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.

The FireCuda 520 is solid and promises a long service life according to the manufacturer. Cooling fins are not available free of charge.

The FireCuda 520 from Seagate is a very good SSM with excellent performance. However, it lacks a heat sink and there are significantly cheaper SSMs that deliver similar performance.
