Hi,

Благодаря стечению обстоятельств удалось наконец замерить
производительность контроллера 3ware 9550SX в стендовых условиях.

Результат измерения оказался настолько неожиданным, что я подозреваю
наличие какой-то ошибки в настройке или эксплуатации контроллера.
Дело в том, что усреднённая производительность 9550SX при работе с одним
диском оказалась на 25% ниже, чем у обычного набортного nVidia MCP51.

# ./tw_cli /c0 show all
/c0 Driver Version = 2.26.02.008
/c0 Model = 9550SX-4LP
/c0 Memory Installed  = 112MB
/c0 Firmware Version = FE9X 3.08.00.004
/c0 Bios Version = BE9X 3.08.00.002
/c0 Monitor Version = BL9X 3.01.00.006
/c0 Serial Number = [...]
/c0 PCB Version = Rev 032
/c0 PCHIP Version = 1.60
/c0 ACHIP Version = 1.70
/c0 Number of Ports = 4
/c0 Number of Units = 4
/c0 Number of Drives = 4
/c0 Total Optimal Units = 4
/c0 Not Optimal Units = 0 
/c0 JBOD Export Policy = off
/c0 Disk Spinup Policy = 1
/c0 Spinup Stagger Time Policy (sec) = 3
/c0 Auto-Carving Policy = off
/c0 Auto-Carving Size = 2048 GB
/c0 Auto-Rebuild Policy = on
/c0 Controller Bus Type = PCI
/c0 Controller Bus Width = 64 bits
/c0 Controller Bus Speed = 66 Mhz
[...]

Хотелось бы понять, откуда взялись тормоза на 9550SX и как их избежать?
