Ha senso aggiornare il driver Intel Rapid Storage in Win7?

[retalv]

Premessa alla domanda: penso che l'unica cosa che mi riguardi sia la funzione TRIM per SSD già compresa in Win7x64... non uso RAID di alcun tipo, il bios (Asus Deluxe) supporta SATA3.

Ha un senso l'aggiornamento con l'ultima versione 10.8, a parte il piccolo incremento in lettura sequenziale e casuale?

Quelle che seguono sono le differenze di uso a seconda dei drivers installati.
