ssd raid5

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 th

SSD win7 Optimization guide: nine Win7 SSD optimization methods with the price of solid-state drives falling, solid-state drives are now widely used, and some new notebooks and assembly computers are also beginning to adopt solid-state drive platforms, not to mention that the use of solid-state drives has become standard, Although the SSD is fast, but does not un

single disk. 100% data redundancy means that there is no need to rebuild data in the event of a disk failure. It is important to note the inefficient use of disk capacity-the highest cost for all RAID types (100%).3,RAID10 Features: RAID-10 is a combination of RAID-1 and RAID-0. This configuration requires at least 4 hard drives, with the best performance, protection, and capacity in all RAID levels. The RAID-10 contains paired mirrored disks whose data is stripped across the array. In most cas

　　SSD Solid State hard disk installation steps 1, first SSD with 2.5 inch to 3.5-inch hard disk rack installed to the hard disk bit. 2, the boot into the BIOS, the disk mode is set to AHCI mode (basically all motherboard's default disk mode is IDE mode, this is to the mechanical hard drive to provide compatibility, but not at all suitable for SSD). Meanwhile, t

SSDs are structured and run differently from traditional hard drives, and are strongly recommended after purchase to achieve optimal operational performance and extend the life of the SSD. The first part of the following is some of the things you can find on the internet about SSD drives, which have been introduced a lot, We will not go into the details here. For more information, please find the relevant c

recently re-spread on the database, the company's core database every day IO full, in the study with SAS 16*RAID10, or RAID10 ssd*6, or FIO;the principle, no raid-5 for database; eh; the root of all evil ;No.2 principle, most of the time, the database does not need too high CPU, now 2 sockets are basically enough, more MySQL is not used;No.3 principle, large memory, high IO, is the necessary condition of modern web-based database;now the big companies

SSD potential release is the potential performance of a single-button, fully-automated, solid-state drive. Significantly enhance SSD efficiency, reduce hard disk drive read and write times, effectively increase the life of solid-state drives.SSD Potential release Features:1, only need to carry out a comprehensive physical examination of the SSD, after any file po

solid-state drives, choose SLC, MLC, TLC where to go? Because the MLC structure of the flash chip price is relatively moderate, the service life and the rate is quite good, on the current market structure, most SSDs are using the MLC Flash chip architecture.Although the SLC, MLC, TLC chip architecture rate is very different, but relative to the traditional mechanical hard disk, are the quality of the soaring, so I recommend different people to use different flash chip architecture of solid-stat

1, the replacement of solid state hard drive (SSD) First turn off the computer, then remove the mobile battery (note: There are two batteries, the inside and together), unscrew the screws, open the back cover can be opened after the image: Only need to take away the hard drive, remove the need to unscrew a screw, and then replace the solid State Drive (SSD) can be. 2, change the memory strip Because

The following switch from Baidu:Recently in preparation for testing, you need to see which machines are mounted SSD hard drives, Google has seen a lot of methods, but all foggy, do not know how to determine. SSD hard disk seems to use the SCSI interface, so according to the name of the drive letter is not to be judged. The last group of Eric God told LSSCSI Tools, try it, very simple, the display is also ve

Many people have encountered the server RAID5 hanging off, often lost a disk, the second disk immediately hung off.We all know that RAID5 once allowed a disk to be missing, RAID 5 is also a data check bit to ensure the security of data, but it is not a separate hard disk to hold the data check bit, but the data segment of the check bit interaction on each hard disk. This way, any one of the hard dr

4K Alignment is a very important operation when the SSD is partitioned, if there is no 4K alignment, it will result in the cross region reading and writing, not only affect the speed of solid-state drive, but also affect the SSD life. So, how do solid-state drives look like 4k aligned? Method One: Do not use any tool to view the method 1, first use "win + r" combination shortcut key to open th
