Product Description:

The 5AC901.CSSD-03 solid-state drive module is produced by B & R Automation within the 5AC CNC Addon Modules series. It serves as removable mass storage for numerical-control platforms, maintaining program code and machine parameters after power cycling. Positioned on a carrier board beside the motion CPU, it preserves tool offsets, axis calibration data, and logged events that support deterministic operation. Its mechanical outline mirrors other 5AC modules in the rack, so it fits the same slot arrangement while retaining consistent height, depth, and cooling clearances.

The drive has a capacity of 60 GB and uses multi-level cell flash identified as MLC. A board-edge connector carries the standard SATA interface to the controller, enabling sustained sequential transfers that peak at Max. 520 MB/s during reads and reach Max. 180 MB/s during writes. Random performance on 4 kB blocks benefits boot sequences and real-time logging in closed-loop machining. The enclosure stands 98 mm high, extends 105 mm deep, and measures 13 mm wide, dimensions that allow it to fit beside servo electronics without blocking cabinet airflow.

For extended duty cycles, the drive supports a client workload of 75 TBW, indicating the cumulative bytes that can be written before wear-leveling reserves are depleted. Data reliability is specified as an uncorrectable error rate no worse than 1 per 10^15 bits read, matching long production runs where fault tolerance is required. The controller processes up to 75,000 random read IOPS on 4 kB accesses, helping the CNC interpreter fetch small parameter files quickly. Even with this throughput, the assembly weighs only 118 g, so enclosure vibration loads remain low during high-speed spindle acceleration.
