Instructions

En TRIM-kommando, kjent som TRIM i ATA-kommandosettet og UNMAP i SCSI-kommandosettet, lar et operativsystem informere en SSD-stasjon om hvilke blokker som ikke lenger anses å være i bruk, og som kan slettes internt. Trimming gjør det mulig for SSD å håndtere søppelinnsamling mer effektivt, noe som ellers ville redusere fremtidige skriveoperasjoner til de involverte blokkene.

TRIM for SSD-er er oppført som en funksjon i PERC-familien. Det er rapportert at TRIM bare er støttet i HBA-modus og ikke i RAID-modus.

 

Siden januar 2017 er ikke støtte for TRIM-kommandoen implementert i de fleste maskinvarebaserte RAID-teknologier. Programvare-RAID-implementeringer kan imidlertid ofte inkludere støtte for TRIM. TRIM-funksjonen støttes bare på pass-through-SSD. Se i S130-brukerveiledningen for å finne ut hvordan du utfører TRIM på pass-through-SSD.
