La velocit\u00e0 massima \u00e8 rimasta invariata e si attesta a 6 Gbit\/s.

In primo luogo, c'\u00e8 la funzione tecnica Device Transmit Emphasis for Gen 3 PHY. Questa permette di concentrarsi sul dispositivo di trasmissione, allineando SATA con altre soluzioni di input\/output nella misurazione delle loro caratteristiche. Questa funzione dovrebbe aiutare nella fase di test e integrazione delle interfacce dei nuovi dispositivi.<\/p>\n<p>In secondo luogo, nelle specifiche SATA \u00e8 stata introdotta la funzione di ordinamento dei comandi NCQ o Defined Ordered NCQ Commands. Essa consente all'host di specificare le relazioni tra i comandi in coda e stabilisce l'ordine in cui questi comandi vengono elaborati.<\/p>\n<p>La terza nuova estensione della SATA Revision 3.5 \u00e8 stata la funzione Command Duration Limit Features, che limita la durata dei comandi. Questa funzione \u00e8 progettata per ridurre i ritardi, consentendo all'host di definire categorie di qualit\u00e0 del servizio grazie a un controllo pi\u00f9 dettagliato delle propriet\u00e0 dei comandi. Inoltre, questa funzione aiuta a conformarsi ai requisiti di \"Fast Fail\" stabiliti dall'Open Compute Project (OCP) e indicati nello standard del Comitato Tecnico INCITS T13. Di conseguenza, la nuova revisione della SATA ha incorporato tutti gli aggiornamenti pi\u00f9 recenti dello standard T13.<\/p>\n<p><center><\/center><\/p>\n<p>Infine, le specifiche SATA Revision 3.5 hanno incluso correzioni e chiarimenti delle specifiche SATA 3.4.<\/p>\n<p>Si prevede che l'ottimizzazione del processamento dei comandi e la correzione degli errori nella nuova versione SATA Revision 3.5 contribuiranno a ridurre i casi di \"colli di bottiglia\" durante il trasferimento intensivo di dati tramite l'interfaccia SATA, il che \u00e8 solo da accogliere favorevolmente.<\/p>\n<p><strong>Fonte:<\/strong><\/p>\n<ul class=\"related\">\n<li><noindex><a rel=\"nofollow noopener noreferrer\" href=\"http:\/\/www.cdrlabs.com\/\" target=\"_blank\"
