MRA503R 1 x 2.5＂ & 2 x 3.5＂ Raid Mobile Rack
|
MRA503R takes two 5.25” space and supports 2bay Raid for 3.5” HDD plus 2.5” Rack for spare SSD. All metal parts and intelligent temperature control design which provide more rigid quality and greater heat dissipation. It provides reliable data protection and allows HDD hot-swap life cycle for more than 50,000 duty cycles using the patent NSS connector. |

 |
Ultra-rugged and High quality frame Aluminum outer case, hairline finish, durable and greater heat dissipation. Zinc Alloy door handle can bear over 20KG pull without broken and deformation. SUS430 ejection mechanism, SGCC back cover, Zinc Alloy hook, High-strength heat-resistant fire-rated PC, and aluminum track.  Strong zinc alloy door handle Metal parts percentage |
|
Provides fast and secure RAID function (JBOD, NOR, RAID1, RAID0) |
 |
|
It supports 2.5” Rack for spare SSD + 2bay Raid for 3.5” HDD
|
 |
|
Compatible with thicker and thinner HDD When the product needs to be used in upright position, thinner HDD might be move around since HDD is in upright position as well. 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 60mm 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) Alarm system: buzzer for the fan failure or internal temperature exceeds the setting maximum temperature. |
|
Independent power switch The first button can power on and off 2.5" Rack The second and third button can power on and off two bays x 3.5" synchronously to prevent Raid error caused by mistakenly button press during RAID |
 |
|
Memorize function
MRA503R 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 MRA503R manually, it can automatically restart and back to previous working status to achieve unattended intelligent mode.
