Curious: among the fast PCI Express 4.0 SSDs, two models achieved both test and price-performance victory thanks to identical test scores and the same sales price - the Western Digital Black SN850 and the Samsung 980 Pro. This is rare for Computer Bild.

It's fascinating how fast SSDs have become - even faster with PCIe 4.0. However, this comparative test also seems to reveal an unattractive tendency: The faster the SSDs become, the less durable they are likely to be. At least that is what the TBW suggests. However, we did not measure this.

What a debut: The Western Digital WD Black SN850 was faster in the test than any other SSD in the Computer Bild lab. It is therefore the new number one SSD, albeit a rather expensive one: it costs twice as much as a comparable PCI Express 3.0 SSD.

The WD_Black SN850 is the clear test winner. It is faster than all the others, but you still have to buy a heat sink.
