Focus on SSDs has been around for some time, the previous few years SSD capacity is small, more importantly, its limited life and expensive prices so that SSD can only be used as a storage area of the accelerated media exist, if anyone who want to use SSD as a disk array, the system is a bit too crazy. As a result, in

Can ssd be used as a redo disk? 1. ssd has write wear and tear, and the ssd write performance is not very good. ssd is only very good for random reading, because it does not need to be searched. Ssd is easy to damage. 2. index tab

Do you want to partition your SSD? Some people say that SSD is best not to partition, will affect the use of performance and life, is this so? On the SSD is good or not partition good, is a more interesting question, which will involve a lot of SSD related knowledge, the following small series to detailed introduction.

The ThinkPad machine comes standard with a Sandisk solid state drive. An error is reported using the built-in detection software (Lenovo Diagnostic or LSC), as shown below:Smart Status: FailedIn some operating systems, the following error occurs:Note: the machine or hard disk has no problems during use.Impact scope:Model: ThinkPad T440, T450, T440s, T450s, X240, X250, L450, L550Affected operating systems: windows 7, windows 8, windows 8.1, and windows

Some time ago in developing a system that uses SSD for caching, a large amount of disk caching occurs when writing data at high speed. Too much disk caching is very dangerous if there is a problem with the machine if it is not written to disk in a timely manner, which can result in a lot of data loss, but if the data i

The use of SSD hard disk is becoming more and more common, its powerful performance can help the computer to improve the system and software running speed, so by many users, but a lot of computer novice for how to install SSD hard disk still have many questions, the following small series will explain the

Disk defragmentation is the Disk Cleanup optimization tool with Windows, when the computer does not install other optimization software, you can directly use Disk Cleanup to solve the miscellaneous files in the hard drive, to ensure the life of the hard disk, but also to improve the operating efficiency of the computer

How to choose mechanical hard disk and SSD The giants of the tide we all see in the eyes of pain in the heart, after all, they are accompanied us through a lot of years old brand. And for consumers, in the end should buy large-capacity mobile hard disk products good or fast technology strong (mobile) solid-state drives good? Why did the traditiona

files are in use. DiskSim is initially separated from a large, system-level simulator, so it can be easily transplanted to the entire system simulator (such as porting to SimOS ). What DiskSim Does Not Do?DiskSim only simulates and reports storage subsystem performance-related aspects. It does not simulate the behavior of other computer system components, or the interaction between components and the storage system. DiskSim simulates the performance of the hard

Accelerate MySQL index query using an SSD Hard Disk For more information, see: http://www.javaarch.net/jiagoushi/index.htm If the data volume is large and the SSD capacity is not large, you can save the index data to the SSD to store the table data on the old hard disk. S

Use an ssd hard disk to accelerate mysql index query. If the data volume is large but the ssd capacity is not large, you can consider storing the index data on the ssd, store the table data on the old hard disk. So how can mysql build index on

If you are using or preparing to buy SSD, you will certainly have some understanding of it. Now because the structure of solid-state hard disk and mechanical hard drive are fundamentally different, solid-state drives to achieve real performance needs of the trim instructions and other special means. But most people do not know, or are not aware of, in addition to some newer solid-state hard drives, partiti

Solid-State hard disk storage medium is divided into two types, one is the use of flash memory (Flash chip) as a storage medium, the other is the use of DRAM as a storage medium. 　　Solid-state hard disk based on flash memory Flash-based solid-state drives (IDE flash disk, serial ATA flash disk): Flash chips are used

perhaps SSD (solid state Drive) compared to the mechanical hard drive, the speed rise is really fierce, the computer boot to enter the system from the minute to the full turn into seconds reading time. In fact, the benefits of SSDs is not only in the speed of change, if only hundreds of yuan investment in exchange for these, it is too young! SSD structure is relatively simple, there is no rotating disc, ma

The Windows 8 Index is a low-level service in Windows that specializes in providing fast searching for files, documents, and e-mail. In addition to creating a set of indexed data on the hard disk for the first run, Indexing Service starts every time a file changes or a new file is added, which is why many friends are complaining that their computer often finds the main reason for the hard drive (and there are other other things that can drive the hard
