Featuring 1GB of DDR3 cache memory, this module buffers incoming write requests to significantly reduce write latency and optimize IOPS performance across RAID storage arrays. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eUnlike traditional Battery Backed Write Cache (BBWC) units that rely on temporary battery power to retain cached data during power loss, FBWC technology uses supercapacitors to quickly transfer dirty cache data from volatile DRAM to non-volatile flash memory in the event of a power outage. This flash-based architecture eliminates the need for battery replacements and ensures permanent data retention without time degradation during prolonged power loss. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAvailable from DataDive, your \u003ca href=\"https:\/\/www.datadive.qa\/\"\u003etrusted Server Parts Supplier in
