Seagate近日透露,計畫在18月內推出一塊14TB或者16 TB容量的3.5寸機械硬碟產品
採用HAMR熱磁輔助記錄技術,其將包含8塊碟片與16個磁頭
目前12TB容量的3.5英寸機械硬碟產品正在測試中
據CEO Stephen Luczo表示早期的回饋非常正面。
HAMR技術最大的特點是在硬碟內部整合雷射發射元件
以近場光的方式來提供相應的細小的雷射光束照射到寫入點
從而對碟片微粒進行加熱的方式來輔助磁頭進行寫入。硬碟的介質被加熱後
其屬性就產生了變化,磁性微粒從而能夠按照一定的方向被磁化之後
資料位元就形成了二進位的表示。當此行微粒快速冷卻之後
這些已經可寫入磁片的資料會變得穩定,從而達到永久存儲資料的目的
Seagate公司認為推出16TB HAMR驅動器 每GB成本降至0.02美元以下
這一成本水準在市場上對比SSD將具備較大優勢。目前的SAS SSD產品每GB成本約為0.55美
元
而3D TLC(即三層單元)快閃記憶體的成本則在每GB 0.20到0.30美元之間。
