Ho fatto un po' di prove trasferendo un file di 2.40gb dai due dischi incriminati al SSD primario in cui č installato il sistema operativo e li ho cronometrati

Seagate 320GB interno SATA interno --> Crucial M4 SATA interno: 1m:04s
Maxtor One Touch 750GB USB --> Crucial M4 SATA interno: 59s

Mi sarei aspettato un tempo molto minore per il primo, invece risulta addirittura pių lento

Quindi ho provato a fare un test veloce con CrystalDiskMark confermando i miei dubbi....

a titolo di esempio ho messo anche il risultato dell'SSD e di un disco malfunzionante attaccato alla usb del router

E possibile che il disco fisso interno sata stia funzionando in modalita pio mode , prova a controllare in gestione periferiche di windows .
Per sicurezza prova a fare anche un test per cercare eventuali settori danneggiati che potrebbero rallentare il disco fisso .

non ho quell'opzione...

comunque facendo i test con 4000MB invece di 50 ho risultati migliori
