Warner Losh 50ee2e2aab Send IDLE IMMEDIATE for warm boot. ... We must send either an IDLE IMMEDIATE or a STANDBY IMMEDIATE to drives on warm boot so their SMART and other volatile data is persisted. However, for a warm boot we don't want to send STANDBY IMMEDIATE to some spinning drives because they will spin down. If there's a lot of these drives on the system, that can cause a thundering herd problem at startup time (that in extreme cases causes timeout in device discovery).
