no servidor temos 2 hdd de 2 TB ligados a portas sata e 1 ssd samsung 970 evo nvme M.2 (2280) de 250 GB ligado ao barramento pcie.

a ideia é utilizar os dois hdds num raid nível 1 por software com o mdadm, com os discos encriptados e deteção de erros ao nível do bloco (integridade assegurada por dm-integrity) e o ssd como cache destes.
