Product Description:

The 5A5001.16 rotating hard disk is produced by B & R Automation as part of the 5A5 Hard Disks series. Installed inside industrial PCs, PLCs, or controller racks, it supplies magnetic mass storage for operating systems, motion tables, and production logs that must persist through power cycles. This type of storage is useful when the control platform must retain system images, user recipes, and long-term event histories after shutdowns or controlled restarts. The drive connects through the standard ATA-6 bus used in many embedded automation platforms, allowing the host system to access the disk without extra interface cards and helping preserve a compact footprint inside the control cabinet.

The platter stack provides a formatted capacity of 30 GB, buffered by a 2 MB cache that reduces command latency for repetitive sector reads and writes. Host controllers exchange data over the ATA-6 port at up to 100 MB/s, while the internal medium can sustain sequential transfers of 36.2 MB/s. With platters spinning at 4,200 rpm, the disk needs only 5 seconds from power-up to reach nominal speed. Encoding density reaches 592 kbpi across tracks written 24,200 times per inch, and each 512-byte sector is addressed within a logical map totaling 58,605,120 user sectors. The cache and sector layout support predictable access behavior during recurring read and write activity in real-time logging applications.

Head dynamics contribute an average access latency of 7.14 ms, while complete seek operations across cylinders finish in about 12 ms, which helps limit delay during routine file retrieval and buffer loading. Mechanical precision is supported by a track density of 24,200 TPI, keeping the read/write gap aligned with narrow data bands during vibration that is common on factory floors. The drive’s expected service window is 20,000 POH, which supports scheduled maintenance intervals in continuously operating automation equipment over long production runs.
