasible data storage devices. Also, it might be difficult to understand, today’s 5400RPM drives are very faster than 7200RPM drives from just a few years ago. Why? because their spin speed is not the single factor on platter-based hard drive performance. After the arrival of PMR, the areal density is increased or enhance, and head movement is quicker due to the distance to data points is shorter.
Rotation Speed (RPM)
As we know that the HDD is composed of parts such as read-write heads, platters, a motor spindle, etc. However, the platters are attached to the motor spindle in parallel and the platter’s storage surface is equipped with the magnetic head.
The magnetic heads move with the platter’s radial direction. They are coupled with the high rotation speed of the platters at many thousand revolutions per minute (RPM). So the magnetic heads can be located at a particular position on the platter for writing or reading data.
Therefore, in HDDs, the RPM is that of the motor spindle which stands for the max number of revolutions that the platters can complete within one minute.
Also, when the rotation speed increases, the hard disk becomes faster and can find files. Not just this but also the higher the transmission speed of the hard disk. So, the rotation speed determines the speed of the hard disk.
Difference: 5400 vs 7200 RPM
Well, the disks speed can be faster than 15,000 RPM. High-speed hard drives such as 10,000 RPM hard drives are used in many servers. But the ordinary hard drives RPM for home use is 5400 RPM or 7200 RPM. In this section, I will discuss 5400 vs 7200 RPM hard drives to you.
7200 RPM Hard Drives’ Pros
The first advantage of 7200 RPM hard drives’ is high performance. The more the hard drive ration speed, the quicker the hard disk. So, 7200 RPM hard drives are faster than 5400 RPM hard drives.
For a 7200 RPM hard drive, the time needed for each revolution is 60 × 1000 ÷ 7200 = 8.33 milliseconds. But if we talk about the average rotation latency time then it is 8.33 ÷ 2 = 4.17 milliseconds. So, the average rotation latency time of 5400 RPM hard drive is 60 × 1000 ÷ 5400 ÷ 2 = 5.56 milliseconds.
As we talk about the rotation speed, then 7200 RPM is a maximum of 15% faster than 5400 RPM hard drives.
However, the gap between the 5400 RPM and 7200 RPM hard drives is not significant in terms of ordered read and write capabilities. The thing that reflects the performance gap between both of them is the random write or read capabilities. However, it affects the speed of ‘read/write’ for fragmented programs or files startup speed.
Therefore, if you like to install the operating systems or execute programs on HDDs. Then you should select 7200 RPM hard drives. As it can make your operating systems or programs run faster.
5400 RPM Hard Drives’ Pros
If we talk about the advantages of 5400 RPM hard drives’ then it is low energy consumption, low noise, low heat production, and longer lifeline.
Higher rotation speed can reduce the average rotation latency time and the exact read and write time of the hard disk. Not just this but it also brings -ve effects like an increase in temperature, working noise, motor spindle wear, etc.
Similarly, if many other factors remain unchanged, then the increasing rotation speed means that the consumption of power of the motor will also enhance. However, it consumed more electricity per unit time, and the battery working time will be limited.
So, from this perspective, then hard drives 5400 RPM is superior to 7200 RPM hard drives. Also, if you use HDDs to recover data, then 5400 RPM hard drives are enough capable of that.
Note: Because of heat dissipation and portability requirements, notebooks use 5400 RPM hard drives. Desktops use 7200 RPM hard drives. Also, if your laptop has good cooling performance, you can then install a 7200 RPM hard drive on it.
What Do You Know About Areal Density?
Areal density is the total amount of data that can be wrapped onto each platter of the hard drive. So, the higher the density, the more data. When the hard drive is faster then the data is more compact. However, the faster the drive mechanisms can get from bit to bit to read and write data. Also, it can be expressed in Gigabits per square inch (Gb/in2). For example, the duty of the two people is to deliver newspapers. They both have the same amount of papers and on bicycles they doing their deliveries.
But one has a route that is rural with many farms between each house. The other is delivering a newspaper in an area where each house is built right next to each other. Who will complete delivery first? Of course, the second one.
Difference Perpendicular Magnetic Recording Or Longitudinal Recording?
All electronic data split ones or zeros. Switch on, or off. Saving that data long term begins with punch cards. Also, the card section either had a hole punched in it (highlighting a “zero”) or it didn’t (highlighting a “one”). Lots of cards were required to achieve the easiest of tasks. However, we’ve advanced through other procedures in which to save data – mainly using small magnetic particles lined up on some sort of media (whether be tape, cassette, drums, floppy disks, CDs, DVDs, etc.)
Suppose each piece of data is a tiny domino tile. One end is +ve and the other is -ve. It depends on the way the tile face determines that 0 or 1. For years, the manufacturers of hard drive used a longitudinal arrangement of dominos lined up all over the platters.
Now after the advanced technology, the hard drive manufacturers stand each of those dominoes on end – enabling for a higher density. If we take the example, it would be like marking every dominos on one end instead of the face of the tile. Stacking this way enables lots of dominoes to adjust to the table. This also decreases the distance from one data point to the other, which means a quicker drive.
CMR vs SMR
PMR HDD is also known as CMR (Conventional Magnetic Recording) HDD. It adopts the PMR technology, making the direction of magnetization data bit perpendicular to the platters so as to enhance the density of areal. In CMR (PMR), the write tracks are attached closely merge but don’t overlap.
The write or read functions of the HDD magnetic head are separated. However, the write magnetic head is usually greater than the read magnetic head. It is just due to the read operation that doesn’t need any changes to the magnetic medium while the write magnetic head applies a powerful magnetic field to flip the magnetic medium.
In PMR mode, the write head width checks the total number of tracks on the platters. So, if HDD suppliers want to enhance the density of magnetic recording, they will limit the size of the write head to the physical limit when it is possible.
However, because of physical limitations, the track width can only be decreased to some extent.
If you want to continuously increase the storage space per disk, SMR (Shingled Magnetic Recording) comes out. As it can be view as an extension of PMR technology. But besides CMR (conventional PMR), which does not let the tracks to overlap each other. Aslo, SMR writes the latest tracks that overlap part of the earlier written magnetic track. As it leaves the earlier track narrower and enabling for higher track density.
As the name suggests the read head can read data from the uncovered part of the track. But when you randomly write or overwrite data the writing process becomes slower. Since writing to one track can overwrite other tracks, and require them to be rewritten as well (because a portion of the earlier written magnetic track is overlapped).
However, if your hard drive is an SMR HDD, you can use it to archive files, but I advise you not to execute the program or system on it, or you can do other write operations on it.
