how to reformat ssd

SSD provides incredible performance for the storage system, which is 10 times higher than the fastest mechanical hard disk. However, because SSD write performance is affected by block erasure latency, SSD is usually used as a read device. However, this does not mean that SSD does not improve the write performance. In f

Can traditional RAID be built on SSD? When asked whether traditional RAID can be built on SSD, the first response should be "yes, but Trim command support is required ". On the Internet, we can also see that many people use SSD to create RAID, but basically it is configured as RAID 0 or RAID 1. Few people will build RAID5. Why? The answer is very simple. If you c

Years later, the use of their spare time and intermittent will caffe SSD source read, although the middle due to work for a period of time, but finally completed successfully, SSD source reading is also this year's annual plan of the more important one of the content, completed or very fulfilling. after reading the code, one of the biggest experience is that before the paper a lot of confused my details now

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 previous years, both academia and industry ha

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.

So far, I have been running the master Informix development database server on SSD for more than a year. My development server is equipped with 12 CPU cores, 24 gb ram, 5 TB disk space, and a 5 gb ssd. I used this server to develop the Informix Data Warehouse project and run So far, I have been running the master Informix development database server on SSD for mo

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 tablespace and temporary tablespace are good cho

SSD solid-state hard drive How to optimize the use of solid-state hard drives more slowly how to do? Today, this article mainly with the introduction of SSD solid State hard drive optimization of some knowledge, mainly for some netizens often said they buy the solid-state hard disk speed is not fast, or feel that the SSD and traditional HDD hard drive gap betwe

of the computer. So we say, now the bottleneck of computer hardware is the traditional mechanical hard disk. That being the case, we can see that improving the performance of the hard drive can improve our experience of using the computer, so SSD turned out. SSD because of its storage medium and principle and traditional mechanical hard disk is completely different, so greatly improve the read and write s

For more information about how to use an ssd hard drive to accelerate mysqlindex, see www.javaarch.netjiago ushiindex.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 .? So how can we make mysql build index on ssd and

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are o

After replacing the SSD under Mac Pro, it is cumbersome to change the SSD to AHCI mode if Win7 is installed. This article describes how to change the SSD in Mac Win7 to AHCI mode driver and the processing of several common problems.How to change the SSD drive mode of Win7 to AHCI when Lion and Win7 dual system coexist1

4K corresponds to 4096HDD Mode:First, let the SSD run in AHCI mode:AHCI, the full name Advanced host controller Interface, which is the high-level hosting controllers interface, is more suitable for SSD SATA storage device communication protocols than the older "IDE" virtual mode. In AHCI and IDE mode, the SSD's performance gap percentage is around 65%. Therefore, it is recommended that

I. first, review the read and write features of SSD (1) Limited write times; (2) best random read performance; (3) Good sequential read performance; (4) Poor sequential write performance; (5) the random write performance is the worst. In terms of storage, different content of SQLServer has its own unique personality. The following lists TempDB, Data, indexes, and transaction logs respectively. I. first, review the read and write features of

Compared with the faster rcnn, the speed of the target detection has b

analyzed. Locate the possible cause of the problem and try to make the following adjustments on the 24 master database: After the above adjustments, I/O became stable and there was no larger fluctuation. For the sake of insurance, project A decided to use an SSD-equipped model to migrate the master database, and migrate the 24 slave database 27. After the migration is completed, the SSD and MySQL InnoDB pa

When asked whether traditional raid can be built on SSD, the first response should be "yes, but trim command support is required ". On the Internet, we can also see that many people use SSD to create raid, but basically it is configured as RAID 0 or raid 1. Few people will build RAID5. Why? The answer is very simple. If you configure parity-raid like RAID 5 on the basis of

This article is for reading book next Generation Databases:nosql, Newsql, and Big Data Chapter 7th: The End of Disk? SSD and In-memory databases notes.The disk is dead?Bill Gates said in 1981: 640K of memory should is enough for anybody. In 2001, he realized that the previous statement was wrong: I ' ve said some stupid things and some wrong things, but not that. Since the birth of the first database, database experts have

I haven't updated my blog for a long time. A while ago, I experienced my first job hopping, which is much harder than I thought. After all, it was the first job and it was quite sad to leave. The new job has just begun, and we hope everything will go well. This blog was written during May 1, and is officially posted today. It is a good habit to write a technical blog. I want to keep it! When I was in the previous job, I always wanted to try Flash/SSD

1. The master chip is the core of SSD and determines the performance and stability. Mainly include Intel, JMF, Samsung, Indilloud, among which intel and Samsung are the leader, indilloud is the new expensive, and JMF is mainly oriented to low-end markets. 2. the cache chip assists the master chip in data processing to improve and stabilize performance. Some low-end products will save the cache dram chip for cost reasons. 3. NAND Flash chips mainly inc
