That depends entirely on what you're trying to achieve.

RAID0, then.

IMG_20190909_010730.thumb.jpg.aa5990b9a94407d5d5a7acfc534f95df.jpgBut I will get very low speeds on 4KiB  Q1T1. Is that natural or is it something wrong with my ssd?

Yes, it's normal.

That test simulates opening a file, writing 4 KB of data into it, closing the file, and repeat the process hundreds of times a second. Hence you get 18 MB/s ... 18000 KB / 4 KB = 4500 operations per second.

 

A SSD is optimized for larger chunks of data and most of the time, your applications don't work like that, reading and writing only 4 KB of data at a time.
