A “portable SSD” that is neither a USB memory nor an HDD will completely change the way you use your laptop! Large capacity + high speed + safety is the decisive factor

Comparable speed compared to internal storage

Then, actually, WD My Passport SSD (2020 version) 1TB model, HDD type WD My Passport (2TB model) , USB memory (256GB) with USB 3.1 Gen1 connection is connected to the laptop, and the graph below compares the transfer speed with CrystalDiskMark. The latest WD My Passport SSD has excellent performance, and the actual measurement value of the benchmark test has achieved sequential read performance that reaches 1 GB / s.

Neither USB memory nor HDD

We also measured the speed when reading and writing a 5GB file to each device (copying from the internal SSD of the laptop to each storage, and copying from each storage to the internal SSD of the laptop, 3 times trial average). As a result, the read speed is 7 times faster than HDD and USB memory, and the write speed is nearly 4 times faster than HDD.

File copy measurement result. The extremely slow reading from the USB memory (copying from the USB memory to the internal SSD) seems to be due to the fact that the cache has run out. . For example, even when you place the installation file of a PC game and start the game or move between scenes, the level is the same as when you save it in the internal storage.

Therefore, we measured the startup time of Square Enix's "Final Fantasy XIV: Jet Black Villains Benchmark". The computer is the same laptop that was used for the read/write performance test, with the graphics settings preset set to Best Quality and the display screen setting set to Full Screen.

In the test, we saved the executable file on WD My Passport SSD and portable HDD, and measured the boot speed from there. As a result, it took 18 seconds for the built-in SSD and WD My Passport SSD with PCI Express connection, while it took 27 seconds for the HDD type WD My Passport. If only this is different, you can feel it clearly.

Also, when I put a large material file on the WD My Passport SSD and tried editing a video file, etc., reading the material file and running the application The feeling of operation and responsiveness during editing was at a level where I could hardly feel the difference from when I put the material in the internal storage. It can be said that it is a gift of good response by USB 3.2 Gen2 and NVMe SSD. This is a convenience that cannot be achieved with HDD type or USB memory.
