Why is the hard drive write slow, the SSD write speed is too slow

The rotational speed of the hard drive can be viewed with software such as Everest, as can HD Tune.

My laptop hard drive is similar to the landlord's, but the real internal transfer speed has to be tested with the software mentioned above, and I copy the file directly in Windows and then feel that the speed is inaccurate.

It is recommended that you defragment your disk and stop using lossless partitioning software such as PQMAGIC.

Try it on the back port, it may also be caused by your mobile hard disk problem, it is recommended to change to a separate USB flash drive or mobile hard disk (not a brand) to try, you can determine whether it is a compatibility problem, or a problem with your hard disk.

The old hard disk is generally the hard disk cache is too small, and the hard disk speed is not fast, resulting in poor performance.

Maybe it's been a long time since I've cleaned it up.

Look it up with Hard Disk Sentinel.

Defragment. Junk files.

The key is to see if and when your speed is slower.

If the old hard disk is compared with the current one, it generally feels slow, and it is impossible to speed up in this case.

PS: Check if the U port is high-speed. If not, then the U port should be replaced with a high-speed one.

Scan the hard disk, it should be too many bad sectors, after scanning out, if it doesn't work, change it.

The U-port is used in the back, don't use the U-port on the front panel, the U-port on the front panel is very slow, if the U-port is not enough, use the mouse, keyboard and the like to plug in the front panel.

If you don't want to, you can clear the temporary files and junk in the system.

I've had this problem too.

1 Clean up the debris.

2 Clean up the registry.

There's a lot of garbage in it that affects your reading and writing.

There are bad sectors. And no less. I guess it's going to be replaced with a new one. Complete.

5400 rpm? Otherwise, there will be bad ways.

The reasons for this are as follows:

1. The performance of the SSD is degraded due to the energy-saving mode turned on on the motherboard

Usually, the motherboard's energy-saving function is enabled, and the CPU frequency will be reduced, which will also lead to a decrease in the performance of the SSD, because the CPU frequency will be reduced by 10% when saving energy, and it will be 10% slower when sending instructions, so the theoretical SSD performance will be reduced by 10% during the test, so if you want to give full play to the best performance of the SSD, please do not turn on the energy-saving mode on the motherboard.

2. Misconnection to the third-party SATA3 interface affects performance

Now the new motherboard supports SATA interface, and the use of SATA interface is also very important for SSD, if the motherboard we choose does not support SATA connection, then it will have a greater impact on the performance of SSD. On the other hand, the test results of the third-party SATA3 interface solution are almost completely inferior to the results of the native SATA3, especially in the startingApplications speed, which is a full 20MB difference. As a result, the score dropped significantly, and the use of a third-party SATA3 chip solution greatly slowed down the random speed, resulting in a sharp drop in performance.
