Those onboard controllers are usually connect to 8x PCIe or similar. Also, those controllers from LSI won't allow TRIM support, which may come in handy…

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
