An SSD is the best upgrade for any computer due to its fast access times. But that also means the applications stored on a slower HDD will open slowly as
Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice...
What I would like to do is: split the SSD into a 100GB partition for the OS and a 28GB partition that would be used as cache for the slow HDD. Is it possible? BTW Intel RST is not on the latest version (apparently it hasn't been certified by Dell yet),...
This device has a 32 GB SSD drive which can act as a SSD cache drive for the 2 TB HDD (which is my desired configuration). Windows Device Manager (and Disk Management) doesn't show the SSD HD, probably due to Raid 0 configuration. I have...
SSD盘作为cache来增加读写速度，要使用dm-cache，将SSD用作HDD盘的Cache，也可以理解为内存。本文使用256KB（262144B）作为cache block的大小 首先查看可用于cache的实际大小： 1.metadata的大小为 4MB+(16B * nr_blocks) 计算方法 nr_blocks是cache设备的block的数量。2.计算metadata占...
家用SSD做读cache没有任何意义,因为基本上没有热数据。写cache的话,真不如直接拿一块ssd做下载盘了。不过我问过qnap的人,他们的意思是家用SSD就没意义,因为最大千兆网,HDD足够了。 5楼2021-04-22 11:10 收起回复 Nebula28 托儿所 1 但是PT下载是非常碎片的存储,如果一个种子同时从100多个peers下载文件,固...
文章从硬盘驱动器(HDD)扇区大小的历史演变出发,逐步引入SSD中IU的设计理念及其背后的考量。通过对比分析不同IU大小、L2P表结构以及预留空间(OP)等关键参数,阐述了它们对SSD容量、性能和耐久性的深远影响。 此外,文章还前瞻性地探讨了多种优化IU容量的创新方案,如增加L2P表位数、子驱动器磨损均衡技术以及增大IU页...
群晖DSM系统在“PLUS”以上级别的NAS设备上支持SSD Cache技术,Synology 的SSD Cache技术白皮书(英文版)描述了它是如
上图可以看到,由于256GB和512GB固态硬盘拥有大小不一的SLC Cache,CrystalDiskMark不同容量的测试中其衰减程度是不一致的。常见的TLC硬盘如果顺序写入速度500MB/s的话,SLC缓外顺序写入速度基本快要腰斩;而目前最新的产品QLC固态,基本缓外顺序写入速度就是100MB/s以下了。100MB/s以下是什么概念,还不如HDD机械硬盘的...
root@xxxx:~$ mount /dev/mapper/hdd-origin /mnt/cache 9.配置开机自动加载并挂载,需要手动配置两个文件放到/etc/init下: root@xxxx:~$ sudo vim /etc/init/ssd-cache-wait.conf # Start monitoring with inotifywait (will block) after the filesystemis# mounted, when the filesystemisunmounted, tear...
