Samsung宣布推出新款PCIe 4.0 SSD PM1733和PM1735,面向OEM大客戶市場,算上所有容量(0.8TB~30.72TB)和板型(2.5寸U.2或擴展卡)的話款式多達19款。
除了得益於PCIe 4.0接口帶來了最高連續寫入3.8GB/s、連續讀取8GB/s、隨機讀取1450K IOPS、隨機寫入260K IOPS的傲人速度,Samsung對主控軟件算法的優化也達到新高度。
最值得一說的便是芯片故障防護技術(FIP),號稱可以讓SSD永遠不壞、不掉。Samsung稱,這是存儲行業60年來新的里程碑,即便SSD出現芯片級故障,無需像傳統方案那樣更換整塊SSD,取而代之的激活糾錯算法,把受損數據重定向正常工作區中。
Samsung舉例,30.72TB的PM1733中512顆NAND芯片中任何一顆出現故障,都不會造成數據損失或者掉盤。
此外,Samsung還介紹了SSD虛擬化和V-NAND機器學習技術,前者可以把一塊SSD最多劃分成64個小盤,後者則是為提高可靠性。
