FAcile notare come sia presente nella lista dei dischi testati anche l'atteso Fujitsu MAM3XXX, dotato di regime di rotazione di 15.000 giri.
I risultati migliori sono stati ottenuti, nel campo dei dischi a 15.000 giri, dal modello Cheetah X15, seguito dall'ottimo Fujitsu a 15.000 giri della serie MAM3XXX. <BR>
Per quanto riguarda i modelli dotati di regime di rotazione di 10.000 giri i test hanno messo in evidenza le ottime prestazioni del disco Fujitsu serie MAN3XXX, recensito anche in una delle nostre prove, precisamente a </i></blockquote> <a href=http://www.hwupgrade.it/articoli/293/index.html>questa pagina.</a><BR><BR>
Riportiamo le conclusioni ottenute nella seguente citacione, in lingua inglese:

<blockquote><i>Although Seagate is leading an aggressive policy other companies do not give up. The long-awaited Maxtor Atlas 10K III performed quite well, especially in the integrated ZDLabs tests. This disc was announced in Q1 2001; it belongs to the third generation of 10K RPM discs from Quantum. It should be noted that reorganization of Quantum and Maxtor caused delays in delivery of this model, but it still successfully competes against the latest products from Seagate. <BR><BR>

Fujitsu keeps on producing high-quality products. The MAN3xxx series is the fifth generation of 10K RPM drives of this company. Its first drive in the 15K RPM class is quite competitive as compared with the G2 of 15K drives from Seagate, a leader in this field. Both drives from Fujitsu take the leading positions in this class in the IOMeter tests. <BR><BR>

Seagate is a confident leader in technologies. Among its products there is the fastest disc of 15K RPM - Cheetah X15 36LP. It is the second generation of X15 discs which beats the first one by 12% in the access time and by 50%(!) in linear reading speed. In the 10K RPM class the performance is gradually increasing as well: the Cheetah 36ES and Cheetah 73LP models of the G5 and G6 in the Cheetah series outscore the first 15K RPM models from Seagate in the Winbench test. <BR><BR>

And now we are waiting for IBM to launch its 10K RPM Ultrastar 73LZX model and the second competitor against the Cheetah X15 - Ultrastar 36Z15.
