Netcup SSD speed difference

Hi all!

I read a lot before I bought netcup root server and I realised an interesting difference.

I saw that on older RSs the reachable SSD speeds higher than currently. I saw a lots of YABS and I see that currently maximum is near at

Write 1.69 GB/s (3.3k) 1.65 GB/s (1.6k)
Total 3.30 GB/s (6.4k) 3.20 GB/s (3.1k)

On older benchs, I can see double speeds (near 300 MB/s on 4k, more than 3 GB/s on 64k and near 5--7 GB/s on 512k and 1m).

RS packages are very useful with currently specs and available SSD speeds. But I'm interested in that is it a limitation to keep the quality for all customers?

    Well, my current RS is getting slower speed than yours.

    Some may be on luckier (less crowded) nodes than others. but TBH I think this kind of speed is still enough for most use cases.

    Speed differs, so what
