Instructions
Un comando TRIM, conocido como TRIM en el conjunto de comandos de ATA y UNMAP en el conjunto de comandos de SCSI, permite que un sistema operativo informe a una unidad de estado sólido (SSD) qué bloques de datos ya no se consideran en uso y se pueden borrar internamente. El recorte permite que la SSD maneje de manera más eficiente la recolección de elementos no utilizados, lo que, de otro modo, ralentizaría las futuras operaciones de escritura en los bloques involucrados.
TRIM para SSD se enumera como una característica de la familia PERC. Se ha informado que TRIM solo se soporta en el modo HBA y no en el modo RAID.
A partir de enero de 2017, la compatibilidad con el comando TRIM no está implementada en la mayoría de las tecnologías RAID basadas en hardware. Sin embargo, las implementaciones de RAID de software a menudo incluyen soporte para TRIM. Además, la función TRIM solo es compatible con las SSD de paso. Para saber cómo realizar TRIM en SSD de paso, consulte la Guía del usuario de S130.
