As we all know, mechanical hard disks commonly use ZDR technology, which divides several areas from the outermost to the innermost part of the disk. Most products are divided into 16 areas. The number of sectors per track on the outermost circle is exactly the innermost circle. Doubled, basically proportional to the change in sustained transmission rate.
Therefore, when the disk rotates, the greater the line speed in the outer ring, the more sectors are read, and the higher the transfer rate. Simply put, the partition is not the same, hard disk read and write speeds are not the same. , The general system by default the C drive is in the outer zone of the disk, which is the fastest read and write area.
When SSDs begin to reach millions of households and gradually have a tendency to replace HDDs, consumers are beginning to wonder again. Will SSDs be the same as HDDs, and the read and write speeds of different partitions will be affected by the position? In fact, the read/write mechanism of SSDs It is completely different from HDD, so don't worry too much about the same problems as HDD. But for SSDs, there is a rumor that SSDs should be less partitioned because more partitions mean more space is wasted and too many partitions will result in Partition misalignment has brought more impact on the use of SSD performance. So let's verify it today, whether the partition will affect SSD performance.
testing platform
We first divided the test hard disk into only one zone, and used a number of SSD read/write test software to perform read/write tests on it. Here we participated in the test from the disk drive 240GB solid state drive.
Then we divide the test hard disk into three zones, and each zone has a different capacity, perform the same SSD read/write test, and finally compare the results obtained, we can know whether the partition will affect the performance of the SSD. The single partition measured during the test is the performance of the D drive, and the performance of the E drive in the multi-partition case is proved to be a test performed under multiple partitions.
CrystalDiskMark test:
Single partition
Multiple partitions
Test Summary: In the CrystalDiskMark 6 test, random read and write performance and read/write performance of the same SSD in only one zone and multiple zones are not much different. However, this may also be a software problem. We will use it again. Test other software.
AS SSD Benchmark Test
Single partition
Multiple partitions
Test Summary: Using the AS SSD Benchmark to perform read and write performance tests on the solid state, the hard disk will have no difference in terms of continuous read/write performance or random read/write performance in the case of single partition and multiple partitions. Hard disk scores are even higher.
Anvil`s Storage Utilities Test
Single partition
Multiple partitions
Test Summary: In Anvil's Storage Utilities test, the performance of the two did not vary greatly, and the multi-partition case even got a little higher on the overall score.
After our test, the statement that multiple partitions will affect the performance of SSDs is obviously not reliable. Therefore, we do not need to fear that too many partitions of SSDs will affect performance. We can partition them according to actual needs and hard disk capacity. However, if SSDs are used, With multiple partitions, the 4K alignment of each partition is independent. Do not ignore the 4K alignment of non-system partitions.
In general, whether SSDs are partitioned is still a matter of habit, and everyone can do it according to their preferences.
