典型的read操作需要两步(以图一的三星硬件为例): 从介质中读取页面到 4KB 数据寄存器,需要25us。 通过数据总线将其移出,100us/page。 2.2 Erase 在写入闪存中的页面之前,该页所在的块要被erase。这将破坏块中原来的内容(通过将每一位设置为值 1); 因此,在执行擦除之前,必须确保块中任何有用数据已被复制到...
读取+写入快取( Read and Write cache)于NAS上的应用可分为两种形式。 第一种:是直接写入(Write-through)式SSD快取:数据数据会同时写入SSD快取及主要储存区HDD,SSD快取可以提供高速的数据传输跟数据检索,而主要储存区HDD可以保护数据数据不会因SSD的故障而产生损失,也因此直接写入式SSD快取也可以仅使用单颗SSD或...
