We can see that there is a large gap between the two running results. Therefore, we recommend that you take the average value for multiple running times.
The results of these two tests are very simple. When you test disk performance professionally, you not only need to know the read/write performance, the size of read/write data (4 k/16 k/32 k) should also be distinguished, and sequential read/write or random read/write
quite mature, the combination of SCSI hard disks on interfaces always keeps up with the times. Furthermore, hard disks are very important devices for computers and are indispensable. In fact, all hard disks are similar, but because of the different SCSI specifications, there are still some differences in the appearance of some of them.
