Here are detailed speed performance tests of SATA 6 Gb/s SSDs. The maximum speed here, limited by the SATA III interface, is only 600 MB/s* (theoretical). In practice, a speed of up to approx. 550 MB/s is possible for reading and writing. SATA SSDs are slower compared to PCIe NVMe SSDs, which makes them cheaper. Therefore, they are usually used as a backup or data grave when the speed is not that important.

*) The SATA Express (SATAe) successor with 8 and 16 Gbit/s has also been available since 2013, but it did not succeed because of the faster M.2 interface.
There are really only two applications where a SATA drive still makes sense: 1. in older laptops that do not have an M.2 slot and 2. as a fast storage expansion in a desktop PC.
Regarding 1): Older laptops often still have a mechanical 2.5" HDD installed, which is connected to the SATA port. You can achieve a significant and noticeable speed increase by removing the mechanical HDD and installing a SATA SSD instead.
Regarding 2): The use of an M.2 SSD is highly recommended for desktop PCs. If your motherboard does not have an M.2 slot, you can use a PCI Express adapter to use an M.2 SSD. The operating system and programs should be installed on the fast M.2 SSD. 256 or 512 GB is often enough. If you need more storage space (for MP3s, photos or videos), you can buy an inexpensive SATA SSD. SATA disks are a bit cheaper than M.2 disks at about 0.10 Euro per gigabyte.
After testing several SATA hard drives, none of which achieved write rates above 460 MB/s (although the manufacturers claim 530 MB/s), I became suspicious that my test system might be to blame. I connected the drives to different SATA ports on my motherboard and ran several tests with different programs (AS SSD, ATTO, CDM). The resulting values were bad every time (especially in the 4K test).
I then did some research online and came across an article by a Reddit user that also showed this problem and was able to trace it back to the AMD X570 chipset. The same SATA drive performs much better on a B550 motherboard.
However, since my test system (see home page below) uses an X570 motherboard (only this currently supports Gen. 4 M.2 SSDs), it makes no sense to test more SATA SSDs here, since it is not the SSD that is the bottleneck, but the AMD chipset . I hope that a future BIOS firmware update will fix this problem. Until then, I will post the tests here (status: December 2020).
