BACKGROUND OF THE INVENTION Solid-state memory devices encompass rewritable non-volatile memory devices which may use electronic circuitry for storing data. Currently, solid-state memory devices start replacing conventional storage devices such as ha…

这周我看了<Inside Solid State Device>一书,了解了解SSD作为软件的补充. 固态硬盘区别于将数据以磁形式存储的机械硬盘,使用了一种名为NAND的闪存颗粒,以电信号的形式存储数据.存储介质利用半导体的特性,以高低电平来标记数据的类型.NAND颗粒又以最小存储单元的堆叠形式不同而分为SLC(single-level cell)颗粒.MLC (multi-level cell)颗粒和TLC(triple-level cell)颗粒.单个slc存储单元有0和1两种充电值,(高…

A mechanism is provided in a data processing system for reliable asynchronous solid-state device based de-duplication. Responsive to receiving a write request to write data to the file system, the mechanism sends the write request to the file system,…

固态硬盘(Solid State Drives) 学习了:https://baike.baidu.com/item/%E5%9B%BA%E6%80%81%E7%A1%AC%E7%9B%98/453510?fr=aladdin 一般它擦写次数普遍为3000次左右,以常用的64G为例,在SSD的平衡写入机理下,可擦写的总数据量为64G X 3000 = 192000G,假如你是个变态视频王每天喜欢下载视频看完就删每天下载100G的话,可用天数为192000 / 100 = 1920,也就是 1920…

A method for garbage collection in a solid state drive (SSD) includes determining whether the SSD is idle by a garbage collection module of the SSD; based on determining that the SSD is idle, determining a victim block from a plurality of memory bloc…

BACKGROUND OF THE INVENTION A SSD apparatus is a large-capacity data storage device using a nonvolatile semiconductor memory such as a NAND flash memory. The SSDapparatus has an interface which is the same as a magnetic recording hard disk drive (HDD…

刚开始接触NVMe,对此理解不深,如有错误敬请指出 1.1概述 NVM ExpressTM(NVMeTM)接口允许主机软件与非易失性存储器子系统通信. 此接口针对企业和客户端固态驱动器进行了优化,通常作为寄存器级接口连接到PCI Express接口. 注意:在开发期间,此规范称为Enterprise NVMHCI. 但是,在完成之前,该名称已修改为NVM Express基本规范. 此接口适用于客户端和企业系统. 有关从修订版1.2.1到修订版1.3的更改的概述,请参阅http://nvmexpr…
