m.2 and SATA3 solid state hard Drive area Don't What do you mean, m.2? M.2 is a new solid-state hard disk interface, is an alternative msata new interface specification, which we used to refer to NGFF, English is all called: Next Generation Form Factor. M.2 Interface SSD The main advantage is that the volume is smaller than the traditional SATA3.0 and mSATA, and the reading speed is faster, which is better for some mobile device compati

For work requirements, read some flashcache content and record it as follows: Implementation Flashcache is a new open-source project developed by the Facebook Technical Team. It uses SSD hard disks to cache data to accelerate a MySQL kernel module. We can see that it was initially used for database acceleration, but it was also designed as a general cache module for any application built on Block devices. Working principle. Based on device Mapper,

Solid state storage not only changes the storage industry, but also affects the entire computer field. We have seen that flash memory has completely changed the consumer electronics field, replacing rotating disk drives in almost every category of consumer electronics.This enthusiasm is also extending to the data center. Database Administrators, System administrators, and application system owners have begun to realize the benefits of solid state storage. They see the advantages of solid state s

How to pick a solid state drive? Open a large electric dealer website SSD Solid State hard disk Display page, currently can see 40 different brands. This may confuse many people, how can there be so many brands? To know, the mechanical hard disk market after the brutal competition baptism, currently left several famous brands: Seagate, Western Data (west), Toshiba, Hitachi, which Hitachi has also been acquired by the West. Mechanical hard disk manufa

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

How to build an Android development environment on a single machine Old saying: to do good deeds, you must first sharpen your tools. To learn about Android development, I lost my blood and changed my computer. As the saying goes, it is a bit paranoid to sharpen the knife without mistake and make good use of the steel on the knife. In order to maximize the potential of the new book, I spent a long time doing configuration and optimization. However, the old saying goes completely correct from the

　　 disk features and application scenarios The disk is divided into local SSD disk and cloud disk, in which the cloud disk is divided into efficient cloud disk, SSD cloud disk and ordinary cloud disk. The following is an introduction to the characteristics and usage scenarios of these disks. High Efficiency cloud Disk SSD Cloud Disk Common Cloud Plate Local

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

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

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

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

With the innovation of storage technology, solid-state hard disk (SSD) plays an increasingly important role in enterprise application. The advantages of SSD performance are obvious compared with traditional hard disk, whether it is read-write or random access speed. But traditional hard drives are mature products that have existed for decades as mainstream storage media and have been supported by a series o

Practical recruit one: specific speed The biggest advantage of SSD is high speed reading and writing speed. Traditional hard drive lane speed in the reading and writing 70m/s, and professional enterprise-level SSD can reach read and write 120m/s above, random read and write speed, ioPS read is hard drive about 100 times times, write is about 10 times times. Solid-state hard disk speed is mainly to look at

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.

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
