Am I the only one who thinks RAID controllers are a placebo and wouldn&#x27;t trust anything but ZFS?<p><i>What was even more interesting is that our SSDs are connected to the Dell H700&#x2F;H710 RAID controller which has a battery backup unit (BBU) which should make our drives power failure resilient. RAID controller with BBU in case of a power failure can hold the cached data until the power comes back, so that it can flush it to the drives when the drives come back online.</i>
