These three hard drive backplanes have proven themselves in demanding server environments. They can operate with both SATA and SAS drives. They remain extremely stable even under very high data throughput, making them particularly recommended for demanding applications in RAID systems. The temperature control is correspondingly sophisticated. The aluminum components dissipate heat, and the 80mm fan operates reliably and quietly. Should the interior of the case become too hot, acoustic and visual signals will provide warnings. All mechanical parts are designed for high loads. The drawers and their locking mechanisms are extremely precise and glide effortlessly. The aluminum parts are electrolytically sealed. The IB-56x series is well-equipped for extreme loads. To meet modern security requirements, the case can also be locked. The high-quality metal dissipates the generated heat to the environment through passive convection. Active convection is supported by an 80mm fan. The larger fan operates more efficiently even at lower speeds, keeping the case quiet.
