At 18TB with 7200 RPM spindle speed, it delivers the throughput and capacity needed for high-intensity workloads — file archiving, large-scale sharing, RAID array rebuilding, and continuous 24\/7 operation. NASware 3.0 firmware optimizes every aspect of NAS integration: compatibility, RAID error recovery, vibration tolerance, and performance tuning for multi-bay enclosures.\u003c\/p\u003e\u003cp\u003eCMR recording technology ensures stable, predictable write performance in RAID configurations and extended file systems such as ZFS — unlike SMR drives which can stall during RAID rebuilds. The multi-axis shock sensor and Dynamic Fly Height technology work together to protect data integrity in large 24-bay chassis where mechanical vibration from adjacent drives is a constant factor. Every drive ships with extended thermal cycle burn-in testing for verified reliability before deployment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium to Large Business NAS\u003c\/strong\u003e — Up to 24-bay NAS systems for enterprise-scale file storage and sharing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRAID \u0026amp; ZFS Arrays\u003c\/strong\u003e — CMR for reliable RAID 0\/1\/5\/6\/10 and ZFS array performance and rebuild times\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Capacity Archive Storage\u003c\/strong\u003e — 18TB per drive for cost-effective large-scale data archiving and retention\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24\/7 Business-Critical NAS\u003c\/strong\u003e — 550TB\/year workload rating and 5-year warranty for always-on environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Bay Vibration Environments\u003c\/strong\u003e — Shock sensor and 3D Active Balance Plus for 8–24 bay enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e — WD Red Pro\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN\u003c\/strong\u003e — WD181KFGX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU\u003c\/strong\u003e — CCWD181KFGX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e — 18TB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e — 3.5\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterface\u003c\/strong\u003e — SATA III 6Gb\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Speed\u003c\/strong\u003e — 7200 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCache\u003c\/strong\u003e — 512MB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecording Technology\u003c\/strong\u003e — CMR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax NAS Bays\u003c\/strong\u003e — Up to 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorkload Rating\u003c\/strong\u003e — 550TB\/year\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24\/7 Rated\u003c\/strong\u003e — Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e — 5-year limited\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Western Digital","offers":[{"title":"Default Title","offer_id":50945091699009,"sku":"CCWD181KFGX","price":736.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/5524\/8705\/files\/WD161KFGX_2.webp?v=1763061257","url":"https:\/\/aaawave.com\/products\/wd-red-pro-18tb-nas-hdd-wd181kfgx","provider":"AAAWave","version":"1.0","type":"link"}
