[RE: CONFIG.SYS of Shohei Yamada] How to use the high -speed port of USB4 -PC Watch
Cloud storage that is too late to get along
Clouds are now being used for use, such as sharing data with someone or copying files for backup, but the ease of use still has nothing to do with USB memory.In the general public, USB is enough to point to USB memory, not the standard name.
This time, in order to make the copy work a little quicker, I procured a high -speed SSD and tried various cases.For each device used for the test, we asked Western Digital GK and ITG Marketing Co., Ltd., a Samsung specialty agent.For PCs, I used Lenovo's ThinkPad X1 nano.This PC is equipped with two Type-C ports on the left side of the main unit, and both ports are compatible with Thunderbolt 4.It is also clean that there is no Type-A port.From now on, this will be a matter of course.
As for the work, I copied the file from the external SSD to the built -in SSD, assuming a large amount of files from someone.We have prepared a folder in a mixed -up state where various files are mixed, with 1,732 files and 175 folders.The total capacity is 28.There is 3GB.
First, I tested it using the 2TB version of "Sandisk Extreme Pro Portable SSD V2".This SSD is USB 3.It is a reliable product that has a characteristic of 2 meters of falling from 2m and waterproofing of IP55 with 2 Gen2 × 2 compatible.For strange reasons, I try using Thunderbolt 4 cables to connect so that the cable does not become a bottleneck.
The result is about 2 minutes and 30 seconds, the copy is completed.The ability is about 200MB/s.As for the product specifications, the sequential reading and writing are 2,000MB/s, and even if you test with CristalDiskMark, the sequential result is more than 1,000MB/s, but the test in the benchmark and the practical range is different.
Interestingly, the same performance was given to the connection with the Gen1 cable.In this SSD, you can copy at a reasonable speed with any cable.Also, if a folder with the same content is copied in the SSD, it is very fast, about 2 minutes and 10 seconds.In addition to reading, he is doing well about writing.It's a magical device.It's just an imagination, but the Gen1 cable may have hit this result in the best effort.
Thunderbolt 4ケーブルでサンディスク エクストリーム プロ ポータブルSSD V2を接続したときの計測結果。Gen1ケーブル、Gen2ケーブル、どちらでも同程度の結果が得られた。I uploaded the same content for ONEDRIVE in the cloud storage, but it took almost 40 minutes on the optical internet that I used regularly.
The external SSD connected to the notebook PC USB port can transfer more than 200MB/s data transfer to 1TB capacity file copy 1..It takes about 5 hours.Is the unit waiting time of more than an hour in PC work really long or short?
