Difference between speeds

How is the speed of backups determined? Figure 1 has a drive that has some better data and some less but is much faster at backing up and uploading them.

What's the reason for this?

You ask a question, but do not provide all the data. You expect us to guess if it's the same system, what models of drive it is, whether they used the same version of the test software and a thousand other things.

 

It's like putting two Of slots on the tire of a car, and ask why the car in the first picture does 0-100 in three seconds and the one in the bottom does it in 5 seconds.

This is not the same system. The first is a drive EVO 970. Sometimes runs on a system that has a 5th generation i10 processor (sometimes runs on another system, but I will currently only refer to a 10th generation), built-in video card. Do you have more data?

 

The second drive - came with the laptop. No model listed, no speed listed and nothing. I hope I am not confused by the sub-model:

Intel® Core ™ i5-10300H Quad Processor, 8M Cache, 2.50 GHz up to 4.50 GHz

16GB 2933MHz (2 x 8GB) Up To 16GB

512GB M.2 2280 PCIe NVMe

NVIDIA GTX 1650Ti, 4GB GDDR6

 

I am curious why the backups are significantly slower on the other computer. I will note that the backups are done to the drive External with a write and read speed of about 1 GB per second. I initially thought it was called a drive Relatively slow on the mobile, but the speed shows that the drive is not bad at all.

 

I tested with the same software.

Your description is still not entirely clear.

The above software does a brief test.

TLC-based drives initially work on one or another cache that is fast but if you read / write the whole drive continuously the speed drops very significantly. This is very significant in writing but I think it also affects reading. 

The 970 is a very good drive where the above drop is moderate (but despite everything exists to the best of my recollection) the OEM drive you get on your computer It is certainly less quality. You can see the model in the device manager.

 

Accordingly a continuous reading of a large amount of material will not match the performance of the short test.

What other data do you need?

I checked:

UMIS RPITJ512VME2OWD

I do not know

As far as I understand the software should also perform testing for larger files. I guess this's the third or fourth line, but I'm not sure.
