High capacity Supports 5 x 3.5" SATA HDD in 3 x 5.25" space. Maximum capacity up to 30TB (6TB*5) |
 |
|
Compatible with thicker and thinner HDD
To fully utilize 5 x 3.5" SATA HDD in 3 x 5.25" space, HDD will be used in upright position.
Patent alignment mechanism make sure thinner HDD connected to backplane firmly. (Patent applied in many countries)  |

Excellent heat dissipation
Set proper Airflow by vent of front bezel and space between HDDs, plus 80mm fan to enhance heat dissipation, control the HDD surface temperature does not exceed the environmental temperature of 15 degrees, let the HDD works in the normal temperature range any time.
Intelligent temperature control system When the internal temperature reaches 30 °C, the fan starts running, which extend fan life cycle. Fan speed will be adjusted automatically by the temperature change, fan spins at the highest speed when the temperature reaches 40 °C. (HIGH Mode : Fan spins at the highest speed when the temperature reaches 30 °C) Dual alarm system: buzzer and LED for the fan failure or internal temperature exceeds the setting maximum temperature. |
|
Individual power switch
Every single HDD corresponds to a power switch button, press the power switch button for 3 seconds to power on or off.
Power on / off for all bays quickly One button can power on /off all bays sequentially. Time saving and avoid current increased dramatically. |

|
Memorize function MRA505 will memorize previous working status of every HDD if it occurs sudden power failure during use. It will automatically restart and back to previous working status after restoring power. This feature is designed primarily for surveillance, servers and other equipment that required long time uninterrupe work. When the power failure occurs during use, after power restore, there's no need to restart MRA505 mamualy, it can automatically restart and back to previous working status to achieve unattended intelligent mode.。 |
