This article mainly introduces the distinction between imbricate hard disk and vertical hard disk, the article is very detailed, has a certain reference value, interested friends must read it!

Distinguishing method: if the hard disk capacity is less than 2TB, if the storage is 256MB, then it is a stacked hard disk; for a vertical hard disk, the cache below 2TB is 64G. In addition, you can also use some test software in your computer to test the random read and write performance of the hard disk. Generally speaking, the hard disk with poor performance is the stacked hard disk, while the vertical hard disk has better performance.

How to tell the difference between vertical hard drives?

For a normal PMR vertical hard disk, 64G cache is below 2T, and 128G cache may be above 2T. When erasing data, the write head of the vertical hard disk is wide, while the read head is narrow, so in fact, all the places on this track are not used when writing, and other data of the nearby track will not be affected. When reading, you only need to read the middle area. So relatively speaking, the security is relatively high.

How to tell the difference between a stacked hard disk?

The full name of stacked hard disk is "corrugated stacked hard disk". When purchasing a hard disk, the product capacity of consumer-grade mechanical hard disk is less than 2TB. If there is 256MB in the cache, it is almost certain to be a stacked hard disk. After getting the hard disk, you can also use some hard disk test software to test its random read and write performance. If the general performance is much worse than the product of the same capacity, it should also be a stacked disk.

The vertical hard disk has better performance, faster random reading and writing speed and long service life.

The difference between a vertical hard drive and a stacked hard disk:

The main advantage of the vertical type is that when erasing the data, it will not affect other data in the nearby track, so it is relatively safer, and when fragmenting the data, it will not cause the hard disk to be overburdened and significantly slow down. in addition, because the imbricate erase and overwrite data operation requires the head to write data twice, the relative head life will be affected.

The stacked hard disk can achieve 2T per disc, so the number of discs in large capacity can be reduced, the overall thickness of the hard disk and vibration heating can be better controlled, and the reduction of the number of discs can also reduce the failure rate to a certain extent. In addition, if the data is written once as a warehouse disk and then read, the experience of the imbricate disk is not much different from that of the vertical type.
