Hallo,
mal ne allgemeine Frage.
ich habe windows Vista 64bit im Einsatz auf einem Perc 5 mit 8x 750 gb hdd (samsung F1) im raid 5
Das Tool hdtune misst immer mur 7mb/s also irgendwie kommt es mit dem OS oder der Kapazität nicht klar.
Bei 5x750 Gb im Raid 5 hatte ich ca 240mb/s laut hdtune.
Naja ich habe nun iozone getestet.
Hier sehen die Werte eher ernüchternd aus. Kann einer von euch vergleichstests machen?
hier die Settings:

C:\Program Files (x86)\benchmarks\Iozone 3.321>iozone -R -l 5 -u 5 -r 128k -s 7G
-F d:\iozone\1 d:\iozone\2 d:\iozone\3 d:\iozone\4 d:\iozone\5
Results:
C:\Program Files (x86)\benchmarks\Iozone 3.321>iozone -R -l 5 -u 5 -r 128k -s 7G
-F d:\iozone\1 d:\iozone\2 d:\iozone\3 d:\iozone\4 d:\iozone\5
