Function introduction
In the CrystalDiskMark interface, you can select the number of tests, the test file size and the test object. Click the buttons in the lower row to perform a single file read and write test or multiple small file read and write tests of 512kb or 4kb. In fact, this kind of software is of no use to the hard disk. I keep it in the computer to test the speed of the USB flash drive. Friends in need can try the reading and writing speed of their own USB flash drive. According to what is said online:
The reading speed of USB1.1 is generally 630KB, and the writing speed is generally 520KB; the reading speed of USB2.0 is generally 1.5MB, and the writing speed is generally 1.0MB.
Speaking of USB flash drives, when purchasing, it is best to choose a model that does not heat up after being plugged into a computer for 10 minutes. Nowadays, some USB flash drives start to heat up after being plugged into a computer for 5 minutes. The quality is really worrying. It is not suitable to use it on a computer. If you hold it for a long time, it will get hot. I am using a 32MB black box USB flash drive from OMG that I bought 6 years ago. It barely heats up after being plugged into the computer for half a day. I haven’t lost data in so many years. I like it very much, but the capacity is a bit small. Now I want to buy a bigger one. The quality is not as good as that of that time, hey (it seems to be similar to the situation with TVs).
How to use
The specific usage methods are as follows:
Seq: Continuously perform read and write hard disk detection (1024K bytes)
512K: Randomly perform read and write hard disk detection (512K bytes)
4K: Randomly perform read and write hard disk detection (4K bytes)
4K QD32: Random read and write detection for NCQ and AHCI modes (4K bytes, queue depth 32)
2. Click "All" to detect all items.
3. The hard disk read and write speed is being tested.
4. The test is completed, and each data is shown in the figure below.
5. If you need to keep the test data, click "Edit Copy" to copy the test data.
6. Paste the detected data in Word and save the data.
