For heaviest server dutyThese three HDD backplanes are well-proven in extremely hard server duty.Even with highest transfer rates they run very smoothly. That’s why werecommend them for the demanding duty in RAID systems.Accordingly elaborate is the temperature control. The aluminium parts dissipatethe heat. The 80-mm fan operates reliably and silently. If necessary it is easilyremoved or attached, no tools needed. For the case of a too high temperaturethere are optical and acoustic signals.All moving parts are layed out for strongest strain. The trays and their lockingmechanism are extremely fitting. They slide without resistance. The aluminiumparts are electropolished.
