La prova, veramente ben condotta, pende in considerazione tutti gli aspetti prestazionali, che vanno dalla misurazione del tempo di accesso e alle prestazioni a basso livello in genere, fino ai test Winbenc e Io meter. <BR>

E' dunque facile consultare questo articolo avendo a disposizione i dati comparativi dei risultati ottenuti. Molto interessante l'analisi prestazionale condotta utilizzando interfacce diverse, ovvero ATA 33,66 e 100. <BR><BR>
Anche i risultati del test Iometer permettono di trarre interessanti considerazioni.<br><br><center><img src="http://news.hwupgrade.it/immagini/iometer.gif"></center><br><br>
Facile notare come, fra tutti i dischi testati, il modello IBM, pur essendo superato nelle misurazioni di transfer rate e non solo, sia il disco più performante in sitazioni di ambiente simulato attraverso questo speciale test, il più veritiero. Le prestazioni comunque sono buone per tutti i dispositivi, grazie alle innovazioni tecniche introdotte nel corso degli ultimi due anni.

Bhè, meno male che il mio povero Quantum si difende ancora

Anche il mio Ibm 60GXP che monto tra qualche giorno al posto del mio DTLA
