SATA SSDs

SATA SSD Performance & Benchmark Tests

Here you can find 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* (theoretically). In practice, up to approx. 550 MB/s are possible for reading and writing. SATA SSDs are slower compared to PCIe NVMe SSDs and therefore also 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.

When does a SATA SSD make sense?

There are actually 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.
To 1) Often, older laptops 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.
To 2) The use of an M.2 SSD is absolutely recommended for desktop PCs. If your mainboard does not have an M.2 slot, you can also use a PCI Express adapter to use an M.2 SSD. The operating system and programs should definitely be installed on the fast M.2 SSD. Here, 256 or 512 GB are often sufficient. If you need more storage space (for MP3s, photos or videos), you can buy a cheap SATA SSD. SATA disks are a bit cheaper than M.2 disks with about 0.10 Euros per gigabyte.

SATA and X570 = Bad Performance

After I had tested several SATA disks, and none of them achieved write rates over 460 MB/s (although the manufacturers had specified 530 MB/s), I became a bit suspicious whether this could be due to my test system. I connected the disks to different SATA ports of my mainboard and performed several tests with different programs (AS SSD, ATTO, CDM). Always with the same result, that I did not get good values (especially in the 4K test).

I then researched on the Internet and came across an article of a Reddit user, which also showed this problem and could trace the problem back to the AMD X570 chipset. The same SATA disk delivers much better transfer rates on a B550 motherboard.

However, since my test system (see home page below) uses an X570 motherboard (only this currently supports M.2 SSDs of Gen. 4), it does not make sense to test more SATA SSDs here, since not the SSD but the AMD chipset is the bottleneck here. I hope that a future BIOS firmware update will fix this problem. Until then, I will post the tests here (status: December 2020).
