Voici les résultats (pour info, c'est un disque SAT 5400 trs/min) :

Disque IDE :

6.Workbench:> c:scsispeed DRIVE a1ide.device:0 FAST BUF1=8192 BUF2=16384 BUF3=32768 BUF4=65536
MKSoft ScsiSpeed 4.2 Copyright ? 1989-92 MKSoft Development
AmigaOS4 port by Stéphane Guillard
------------------------------------------------------------
CPU: 68020 AmigaOS Version: 53.8

Testing with a 8192 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 25534873 bytes/sec

Testing with a 16384 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 28804710 bytes/sec

Testing with a 32768 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 30962483 bytes/sec

Testing with a 65536 byte, MEMF_FAST, LONG-aligned buffer.

Disque SATA :

6.Workbench:> c:scsispeed DRIVE sii3114ide.device:3 FAST BUF1=8192 BUF2=16384 BUF3=32768 BUF4=65536

AmigaOS4 port by Stéphane Guillard
------------------------------------------------------------
CPU: 68020 AmigaOS Version: 53.8
Device: sii3114ide.device:3


Testing with a 8192 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 24494489 bytes/sec

Testing with a 16384 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 31824281 bytes/sec

Testing with a 32768 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 37850316 bytes/sec

Testing with a 65536 byte, MEMF_FAST, LONG-aligned buffer.
Read from SCSI: 41022259 bytes/sec

La grosse différence néanmoins est dans l'utilisation CPU, bien moindre en SATA qu'en IDE.
