disagreement, and miniaturization in the notebook can be said to be imminent, because the notebook is not so large space to accept SATA large-capacity solid state, now the SATA solid-state is basically the removal of the CD-ROM and pallets added to"MSATA"is not very much like the new interface m.2 AH now. Indeed, M.2 's original intention was to replace mSATA. Increase speed with direct CPU consumption of two channels (lane)"SATA Express"Since we want to increase the bandwidth, but also to cons

Several methods of disk operation are available in Edkii, including synchronous/asynchronous, block operations/arbitrary operations.

maximum is 400mb/s. Currently UFS only Samsung can be put into production, used in its own Samsung S7 flagship machine. The newly released Xiaomi 5 also uses Samsung UFS, which is blown to "black technology". In addition, the good thing Apple certainly can not pull down, iphone6s uses the Apple self-developed NVME storage chip, its content is not open to the outside, but based on speculation is similar to UFS, its interface is based on the serial PCI

the ready-made Linux open source code on the market. The PMC data center I/O controller integrates with PMC's SAS extender, adaptec by PMC raid array card, memory card, and flashtec nvme solutions to provide a complete set of end-to-end solutions, it solves various storage requirements of data centers, including: high-density SAS and SATA server storage required for big data, hadoop, and computing nodes, large-scale disk connections in warm storage a

and reliability at a high price. However, not all SSDs are applicable. For database servers, you should use an SSD designed for server workloads, which protects data (for example, during power outages ). Avoid using commercial SSDS designed for desktop computers and laptops. SSD connected through NVMe or Intel OpTan technology provides optimal performance. Even if you remotely connect to a SAN, NAS, or cloud block device, SSD delivers superior perfor

How is the Android storage system optimized?The answer is I don't know ...Then why do you think you should write this article? I wanted to write down what I knew, mainly because one evening and a colleague discussed the optimization of the Android phone storage system. People who have used an Android phone may have this feeling that the system will become slower after the phone has been used for a long time. Slow, and one of the most important things about Android is the storage system. We now h

New magazine Firelord series overall upgrade. We can see that its design has changed a lot on the basis of the previous generation of Pandora. The outer side of the notebook folding is equipped with a magnesium-aluminum alloy frame, which makes the fuselage more stable and firm. Fuselage before and after up to 300 air inlet holes, the internal configuration of the double 90 mm fan, two 8 mm copper tube, from the inside out to increase the heat dissipation, in the game to open the full effect of

Introduction Earlier article said, when encountering the high concurrency data storage layer, will first think of read-write separation, while high concurrency may mean that the data volume, a large number of query or update operations concentrated in a large table, the frequent use of locks, will lead to the decline in access speed, and the amount of data may exceed the capacity of a single machine, So we thought of the sub-database. But before the sub-table, I would like to say a few more wo

shown below: Vm.swappiness=0 kernel.shmmax=21474836480 net.core.rmem_max=4194304 net.core.wmem_max=4194304 kernel.sem=50100 64128000 50100 1280 vm.dirty_background_bytes=33554432 4. When using XFS, the default block size for PostgreSQL is 8KiB, but in the current Linux environment, running "Mount XFS" will eject the "feature not implemented" error, so the block size should be adjusted to 4KiB. An increase in the number of allocation groups means that more paral

Hard drives are an indispensable storage device in today's it world, requiring hard drives, whether it's a home PC, workstation or server. With the development of technology, hard disk technology is also increasing, interface diversification (SATA,SAS,SCSI,FC,NVME), storage media Diversification (HDD,SSD), hard disk in IOPS,BW and capacity has been greatly improved.Hard disk before use are required to partition, a hard drive from the factory to the ac

performance will also be reduced, not one upgrade in place, may need to upgrade again in the future. But this kind of collocation for young users, especially for the game, large-capacity program hosting needs of large users, if your budget is not sufficient, but also willing to try to do the operation, in the original volume of the capacity of this disk at the same time with SSDs to improve the performance of the platform, but also suitable.

" still advocate the use of rotating disks (mechanical disks). Frankly speaking, when it comes to manipulating databases, these arguments are often outdated or completely wrong. Today, SSDs offer considerable performance and reliability at a high price. 　　 However, not all SSDs are applicable.
