SSD 比 HHD 快得多。然而,從容量的角度來看,舊式硬盤通常提供更多的存儲空間。正因為如此,許多個人和企業仍然依靠 HHD 來進行大型備份。今天,三星宣佈將會大批量生產具有巨大容量的固態硬盤(SSD),據了解,即將大量生產的“PM1643”提供了瘋狂的 30.72TB 存儲空間!這是通過使用 32 x 1TB NAND 閃存實現的。

“Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging and associated software. Included in these advancements is a highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD,” 三星電子表示。
該公司進一步表示,“除容量翻倍外,性能水平也有顯著提升,幾乎是三星上一代高容量 SAS SSD 的兩倍。基於 12Gb / s SAS 接口,新型 PM1643 驅動器具有隨機讀取和寫入速度分別高達 400,000 IOPS 和 50,000 IOPS,連續讀寫速度分別高達 2,100MB / s 和 1,700 MB / s,分別約為隨機讀取性能的四倍和連續讀取性能的三倍典型的 2.5 英寸 SATA SSD“。
