@frankm Alles Klar!
Wie schon erwähnt, für meine Zwecke rechts! Die Jahre über hat gute Dienste geleistet (PCI-e und HDD) und wird hoffentlich auch noch ein paar Jahre bis zum nächsten Umbau tun!
Vielen Dank!

Hier möchte ich alle Benchmarks usw. sammeln. Bitte unbedingt das vorher lesen! Ich werde die Version des Images dabei schreiben. Einsetzen werde ich ausschließlich folgendes Image.

Macht bis jetzt für mich den stabilsten Eindruck.

USB2/3 (Version 0.7.3)
Ich benutze eine SAN Disk 240GB SSD an einem Inateck USB 3.0 2,5 Zoll Adapter.
Info zum USB-Adapter
lsusb Bus 004 Device 002: ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge2,5 Zoll SSD am USB2-Port

sudo dd if=/dev/zero of=sd.img bs=1M count=4096 conv=fdatasync 4096+0 records in 4096+0 records out 4294967296 bytes (4.3 GB, 4.0 GiB) copied, 36.2588 s, **118 MB/s**Der @tkaiser erreicht deutlich höhere Geschwindigkeiten. Bis zu 400 MB/s. Hier nachzulesen.
Ich habe mich mit @tkaiser noch mal unterhalten. Scheint sehr deutlich ein Problem des Adapters zu sein. Da müsste eigentlich mehr gehen. Mal sehen....

Gestern mal was praxistaugliches aufgebaut. Auf dem ROCKPro64 einen NFS-Server installiert. Die Freigabe lag auf der NVMe SSD. Das ganze dann auf meinem Haupt-PC gemountet und mal einen Star Wars Film kopiert. 8,5 GB
