As SSD benchmark:
After purchasing hard drives, SSDS, USB flash drives, storage cards, and other devices, we all want to fully understand their performance, especially the disk read/write speed. Or, after the device is installed, you also want to test whether the read/write speed of the hard disk meets the manufacturer's nominal value.

Let's look at the difference between SSD and traditional mechanical hard drives. The following figure can be seen, the traditional mechanical hard disk by the disc, magnetic head, rotating shaft, control motor and other parts, working disc rotation, magnetic head positioning in the disc at the designated location for reading and writing operations, in a sense and the structure of the old phonograph similar. The advantages of traditional hard disk are
SSDs are different from traditional disks in organizational form, with the concept of sector, cylinder, and disk. SSD Flash storage is completely different and SSDs are made up of Page,block,plane,die.The Linux kernel considers SSDs as a block device, and a block device like a disk model. The FTL inside the SSD hides the relationship of the SSD Page,block,plane,d
Failure phenomenon:
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 drives).

Simple Optimization of SSD hard drive on Ubuntu
1. Set the correct mounting option and enable TRIM.
After Linux is installed, this is very important.
To maintain long-term stability and speed, SSD needs to enable TRIM, which enables SSD to truly erase the materials marked on the chip during non-peak read/write times. This example is based on the ext4 system. For
Use the DD command in Linux to test the read/write speed of USB and SSD hard disks.Disk Drive Speed
The disk drive speed is measured by the amount of read/write data per unit of time. The DD command is a simple command line tool that can read and write any data block on the disk and measure the read/write speed.
In this article, we will use the DD command to test the reading and writing speed of USB and SSD
Key points for using SSD
SSD usage basically does not need to optimize, only the following several places need to note:
1, on the AMD series of Chip motherboards, Intel's SSD performance may be reduced, so you can choose the third party company's products.
2, the Win7 system will be shut off can save a large part of the hard disk space.
3, virtual memory, 4

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 MySQL build index on SSD and use in
I finally installed UbuntuKylin13.04 on the SSD. It was very difficult! It is recommended that you install it using USB live. The speed is very fast. The actual measurement is 128 gb ssd + 8 GB memory. The installation is completed in about 8 minutes during online download. Step 1: Disable the ext4 log function Note: The system mount can not disable the log function, so you need to use the installation of t

1. BackgroundWhen doing a vsan experiment, you need at least one SSD disk as the read/write cache. If there is no SSD disk, we need to mark the normal HDD disk as SSD. Parameters need to be modified.2. StepsThe first step: Find the ID of the disk that needs to be modified to SSD: Red is the ID of the disk as follows[Em
