Here's how to use a solid-state drive system and some things to note: 1. Why the need for solid-state hard disk loading system Solid-State hard drive systems can lead to rapid computer performance, especially for day-to-day operations, because the system disk is responsible for the computer's main reading and writing operations. Traditional hard drive due to the internal transmission rate of the problem, read and write speed on average only in 100mb/s, and

Today, Hao haocodeCodeCode is very hard, just escape from the Ubuntu on the mechanical hard disk, return to the SSD win7 preparation for entertainment. Well, I decided to kill him. Why don't I hear a headset when I turn on Three Kingdoms? Unplug the disk and restart it after it is killed. Kill, okay. I am very upset when I come up. After the installation is complete, restart and clean the environment ~ Headphones are still blank. The driver can also

What about a solid state hard drive? The solid-state drive has been in use for a long time, especially when there is little storage capacity, which will occur more or less quickly. Behind this is the memory data write/Erase mode restrictions, as well as the hardware and firmware based on SSD layer, including Trim, garbage collection (garbage Collection) and other mechanisms of operational effectiveness. Therefore, discretion to implement secure erase

. currently, utmp generally has a utmpx file as a supplement to log records. don't forget to wipe this pp. :) Wtmp The wtmp file records user logon and exit events, which are similar to utmp. however, as the number of logins increases, it will become larger and larger. some system ftp access is also recorded in this file. it also records the normal system exit time. you can use the last and AC commands to access it. Syslog Messages By viewing/etc/sys

Ceph environment setup (2)1. There are three layout hosts: node1, node2, and node3. Each host has three osdks, as shown in figure. osd1, and 8 are SSD disks, 4 is the SATA disk. Each of the three hosts has a Monitor and an MDS. We use osd1, 3, and 4 to create a pool named ssd, in the form of three copies, osd0, and 2, 4 to build a Pool named sata, in the form of Erasure code, k = 2, m = 1, that is, use two

The benefits of solid-state drives: 　　Benefits 1. Solid State Drives Fastspeed is the biggest advantage of solid-state drives, especially the random read and write speed is hundreds of times times the average hard drive. 　　Benefits 2. Solid-state HDD power consumption is lowerthe maximum power consumption of a common hard disk is about 5-10w, while solid-state drives are usually less than 3W and more environmentally friendly. 　　Benefits 3. Solid State Drive Completely noiselessMany people wil

What are the optimization techniques for solid-state drives? Solid-State hard disk is called fixed disk, is a solid-state electronic memory chip array made of hard disk, its chip operating temperature range is very wide, business regulation products (0~70℃) of the product ( -40~85℃). Although the cost is high, but also is gradually popularized to the DIY market. The new generation of solid-state drives generally adopt SATA-2 interface, SATA-3 interface, mSATA interface and Cfast interface. Let

Symptoms and causes of SSD freezingI7 ● SSD choppy symptomsA friend who recently bought a new SSD may be troubled by a problem, that is, the system stops responding or gets stuck for no reason. The specific situation can be shown as follows according to the SSD master:1. Sandforce control: during normal computer operat

The CEpH experiment environment has been used within the company for a period of time. It is stable to use the Block devices provided by RBD to create virtual machines and allocate blocks to virtual machines. However, most of the current environment configurations are the default CEpH value, but the journal is separated and written to a separate partition. Later, we plan to use CEpH tier and SSD for some optimizations: 1. Write journal to a separate

As we all know, solid-state hard drive optimization (hereinafter referred to as SSD) can make the use of disk more efficient. Here we will teach you how to optimize your SSD in different ways. Data that may be stored during optimization is lost, so it is recommended that you back up the original data first. SSD optimization is a very targeted setup process, this

How do I differentiate the solid-state drives of the M.2 interface? M.2 is Intel led the development of a new generation of interface standards, with a smaller size, faster interface features, the current main specifications are the following, mainly the length is not the same. The image below is a two-m.2 SSD: The short one is the Shadow Armor War m.2 128GB Long is the Shadow Armor War m.2 256GB These two are m.2 interfac

applications of solid-state hard disk generally have different interfaces. Solid-state hard disk compared with traditional mechanical hard disk, interface specifications are more easily confused by the initial users, the following is described below: 　　Mainstream common--sata interface SATA interface is no longer a new technology, since 2001 SATA 1.0 to the current SATA2.0 and SATA3.0, has made SATA as the current solid-state hard disk main interface. In terms of current usage, SATA2.0 users

Can TRIM operations be performed in RAID? I wonder if you have considered the following question: can TRIM operations be supported in RAID? Imagine how to unmap the data block in the SSD by using the TRIM command after the RAID is created on the SSD and the application software (File System) runs directly on the RAID software? It seems that this is not a problem. In fact, it is a big problem for RAID. From

Intel has recently been exerting its power at the channel end, and the computer stores, 3C stores and the manufacturers of the manufacturers have been pushing the pole. However, in the face of "super extreme" this jerky vocabulary, a large number of users do not understand their meaning. Many consumers think "ultra-extreme" means super lightweight and super performance. There are many consumers do not understand the use of expensive SSD, there are a l
