Споделям мнението на цеци, подобни RAID контролери много рядко са добър избор, Причините да са лош избор са следните: 1. Трудно се подкарват да работят правилно 2. При счупване на масива ти си ограничен до софтуера който имаш в BIOS-а и съответно има много ситуации в които все едно нямаш RAID 3. В повечето случаи софтуерният RAID на Linux ядрото вади по добър performance отколкото този на дъното.
