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
With the price of SSD solid-state hard drives down, later assembled computers to use SSD solid-state hard drive will become mainstream, at present, SSD solid-state hard disk capacity is small, and the price than mechanical hard drive to have no advantage, compared to ordinary mechanical hard drive, the gap between the big price. Believe that the
SSD solid-state drives know that if the SSD partitions do not have 4K alignment, the performance will be a discount. But maybe someone with the same encounter this situation, clearly zoning when the choice of 4K alignment, but after the system with as SSD benchmark this tool after detection is extremely depressed, why C disk will show not 4K alignment?

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.
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
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 ssd and use index data on ssd?
SSD interface is diverse, the mainstream SATA3.0 interface most common, the recent very hot M.2/PCI-E interface, once extremely the SSD most loves to use the mSATA interface, now has appeared a u.2 interface, must pedal m.2, replaces Sata, becomes the future SSD mainstream choice? What exactly is the U.2 interface? Today's SS

compared with the desktop, we have a relatively low demand for notebook performance, so in the process of upgrading the notebook hard drive is the pursuit of performance or large capacity, or both? Small series will come up with three solutions to discuss with you.
For the different needs of the user groups, we will be the notebook upgrade program roughly summed up in the following three kinds:

When SSD is optimized,/var/log is placed in the ramdisk of tmpfs. restart causes the apache2 and nginx directories in/var/log to be lost, and apache2/nginx cannot be started.

The biggest difference between SSD and HDD is that it does not have the necessary mechanical parts of the HDD, the disc, the head rocker arm, which is determined by the different working principle of two kinds of hard drives. SSDs save time in mechanical parts movement compared to HDDs, and the primary storage element NAND flash used by SSDs is an electronic component, so its data travels much faster than HDD.In addition, according to the test, the HD
